DevExpress控件学习总结
1、Navigation & Layout
1.1 Bar Manager
如果想在窗体或用户控件(user control)上添加工具条(bars)或弹出菜单(popup menus),我们需要把一个不可见的控件(component)BarManager(Navigation&Layout)拖放到这个窗体或用户控件上。这个控件维护工具条在窗体上的布局,处理用户的行为(processes an end-user's actions),提供一些定制功能等等。这个控件维护工具条、工具条项、工具条项目录这三者的集合(It maintains the collections of bars,bar items and bar item categories.)。所以我们可以使用bar manager的一些方法去添加、删除、访问这些工具条元素。
注意:1)一个窗体上只能放置一个bar manager控件。
2)由于BarManager控件与RibbonControl控件可能会彼此冲突,所以不推荐在同一个窗体或用户控件上同时使用工具条和Ribbon控件。
当把BarManager添加到一个窗体或用户控件上后,我们就可以使用上下文菜单(context menus)、bar manager的定制窗口或它的设计器来创建工具条和工具条命令(bar commands)了。
相关控件属性
1.1.2、Toolbars
工具条是一个可视的控件,它用来显示各个项目链接。我们可以在工具条内显示由XtraBars库提供的任意项目链接,比如:按钮(buttons),静态文本(static text),子菜单(submenu)、编辑器(editors)等等。
1.1.3、 Bar Items
为了把多种元素(比如按钮,子菜单,标签,编辑器等)添加到工具条和菜单,我们需要创建合适的bar items。一个bar item是一个实现了特定功能的非可见对象。它定义了一个相应的元素如何显示在屏幕上,并决定了对鼠标单击事件的相应。
我们可以使用bar manager的Customize窗体上的Commands页来创建bar items。为了在逻辑上组织这些item,我们经常将它们分类。该窗体的左侧面板里显示了有效的目录,右侧面板显示了属于当前选中目录的各个bar item。选中一个bar item可以在属性窗口看到其属性。
1.1.4、Popup Menus
使用弹出菜单(popup menus),我们可以在控件上显示上下文选项或命令。弹出菜单是一个显示了特定项的窗体,用户可以选择这些项以执行相应的操作。使用PopupMenu控件就可以在我们的应用程序中使用弹出菜单。
通过BarManager的“名称”+“上的PopupContenxtMenu”属性绑定PopuMenus控件
注意:
在定制和使用popup menu之前,向窗体上添加一个bar manager并确保这个popup menu绑定了这个bar manager。默认情况下,在设计时(at design time)添加到窗体的弹出菜单会自动地寻找窗体内的bar manager,
如果找到的话,会通过PopupMenu.Manager属性将其绑定到bar manager。如果没有自动绑定到bar manager,那就通过PopupMenu.Manager属性手动绑定。
1.1.5、Categories
XtraBars允许我们将bar items在逻辑上划分为不同的类别(categories)。每个类别都是一组item,并且每个item都只属于一个类别(category)。类别不会对该类的item附加任何约束,分类只是为了对item进行有组织的访问。
用BarManagerCategory类表示一个类别。我们通过BarManager.Categories集合来添加、移除、存取类别。使用BarItem.Category属性,我们可以为每个item分配一个类别。
1.1.6、Bar Dock Controls
工具条停放控件(bar dock controls)是工具条(toolbar)的容器,它们位于窗体或用户控件内用以容纳工具条对象。有regular和standalone两种工具条停放控件。
regular bar dock controls是由BarManager自动维护的,我们不用手动去创建它们。它们停靠在容器(比如窗体)的任意一边,以显示工具条。
BarManager中的StandaloneBarDockControl属性用来在窗体内的任何位置显示工具条。我们需要手动绑定StandaloneBarDockControl控件
1.1.6.1 Regular Bar Dock Controls
当工具条停靠于容器(比如form)的任意一边时,regular bar dock controls将工具条的停靠位置显示出来。当创建 Bar Manager时,它会自动创建4个regular dock controls,并将它们停靠在窗体的相应边缘。
只有当一个工具条停放在一个dock control上时,这个dock control才是可见的。其他情况下,dock control的宽度都是0。当将工具条拖动到窗体的任意一边时,相应的dock controls会容纳并显示这个工具条。Bar.CanDockStyle属性可以指定工具条的可能停放位置。
一般情况下,在应用程序中是没有必要去改变regular dock controls的属性的。除非我们想要为停靠的工具条提供背景设置。Bar Manager会自动创建名为barDockControl1...barDockControl4的4个dock controls。每个dock control都是一个BarDockControl类。在设计时,我们通过在属性窗口选择相应的对象来访问dock control。此外,如果dock control是可见的,并且没有完全被工具条覆盖,我们可以单击选中它,以在属性窗口中显示它。
