我有一个包含转发器的usercontrol。在这个转发器中有一个ImageButton，当点击它时应该调用expand方法。但是，ImageButton没有触发任何东西，甚至没有触发PostBack。
usercontrol上的AutoEventWireUp设置为true。 Repeater ItemDataBound在Markup中设置。但即便如此，ImageButton仍然不会触发任何类型的动作。
根本不会发生射击的原因是什么？
以下是HTML标记：

答案 0 :(得分：0)
您的转发器位于更新面板内，因此请使用异步类型的触发器，如下所示：
<Triggers>
<asp:AsyncPostBackTrigger ControlID="imagebtn" EventName="CLICK" />
</Triggers>
并对转发器的代码进行一些更改......
<asp:ImageButton runat="server" ID="ImageColapseExpand" onclick="ImageColapseExpand_Click" CommandArgument='<%#DataBinder.Eval(Container, "DataItem.CSIValue")%>'
ImageUrl="~/Secure/Images/plus_big.gif" />
<b>
在后面的代码中创建一个click事件，如下所示：
protected void ImageColapseExpand_Click(object sender, ImageClickEventArgs e)
{
}
希望这对你有用......
