到目前为止给DataGrid添加Number列最简单方法

suppose DataGrid named dgCustomize, insert the following code to the first column.

< asp:TemplateColumn  HeaderText ="No." >
     < ItemStyle  HorizontalAlign ="Center" ></ ItemStyle >
     < ItemTemplate >
         < asp:Label  runat ="server"  Text ='<%#  dgCustomize.CurrentPageIndex*dgCustomize.PageSize+dgCustomize.Items.Count+1 % > '>
         </ asp:Label >
     </ ItemTemplate >
</ asp:TemplateColumn >