1.1.6.2 Standalone Bar Dock Controls
Standalone bar dock controls允许工具条停靠在窗体或用户控件上的任意位置,而不仅仅是窗体的边缘。创建一个StandaloneBarDockControl对象并且将工具条添加到其上就能做到这种效果。
像regular control一样,standalone bar dock controls可以在窗体或用户控件中随意放置。它们的Dock、Location和Size属性用来指定布局设置。StandaloneBarDockControl.AutoSize属性用来启用自动调整大小模式。在这种模式下,当向该控件添加或删除工具条时,该控件的大小是自动变化的。
使用Standalone bar dock controls的前提是该窗体或用户控件上已添加了BarManager控件。如果我们以编码的方式创建了StandaloneBarDockControl对象,那么我们就需要手动将其添加到BarManager的BarManager.DockControls集合中。
1.2 Bar Manager 的使用
1.2.1 Toolbars Customization
为了在窗体上创建bar和bar items,我们需要往窗体上添加一个BarManager控件。
1.2.1.1 creating bars and bar items on the form at design time
在设计时(at design time),当把BarManager添加到窗体上后,会自动创建三个空工具条,分别是:窗体顶部的主菜单栏、工具栏和窗体底部的状态栏。
主菜单栏通常是一个位于窗体顶部的工具条,其他的工具条不能和主菜单栏位于同一行。终端用户也不能关闭主菜单栏。默认情况下,用户可以拖拽主菜单栏,将其停靠至窗体的任意边缘。主菜单栏被赋予至BarManager.MainMenu属性。状态栏通常是一个位于窗体底部的工具条。用户不能拖动该工具条。BarManager.StatusBar属性赋值为该状态栏。在一个窗体上只有一个主菜单和一个状态栏。
默认情况下,工具条上有[Add]上下文链接(context links)。通过该链接,我们可以将bar items添加到工具条上。我们可以单击[Add]链接来激活bar item列表,然后从中选择需要的bar item。
选择一个item后,它即被添加到工具条上,同时文本编辑器也被激活。在此文本编辑器里我们可以编辑新添加项的名字。
按Enter键来结束编辑和该项的添加。
如果我们要添加一个子菜单(submenu),那么先选择sub-menu以添加菜单项,然后再次单击它,并通过[Add]添加新的bar item。
若想在设计时隐藏[Add]上下文链接,右击BarManager控件,然后勾去“show design time enhancements"选项即可。勾选这个选项,[Add]链接又会出现。
1.2.1.2 creating bars and bar items using the customization window
右击鼠标,使用BarManager的Customization窗口是向窗体添加工具条和bar items的另一种方式。
1)Manipulate Bars
切换到Customization窗口的Toolbars页,单击new,即可添加工具条。选择工具条列表中的一个,点击delete,即可删除该工具条。只有在运行时,Rename和Reset按钮才处于激活状态。
2)Adding Bar Items
切换到Commands页,点击modify按钮,然后选择Add菜单项,Add New BarItem对话框就会出现。在该对话框里,我们可以指定该项的分类、名字、标题(caption)等。当新的item创建后,我们就可以把它拖放到工具条上。
1.2.1.3 creating bars using the barmanager's designer
BarManager的设计器也是用来添加、删除、自定义设置工具条的一种方式。切换到Toolbars页,单击Add New Toolbar和Delete Toolbar按钮即可创建或删除工具条。
1.2.1.4 customizing items and links at design time
在设计时,当你选择一个链接(link),它就会在属性窗口中显示相应item的设置;
如果改变这个item的外观设置(appearance setting)就会影响到该item的所有属性没有显性设置的链接。为了避免对这些链接造成影响,我们可以这样做:
在设计时,右击这个链接,通过弹出的菜单来改变设置。
选项 描述
Reset 重置该链接的所有自定义设置。选中该选项后,这个链接的外观就会由相应item的外观设置控制。也可在代码中,调用BarItemLink.Reset方法以
将其恢复到默认值。
Delete 删除该链接。调用BarItemLink.Dispose方法也可达到该目的。
Change Caption 改变item 的标题。该值会应用于所有User caption没有设置的link。这个选项对应于BarItemLink.Caption属性。
change user 为某一link赋自定义标题,这样就覆盖了默认的item的标题。User caption只赋值于当前的link。该选项对应于BarItemLink.UserCaption。
caption
Default style 为某link设置默认的样式。每个link的的默认样式都可以是不同的。使用BarItemLink.PaintStyle属性来在代码里设置paint style.
