Developer Express XtraGrid使用技巧

1.基本grid的用法

1.1 gridControl-->view-->gridView

绑定到grid上的字段可以拖动删除,在任意字段上右键点column chooser 可以将删除的字段添加进来

字段上右键选择实现选定需要的信息和排序

字段上右键选择分组(group by   column),也可以直接将字段拖到上面实现分组

字段上右键选择group by box后可以取消分组栏,(不能实现拖动分组,但可以选择分组)

字段上右键选择best fit可以实现该字段最佳宽度(便于查看)

1.2 gridControl-->view-->cardView

以卡片形式存放数据

可以自己设定过滤选项

1.3 gridControl-->view-->banderGridView

将字段分段显示,前提是给gridControl先绑定一个dataset

动态绑定的时候不能分段,也不能分行

1.3 gridControl-->view-->advBanderGridView

高级分段显示,动态绑定的字段可以在前台向下拖动后分段,但效果不好,相当于分行显示的样子

1.4 else

可以通过create ner view增加一个view ,但程序只显示你选定的view

zoom的使用   快速上升,也就是选择子项后单独显示(上到最高显示)

1.5 feature browser

-->priview   可以指定在每行中预览的字段

-->filtering 可以自动过滤(optingview.showAutoFiterRow)

1.7 Master-Detail 绑定的问题
首先在gridControl1中指定dataSource 的绑定是主表
然后在level设计器中添加层(retrieve details)
最后用代码绑定:
using (SqlConnection con = new SqlConnection(SqlHepler.CONN_STRING))
             {
                 //SqlDataAdapter sda1 = new SqlDataAdapter("select * from Orders",con);
                 //sda1.Fill(this.northwindDataSet.Orders);

                 SqlDataAdapter sda2 = new SqlDataAdapter("select * from [Order Details]",con);
                 sda2.Fill(this.northwindDataSet.Order_Details);
             }

1.8 summary的用法

             //If the GridOptionsView.ShowFooter option is set,
             //the summary(of course some else can ) can be displayed within the footer cell.
             gridView1.OptionsView.ShowFooter = true;

             //初始化,也可以不用指定
             colOrderID.SummaryItem.FieldName = "OrderID";
             colOrderID.SummaryItem.SummaryType = DevExpress.Data.SummaryItemType.Count;

2.XtraGrid的打印

借用别人写的一个类

class DevPrint
     {

         //*********************字段*********************
         private string pageHeaderName="";
         private string pageFooterName="";
         private bool isPrintPage=true;
         private bool isPrintDate=true;

         private System.Drawing.Font pageFooterFont = null;
         private System.Drawing.Printing.Margins devMargins = null;
         private System.Drawing.Printing.PaperKind devPaperKind = System.Drawing.Printing.PaperKind.A4;//可以自定义修改纸张
         private DevExpress.XtraPrinting.PageHeaderArea PHA = new DevExpress.XtraPrinting.PageHeaderArea();
         private DevExpress.XtraPrinting.PageFooterArea PFA = new DevExpress.XtraPrinting.PageFooterArea();
         //*********************字段*********************
