Question

<telerik:RadGrid ID="RGStyleGuideRestrictions" runat="server" DataSourceID="SqlDataSource1"
                OnItemCommand="RGStyleGuideRestrictions_ItemCommand"

    <MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="TerritoryReportGroup">

      <Columns>
        <telerik:GridTemplateColumn UniqueName="TemplateColumn">
            <ItemTemplate>                
                <asp:ImageButton ID="imgBtn1" runat = "server"/> 
                <asp:ImageButton ID="imgBtn2" runat = "server"/>                     
            </ItemTemplate>
        </telerik:GridTemplateColumn>
      </Columns>
    </MasterTableView>
</telerik:RadGrid>

在CODE-BEHIND中： -

protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
{
   ImageButton imgBtn1 = e.item.FindControl("imgBtn1") as ImageButton;
   ImageButton imgBtn2 = e.item.FindControl("imgBtn2") as ImageButton;
}

问题： - 现在，点击任意一个ImageButton会触发ItemCommand事件。我想找出或获取代码隐藏中的ImageButton（1或2）的ID，它触发了ItemCommand。

请建议该怎么做。我不知道。

Answer 1

您是否尝试过将CommandNames应用于图像按钮？

 <asp:ImageButton ID="imgBtn1" runat = "server" CommandName="imgAction1"/> 
 <asp:ImageButton ID="imgBtn2" runat = "server" CommandName="imgAction2"/>

 protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
 {
      switch(e.CommandName)
      {
         case "imgAction1": // do stuff here
             break;
         case "imgAction2": // do some other stuff here
             break;
      }
 }

源对象是触发命令的对象。只需将源转换为图像按钮，然后检查是按钮1还是按钮2。

protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
{
   ImageButton fired = source as ImageButton;
   if(fired!=null && fired.Id=="imgBtn1")
   {
      //imgBtn1 fired the command
   }
   else 
   {
     // and so on...
   }
   ImageButton imgBtn1 = e.item.FindControl("imgBtn1") as ImageButton;
   ImageButton imgBtn2 = e.item.FindControl("imgBtn2") as ImageButton;
}

由于上述代码不起作用，请尝试以下方法：

  <telerik:GridTemplateColumn UniqueName="TemplateColumn">
        <ItemTemplate>                
            <asp:ImageButton CommandArgument="btn1" ID="imgBtn1" runat = "server"/> 
            <asp:ImageButton CommandArgument="btn2" ID="imgBtn2" runat = "server"/>                     
        </ItemTemplate>
    </telerik:GridTemplateColumn>


protected void RGStyleGuideRestrictions_ItemCommand(object source, GridCommandEventArgs e)
{

   if(e.CommandArgument=="btn1")
   {
      //imgBtn1 fired the command
   }
   else if(e.CommandArgument=="btn2")
   {
      //imgBtn2 fired the command  
   }
   ImageButton imgBtn1 = e.item.FindControl("imgBtn1") as ImageButton;
   ImageButton imgBtn2 = e.item.FindControl("imgBtn2") as ImageButton;
}