Text only 项目链接(item link)被绘制为文本。
(always)
Text only item link 在菜单里被绘制为文本,在工具条里被绘制为图片。
(in menus)
Image and Text item link被绘制为图片和文本。
Begin a Group 在选中的link钱插入一分隔符,以将item links逻辑分组。该选项对应于BarItemLink.BeginGroup属性。
Visible 决定一个item link是否可见。该选项对应于BarItemLink.Visible属性。
Most recently 决定一个item是否指向最经常使用的link。勾选掉这个选项后,就会使该link位于最近使用项列表的底部。该选项对应用
used BarItemLink.MostRecentlyUsed属性。
1.2.1.5 How to obtain a value of the BarEditItem during editing
Object value=(barManager1.ActiveEditor as DevExpress.XtraEditors.ButtonEdit).EditValue;
1.3RibbonControl
1.3.1How to: Create a RibbonControl in Code
例1、
using DevExpress.XtraBars.Ribbon;
using DevExpress.XtraBars;
// Create a RibbonControl
RibbonControl RibbonControl = new RibbonControl();
this.Controls.Add(RibbonControl);
// Assign the image collection that will provide images for bar items.
RibbonControl.Images = imageCollection1;
// Create a Ribbon page.
RibbonPage page1 = new RibbonPage("Home");
// Create a Ribbon page group.
RibbonPageGroup group1 = new RibbonPageGroup("File");
// Create another Ribbon page group.
RibbonPageGroup group2 = new RibbonPageGroup("File 2");
// Create a button item using the CreateButton method.
// The created item is automatically added to the item collection of the RibbonControl.
BarButtonItem itemOpen = RibbonControl.Items.CreateButton("Open...");
itemOpen.ImageIndex = 7;
itemOpen.ItemClick += new ItemClickEventHandler(itemOpen_ItemClick);
// Create a button item using its constructor.
// The constructor automatically adds the created item to the RibbonControl's item collection.
BarButtonItem itemClose = new BarButtonItem(RibbonControl.Manager, "Close");
itemClose.ImageIndex = 12;
itemClose.ItemClick += new ItemClickEventHandler(itemClose_ItemClick);
// Create a button item using the default constructor.
BarButtonItem itemPrint = new BarButtonItem();
// Manually add the created item to the item collection of the RibbonControl.
RibbonControl.Items.Add(itemPrint);
itemPrint.Caption = "Print";
itemPrint.ImageIndex = 9;
itemPrint.ItemClick += new ItemClickEventHandler(itemPrint_ItemClick);
// Add the created items to the group using the AddRange method.
// This method will create bar item links for the items and then add the links to the group.
group1.ItemLinks.AddRange(new BarItem[] { itemOpen, itemClose, itemPrint});
// Add the Open bar item to the second group.
group2.ItemLinks.Add(itemOpen);
// Add the created groups to the page.
page1.Groups.Add(group1);
page1.Groups.Add(group2);
// Add the page to the RibbonControl.
RibbonControl.Pages.Add(page1); void itemPrint_ItemClick(object sender, ItemClickEventArgs e) {
//...
