Question

我想通过 DataList 中的按钮单击事件来更改按钮的状态。请在这方面帮助我。

<asp:DataList ID="DataList1" CaptionAlign="Right" runat="server" Width="100%" Visible="true">
      <ItemTemplate>
            <table style="border-bottom:0px; border-left:0px; border-right:0px;" width="100%"  border="0" cellspacing="0" cellpadding="0">                                                                            
              <tr>
                  <td width="120px"><asp:Label ID="lbl_ccode" runat="server" Text='<%#Bind("Fld_Couponcode")%>' ></asp:Label></td>
                  <td width="140px"><asp:Label ID="lbl_cval" runat="server" Text='<%#Bind("Fld_CouponValue")%>' ></asp:Label></td>
                  <td width="140px"><asp:Label ID="bl_status" runat="server" Text='<%#Bind("fld_status")%>' ></asp:Label></td>
                  <td width="140px"><asp:Button ID="btnstatus" runat="server" Text='<%#Bind("fld_status")%>' /></td>
             </tr>                                                                                                 </table>
      </ItemTemplate>
      <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />

处理DataGrid.ItemCommand 事件

在 DataGrid 控件中单击任何按钮时发生。

<asp:Button ID="btnstatus" CommandName="ChangeStatus" 
runat="server" Text='<%#Bind("fld_status")%>' />

  void ItemsGrid_Command(Object sender, DataGridCommandEventArgs e)
  {

     switch(((Button)e.CommandSource).CommandName)
     {

        case "ChangeStatus":

         // Add your code here

           break;

        default:
           // Do nothing.
           break;

     }

  }
