datalist1嵌套datalist2 ，datalist2裡面按鈕點擊擷取datalist2裡label的值

 第1種方法

在頁按鈕加個CommandName並綁定

如：

前台

  <asp:ImageButton ID="ImageButton7" runat="server" Height="20px"
                                                      ImageUrl="~/image/yuding.gif" onclick="ImageButton7_Click" Width="50px"   

                                                       CommandName="CId" 
                    CommandArgument='<%# Eval("CId") %>' />

後台：

//注釋DataList2是第二個datalist

   protected void DataList2_ItemCommand(object source, DataListCommandEventArgs e)
       {
           if (e.CommandName == "CId")
           {
               string CId = e.CommandArgument.ToString();
          response.redirect("");
           }

}

 

 

 第2種方法

 

   protected void ImageButton7_Click(object sender, ImageClickEventArgs e)
       {
           DataList da = (DataList1)Dstlist.Items[0].FindControl("DataList2");
           Label lbl = (Label)da.Items[0].FindControl("Lblcid");
           lbl.Text = "123";

       }