}
void itemClose_ItemClick(object sender, ItemClickEventArgs e) {
//...
}
void itemOpen_ItemClick(object sender, ItemClickEventArgs e) {
}

2.该控件通过TileGroup和TileItems添加Group和Item;
3、该控件通过TileControl.ItemClick事件执行选中的Item后执行的操作;
示例代码1:
using DevExpress.XtraEditors;
TileItem newTile = new TileItem();
tileControl1.Groups.Add(new TileGroup());
tileControl1.Groups[0].Items.Add(newTile);
示例代码2:
TileItem newTile = new TileItem();
//First Frame - Image only
TileItemFrame logoDXFrame = new TileItemFrame();
TileItemElement logoEl = new TileItemElement();
logoEl.Image = global::WindowsDev.Properties.Resources.additem_32x32; logoEl.ImageAlignment = TileItemContentAlignment.MiddleCenter;
logoDXFrame.Elements.Add(logoEl);
logoDXFrame.Elements[0].AnimateTransition= DevExpress.Utils.DefaultBoolean.True;
//Second Frame - Text only
TileItemFrame mottoDXFrame = new TileItemFrame();
TileItemElement mottoEl = new TileItemElement();
mottoEl.Text = "<Size=+2><Color=Sienna><b>Let's see what develops.</b></Color></Size>";
mottoEl.TextAlignment = TileItemContentAlignment.MiddleCenter;
mottoDXFrame.Elements.Add(mottoEl);
mottoDXFrame.Elements[0].AnimateTransition= DevExpress.Utils.DefaultBoolean.True;
//Global Tile Item Settings

1.9 RadialMenu控件
该控件是圆形菜单,可以以菜单的形式添加菜单项;
该控件的ShowPopup(Point point)方法用于显示圆形菜单;
2.0 PopupControlContainer控件
PopupControlContainer控件可以以面板的形式包含其他控件,可以DropDownButton控件的下拉框的格式出现,具体形式如图:
PopupControlContainer控件通过DropDownButton控件的DropDownControl属性进行绑定,在绑定后PopupControlContainer控件的AllowDrop属性要设成True;
2.1 HScrollBar控件和VScrollBar控件
许多控件需要滚动条,像ListBoxControl、CheckedListControl控件中已经集成啦滚动条,所以就不需要另加滚动条,但有些控件没有集成,像PictureEdit控件,当显示的图片过长时,不能在其已有的区域显示,就需要HScrollbar控件和VScrollBar控件;
示例代码:
using DevExpress.XtraEditors;
private void Form1_Load(object sender, System.EventArgs e) {
hScrollBar1.Width = pictureBox1.Width;
hScrollBar1.Left = pictureBox1.Left;
hScrollBar1.Top = pictureBox1.Bottom;
hScrollBar1.Maximum = pictureBox1.Image.Width - pictureBox1.Width;
vScrollBar1.Height = pictureBox1.Height;
vScrollBar1.Left = pictureBox1.Left + pictureBox1.Width;
vScrollBar1.Top = pictureBox1.Top;
vScrollBar1.Maximum = pictureBox1.Image.Height - pictureBox1.Height;
}
int x = 0;
private void hScrollBar1_Scroll(object sender, System.Windows.Forms.ScrollEventArgs e) {
x = hScrollBar1.Value;
pictureBox1.Refresh();
}
int y = 0;
private void vScrollBar1_Scroll(object sender, System.Windows.Forms.ScrollEventArgs e) {
y = vScrollBar1.Value;
pictureBox1.Refresh();
}
private void pictureBox1_Paint(object sender, System.Windows.Forms.PaintEventArgs e) {
e.Graphics.DrawImage(pictureBox1.Image, e.ClipRectangle, x, y, e.ClipRectangle.Width,
e.ClipRectangle.Height, GraphicsUnit.Pixel);
}
显示效果:
2.2、DocumenManger控件
MDI子窗体可以通过DocumentManger控件以nativemdiview对象或tabbedview对象的形式展现出来;
通过其ViewCollection属性添加View视图(子窗体),可以添加TabbedView、WindowsUIView、WidgetView、NativeMdiView四种视图;
通过Run Designer中Main下的Document给视图添加Document文档(显示的面板);
(NativeMdiView视图)通过代码实现如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using DevExpress.XtraBars.Docking2010;
using DevExpress.XtraBars.Docking2010.Views.NativeMdi;
using DevExpress.XtraEditors;
namespace DocumentManager_NativeMDI {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
int childCount = 0;
