我做了一个用户控件，默认显示一个LinkButton，点击后弹出ModalPopupExtender的Panel，Panel中有一个Button，和DropDownList，用户从DropDownList中选择记录后，点击Button，将选中记录的名称赋值到LinkButton的Text属性。
控件放在页面中使用没有问题，放在TabContainer中使用，可以正常弹出Panel，但似乎无法触发Button的Click事件。哪位兄弟做过类似的应用，帮忙看一下，谢谢了！

另外我建议你将没用的代码删除掉,提取一个测试版本,这样代码会少一些,帮你找问题的人就会多一些.
请问你是怎样将控件放在 TabContainer 中的?另外,估计如果你把选择事件写成客户端代码,即写成js应该就没有问题了,部分代码如下:将
<asp:Button ID="btnSave" runat="server" Text="确定" OnClick="btnSave_Click" />
改成库户端Input
<input type="button" value="确定" onclick="test();" />
function test()
{
var obj=document.getElementById("<%=ddl.ClientID %>");
var str=obj.options[obj.selectedIndex].text;
document.getElementById("<%=lnkbtnSelect.ClientID%>").childNodes[0].nodeValue=str;
}
说明:
1.因TabContainer中用到了 ScriptManager,所以我的控件中没有加 ScriptManager
2.控件中用到的 StyleSheet.css，你安装完toolkit后自己的机器中能找到，放到同一目录下即可.
3.我的代码测试无任何问题，你的如果还是不行就找找别的原因.
控件代码如下:
