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!";

Rectangle r = new Rectangle(e.EditViewInfo.ContentRect.Left,
e.EditViewInfo.ContentRect.Top,
Convert.ToInt32(e.Graphics.MeasureString(e.CellText, treeList1.Font).Width + 1),
Convert.ToInt32(e.Graphics.MeasureString(e.CellText,treeList1.Font).Height));
e.Graphics.FillRectangle(SystemBrushes.Highlight, r);
e.Graphics.DrawString(e.CellText, treeList1.Font, SystemBrushes.HighlightText, r);
e.Handled = true;
}
}
//============================================================================
//===============================以下内容为收集===============================
//============================================================================
一、改变grid的样式。
DevExpress.XtraGrid.Design.XAppearances xapp;
xapp=new DevExpress.XtraGrid.Design.XAppearances(System.Environment.GetFolderPath(System.Environment.SpecialFolder.System) + "\\DevExpress.XtraGrid.Appearances.xml ");
xapp.LoadScheme(“样式名字”, gridControl1.MainView);
二、选择单元设置和取所选的值
gridView1.OptionsSelection.MultiSelect = ceMultiSelect.Checked; //多行选择
gridView1.OptionsSelection.MultiSelectMode= GridMultiSelectMode.CellSelect;
gridView1.OptionsSelection.MultiSelectMode= GridMultiSelectMode. RowSelect; //
三、gridview的控制
///<取当前选中的值>
string GetSelectedRows(GridView view) {
string ret = "";
int rowIndex = -1;
if(view.OptionsSelection.MultiSelectMode == GridMultiSelectMode.RowSelect) {
foreach(int i in gridView1.GetSelectedRows()) {
DataRow row = gridView1.GetDataRow(i);
if(ret != "") ret += "\r\n";
ret += string.Format("Company Name: {0} (#{1})", row["CompanyName"], i);
}
}
else {
foreach(GridCell cell in view.GetSelectedCells()) {
if(rowIndex != cell.RowHandle) {
if(ret != "") ret += "\r\n";
ret += string.Format("Row: #{0}", cell.RowHandle);
}
ret += "\r\n " + view.GetRowCellDisplayText(cell.RowHandle, cell.Column);
rowIndex = cell.RowHandle;
}
}
return ret;
}
///<设置选中的颜色>//半透明的效果
private void icbTranslucentColors_CheckedChanged(object sender, System.EventArgs e) {
if(icbTranslucentColors.Checked) {
gridView1.Appearance.SelectedRow.BackColor = Color.FromArgb(30, 0, 0, 240);
gridView1.Appearance.FocusedRow.BackColor = Color.FromArgb(60, 0, 0, 240);
}
else {
gridView1.Appearance.SelectedRow.Reset();
gridView1.Appearance.FocusedRow.Reset();
}
}
///<自动添加一行>
gridView1.OptionsView.NewItemRowPosition = NewItemRowPosition.Bottom//Top/None;
///<设置gridView的按钮>
gridView1.ShowButtonMode = ShowButtonModeEnum.。。。。。。
gridView1.OptionsBehavior.Editable = chEdit.Checked; //设置按钮是否可用
///向选中的空间输入字符串
SendKeys.Send(“fsfds”);
///控件焦点
gridControl1.Focus();
四、cardView的设置
///是否现实快捷按钮CustomizeButton
cardView1.OptionsView.ShowQuickCustomizeButton=true/false;
///设置CustomizeButton的能否排序和过滤
foreach(GridColumn col in cardView1.Columns)
{ col.OptionsColumn.AllowSort}
foreach(GridColumn col in cardView1.Columns)
{ col.OptionsFilter.AllowFilter}
///card的头上的ico显示
cardView1.LayoutChanged();
///card的头上的标题改变显示
cardView1.CardCaptionFormat =””;
///cardview显示的单个记录的折叠按钮
cardView1.OptionsView.ShowCardExpandButton=true;
///
cardView1.MaximumCardColumns =iSize
cardView1.MaximumCardRows = val;
cardView1.OptionsBehavior.AutoHorzWidth
///多选
cardView1.OptionsSelection.MultiSelect = ceMultiSelect.Checked;
foreach(int i in cardView1.GetSelectedRows()) {
DataRow row = cardView1.GetDataRow(i);
if(ret != "") ret += "\r\n";
ret += string.Format("{0} / {1} : {2:$#,0.00}", row["Trademark"], row["Model"], row["Price"]);
}///查看选择中的记录
CellMerging(单元格合并的效果)
///
CellMerging(单元格合并的效果)
gridView1.OptionsView.AllowCellMerge = ceMerging.Checked;
Fixed Bands(bandedGridView)
///两边固定
gridBand3 的一列的Fixed属性改成 Right,Left,None
///固定与非固定列之间的距离用
bandedGridView2.FixedLineWidth = (int)numFixedLineWidth.Value;
///设置列的颜色
l 打开Run Designer 选中Columns 选中要改变的列 里面有AppearanceCell （设置列的外观）和 AppearanceHeader（设置表格头的外观）
l 或者选中该列查看“属性”里面也有这两个属性。
///统计 （gridView bandedGridView通用）
分组统计和全部统计：
全部统计：在最下面显示统计的结果。
Run Designer->Total Summary //->General 设置显示
//->Columns 对特定列来设置统计
汇总结果是否显示：可以通过gridControl的view的ShowFooter属性来设置表格下面的汇总结果
分组统计：
以上就是“分组”的显示在每个分组下面来显示汇总结果。
通过bandedGridView2.GroupFooterShowMode= GroupFooterShowMode.。。。。设置分组的显示模式。
///GridView设置菜单
#region Grid events
private void gridView1_ShowGridMenu(object sender, DevExpress.XtraGrid.Views.Grid.GridMenuEventArgs e) {
if(e.MenuType == DevExpress.XtraGrid.Views.Grid.GridMenuType.Column) {