private void Form1_Load(object sender, EventArgs e) {
CreateDocumentManager();
for(int i = 0; i < 3; i++) {
AddChild();
}
}
void CreateDocumentManager() {
DocumentManager dm = new DocumentManager();
dm.MdiParent = this;
dm.View = new NativeMdiView();
}
void AddChild() {
Form childForm = null;
childForm = new Form();
childForm.Text = "Child Form " + (++childCount);
SimpleButton btn = new SimpleButton();
btn.Text = "Button " + childCount;
btn.Parent = childForm;
childForm.MdiParent = this;
childForm.Show();
}
}
}
实现效果如图:
(TabbedView视图)通过代码实现如下:
using System;
using System.Windows.Forms;
using DevExpress.XtraBars.Docking2010;
using DevExpress.XtraBars.Docking2010.Views.Tabbed;
using DevExpress.XtraEditors;
namespace DocumentManager_TabbedUI {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
void Form1_Load(object sender, EventArgs e) {
AddDocumentManager();
for(int i = 0; i < 3; i++) {
AddChildForm();
}
}
void AddDocumentManager() {
DocumentManager manager = new DocumentManager();
manager.MdiParent = this;
manager.View = new TabbedView();
}
int count;
void AddChildForm() {
Form childForm = new Form();
childForm.Text = "Child Form " + (++count).ToString();
SimpleButton btn = new SimpleButton();
btn.Text = "Button " + count.ToString();
btn.Parent = childForm;
childForm.MdiParent = this;
childForm.Show();
}
}
}
实现效果如图:
2.Data & Analytics
2.1DataNavigator
2.1.1绑定数据源:
例:List<int> datasource = new List<int>();
datasource.AddRange(new int[] { 0, 1, 2, 3, 4 });
myDataNavigator1.DataSource = datasource;
2.2GridLookUpEdit
2.1.2示例代码:
using DevExpress.XtraEditors;
using DevExpress.XtraGrid.Columns;
using System.Data.OleDb;
// A lookup editor created at runtime.
GridLookUpEdit gridLookup;
// A navigator control to navigate the "Order Details" table.
DataNavigator dataNav;
// DataView for the "Order Details" table.
DataView dvMain;
// DataView for the "Products" table.
DataView dvDropDown;
//...
private void Form1_Load(object sender, System.EventArgs e) {
gridLookup = new GridLookUpEdit();
gridLookup.Bounds = new Rectangle(10, 40, 200, 20);
this.Controls.Add(gridLookup);
dataNav = new DataNavigator();
dataNav.Bounds = new Rectangle(10, 10, 250, 20);
this.Controls.Add(dataNav);
InitData();
InitLookUp();
dataNav.DataSource = dvMain;
}
private void InitData() {
// Dataset to provide data from the database
DataSet ds = new DataSet();
string connestionString =
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\DB\\nwind.mdb";
// Connect to the "Order Details" table
System.Data.OleDb.OleDbDataAdapter dbAdapter =
new OleDbDataAdapter("SELECT * FROM [Order Details]", connestionString);
// Load data from the "Order Details" table to the dataset
dbAdapter.Fill(ds, "Order Details");
// Connect to the "Products" table
dbAdapter = new OleDbDataAdapter("SELECT * FROM Products", connestionString);
// Load data from the "Products" table into the dataset
dbAdapter.Fill(ds, "Products");
DataViewManager dvm = new DataViewManager(ds);
dvMain = dvm.CreateDataView(ds.Tables["Order Details"]);
dvDropDown = dvm.CreateDataView(ds.Tables["Products"]);
}
private void InitLookUp() {
// Bind the edit value to the ProductID field of the "Order Details" table;
// the edit value matches the value of the ValueMember field.
gridLookup.DataBindings.Add("EditValue", dvMain, "ProductID");
// Prevent columns from being automatically created when a data source is assigned.
gridLookup.Properties.View.OptionsBehavior.AutoPopulateColumns = false;
// The data source for the dropdown rows
gridLookup.Properties.DataSource = dvDropDown;
// 下拉框显示的字段数据.
gridLookup.Properties.DisplayMember = "ProductName";
// The field matching the edit value.
gridLookup.Properties.ValueMember = "ProductID";
// Add two columns in the dropdown:
// A column to display the values of the ProductID field;
GridColumn col1 = gridLookup.Properties.View.Columns.AddField("ProductID");
col1.VisibleIndex = 0;
col1.Caption = "Product ID";
// A column to display the values of the ProductName field.
GridColumn col2 = gridLookup.Properties.View.Columns.AddField("ProductName");
col2.VisibleIndex = 1;
col2.Caption = "Product Name";
// Set column widths according to their contents.
gridLookup.Properties.View.BestFitColumns();
// Specify the total dropdown width.
gridLookup.Properties.PopupFormWidth = 300;
}
2.3 GridControl
1、设计数据源并绑定字段:
DataTable dt = new DataTable();
dt.Columns.Add("name", System.Type.GetType("System.String"));
dt.Columns.Add("sex", System.Type.GetType("System.String"));
dt.Columns.Add("age", System.Type.GetType("System.String"));
DataRow row=dt.NewRow();;
row["name"] = "11";
row["sex"] = "ss";
row["age"] = "age";
dt.Rows.Add(row);
//绑定字段
gridView1.Columns[1].FieldName = "sex";
gridView1.Columns[2].FieldName = "age";
gridView1.Columns[0].FieldName = "name";
gridControl1.DataSource = dt;
2、 如何解决单击记录整行选中的问题
View->OptionsBehavior->EditorShowMode 设置为:Click
3、 如何新增一条记录
(1)、gridView.AddNewRow()
(2)、实现 gridView_InitNewRow 事件
4、如何解决 GridControl 记录能获取而没有显示出来的问题
gridView.populateColumns();
5、如何让行只能选择而不能编辑(或编辑某一单元格)
(1)、View->OptionsBehavior->EditorShowMode 设置为:Click
(2)、View->OptionsBehavior->Editable 设置为:false
6、如何禁用 GridControl 中单击列弹出右键菜单
设置 Run Design->OptionsMenu->EnableColumnMenu 设置为:false
7、如何隐藏 GridControl 的 GroupPanel 表头
设置 Run Design->OptionsView->ShowGroupPanel 设置为:false
8、如何禁用 GridControl 中列头的过滤器 过滤器如下图所示:
设置 Run Design->OptionsCustomization->AllowFilter 设置为:false
9、如何在查询得到 0 条记录时显示自定义的字符提示/显示 如图所示:
方法如下:
//When no Records Are Being Displayed
private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)
{
//方法一(此方法为GridView设置了数据源绑定时,可用)
ColumnView columnView = sender as ColumnView;
BindingSource bindingSource = this.gridView1.DataSource as BindingSource;
if(bindingSource.Count == 0)
{
string str = "没有查询到你所想要的数据!";
Font f = new Font("宋体", 10, FontStyle.Bold);
Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5);
e.Graphics.DrawString(str, f, Brushes.Black, r); }
//方法二(此方法为GridView没有设置数据源绑定时,使用,一般使用此种方 法)
if (this._flag)
{
if (this.gridView1.RowCount == 0)
{ string str = "没有查询到你所想要的数据!"; Font f = new Font("宋体", 10, FontStyle.Bold);
Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);
e.Graphics.DrawString(str, f, Brushes.Black, r); } } }
10、如何显示水平滚动条
设置 this.gridView.OptionsView.ColumnAutoWidth = false;
列表宽度自适应内容
gridview1.BestFitColumns();
11、如何定位到第一条数据/记录?
设置 this.gridView.MoveFirst()
12、如何定位到下一条数据/记录? 设置 this.gridView.MoveNext()
13、如何定位到最后一条数据/记录?
设置 this.gridView.MoveLast()
14、设置成一次选择一行,并且不能被编辑
this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;
this.gridView1.OptionsBehavior.Editable = false;
this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;
15、如何显示行号? private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) { e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far; if (e.Info.IsRowIndicator) { if (e.RowHandle >= 0) { e.Info.DisplayText = (e.RowHandle + 1).ToString(); } else if (e.RowHandle < 0 && e.RowHandle > -1000) { e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite; e.Info.DisplayText = "G" + e.RowHandle.ToString(); } } }
16、如何让各列头禁止移动?
设置 gridView1.OptionsCustomization.AllowColumnMoving = false;
17、如何让各列头禁止排序?
设置 gridView1.OptionsCustomization.AllowSort = false;
18、如何禁止各列头改变列宽?
设置 gridView1.OptionsCustomization.AllowColumnResizing = false;
19.拖动滚动条时固定某一列
设置Columns,选择要固定的列。设置Fixed属性,可以选择:固定在左边、固定在右边、不固定。 |
20.获取选定行,指定列单元格的内容
return gridView1.GetRowCellValue(pRows[0], ColumName).ToString ();
21.分组显示
OptionsView>OptionsBehavior>AutoExpandAllGroups = True 选择要分组的列,将GroupIndex属性设置为0
22.格式化数据
private void gvList_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e) { if (this.gvList.FocusedColumn.FieldName == "passQty") { string passQty = e.Value.ToString().Trim(); int receiveQty = orderDetailList[this.gvList.FocusedRowHandle].qty; if (!JXType.IsIntBigThanZero(passQty)) { e.Valid = false; e.ErrorText = "合格数量必须为大于等于0小于等于接货数量的整数!"; } else { if (int.Parse(passQty) > receiveQty) { e.Valid = false; e.ErrorText = "合格数量必须为大于0小于等于接货数量的整数!"; } } }
}
23.合并表头
界面操作:
代码操作如下:
示例代码1:
private DevExpress.XtraGrid.Views.BandedGrid.BandedGridView bandedGridView1;

示例代码2:
///初始化表格
using DevExpress.XtraGrid.Columns; using DevExpress.XtraGrid.Views.Base; using DevExpress.XtraGrid.Views.BandedGrid; using DevExpress.XtraEditors.Repository; private void InitGrid() { // advBandedGridView1是表格上的默认视图,注意这里声明的 是:BandedGridView BandedGridView view = advBandedGridView1 as BandedGridView; view.BeginUpdate(); //开始视图的编辑,防止触发其他事件 view.BeginDataUpdate(); //开始数据的编辑 view.Bands.Clear();
view.OptionsView.ShowColumnHeaders = false; //因为有Band列了,所以把ColumnHeader隐藏 //添加列标题 //添加列标题 GridBand bandID = view.Bands.AddBand("ID"); bandID.Visible = false; //隐藏ID列 GridBand bandName = view.Bands.AddBand("姓名"); GridBand bandSex = view.Bands.AddBand("性别"); GridBand bandBirth = view.Bands.AddBand("出生日期"); GridBand bandScore = view.Bands.AddBand("分数"); GridBand bandMath = bandScore.Children.AdBand("数学"); GridBand bandChinese = bandScore.Children.AddBand("语文"); GridBand bandEnglish = bandScore.Children.AddBand("英语"); GridBand bandSubTotal = bandScore.Children.AddBand("小计"); GridBand bandRemark = view.Bands.AddBand("备注");
bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//这是合并表头居中显示 view.EndDataUpdate();//结束数据的编辑 view.EndUpdate(); //结束视图的编辑 }
具体可看
dev gridcontrol 合并表头
24、 //动态添加列 DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn(); Col1.FieldName = "name"; Col1.Caption = "名字"; Col1.Visible = false; Col1.VisibleIndex = gvCountry.Columns.Count; gvCountry.Columns.Add(Col1);
25、设置自动增加的行号
private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) {
e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far; if (e.Info.IsRowIndicator) { if (e.RowHandle >= 0) { e.Info.DisplayText = (e.RowHandle + 1).ToString(); } else if (e.RowHandle < 0 && e.RowHandle > -1000) { e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite; e.Info.DisplayText = "G" + e.RowHandle.ToString(); } }
}
26、特效:gridcontrol中有5种view 型式,普通的是gridview,然后分别为cardview、BandedView、Advanced BandedView、LayoutView;共5种。
1)、view组中把OptionView下的viewmode 设置成“Carousel”就达到这种“旋转木马”式的gridcontrol view 特效了 2)、layoutView1.OptionsCarouselMode.PitchAngle 这个属性决定“旋转木马”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 倾角; 节锥半角 3)、Roll Angle 属性决定着 倾侧角度 4)、指定数据源,显示数据: //显示数据 private void showData(List<Employee > list) { DataTable dt = new DataTable("OneEmployee"); dt.Columns.Add("Caption", System.Type.GetType("System.String")); dt.Columns.Add("Department", System.Type.GetType("System.String")); dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));
for (int i = 0; i < list.Count; i++) { DataRow dr = dt.NewRow(); dr["Caption"] = list[i].Name; dr["Department"] = list[i].Department; string imagePath = @"D:\C#\photos\" + list[i].PhotoPath; dr["PhotoName"] = getImageByte(imagePath); dt.Rows.Add(dr); } gridControl1.DataSource = dt; }
//返回图片的字节流byte[] private byte[] getImageByte(string imagePath) { FileStream files = new FileStream(imagePath, FileMode.Open); byte[] imgByte = new byte [files.Length ]; files.Read(imgByte, 0, imgByte.Length); files.Close(); return imgByte; }
27、检查数据的有效性
在gridview的ValidateRow事件中加入检查代码: #region 检查数据 private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e) { GridView view = sender as GridView; view.ClearColumnErrors();
if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value) { e.Valid = false; view.SetColumnError(view.Columns["ReceiveDate"], "必须指定日期"); }
}
28、设某一列文字和标题局中显示 gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
29、列表过滤条件多选
列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList
30、隔行换色的方法
// 设置奇数行颜色,默认也是白色 可以省略
this.gridView1.Appearance.OddRow.BackColor = Color.White;
//使所以的奇数行能上面绑定 同时使用有效 this.gridView1.OptionsView.EnableAppearanceOddRow = true;
// 设置偶数行颜色 this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke;
//使所以的偶数行能上面绑定 同时使用有效 this.gridView1.OptionsView.EnableAppearanceEvenRow = true;
31、删除选中行,添加行
删除选中行通过DeleteSelectedRows()方法,可以通过AddNewRow()方法添加行;
具体示例代码如下:
if (gridView1.SelectedRowsCount > 0)
{
gridView1.DeleteSelectedRows();
}
32、设置只读属性
通过OptionColumn的readOnly属性,把某一列设置为只读属性;
this.gridView1.Columns[0].OptionsColumn.ReadOnly = true;
2.4 TreeList控件
树列表,该事件的AfterCheckNode事件是当选择CheckBox时所触发的事件;
示例代码:
/// <summary>
/// 实体类
/// </summary>
class PersonTo
{
public string Name
{
set;
get;
}
public string Age
{
set;
get;
}
}
//绑定数据源,添加节点
private void AddTreeNode()
{
ArrayList pl = new ArrayList();
PersonTo p = new PersonTo();
p.Name = "liu";
p.Age = "20";
pl.Add(p);
PersonTo p2 = new PersonTo();
p2.Name = "yu";
p2.Age = "21";
pl.Add(p2);
treeList1.DataSource=pl;
object[] s = new object[] { "1", "1", "1" };
object ss = new object();
this.treeList1.AppendNode(s,0);
}

// Initializing progress bar properties
progressBarControl1.Properties.Step = 1;
progressBarControl1.Properties.PercentView = true;
progressBarControl1.Properties.Maximum = fileEntries.Length;
progressBarControl1.Properties.Minimum = 0;
// Removing the list of files found in the specified directory
foreach(string fileName in fileEntries){
File.Delete(fileName);
progressBarControl1.PerformStep();
//进行再次重绘
progressBarControl1.Update();
}
}
}
// ...
DeleteFiles("d:\\Temp");
3.11 ImageListBoxControl
