Button控制PopupControlExtender，但为什么Button的onclick事件不响应了啊？
如题：
具体使用如下..
<asp:Button ID= "btnDelReceiver " runat= "server " Text= "... " OnClick= "btnDelReceiver_Click " />

<ajaxToolkit:PopupControlExtender ID= "PopupControlExtender2 " runat= "server " PopupControlID= "Panel3 " OffsetX= "20 "
Position= "Left " TargetControlID= "btnDelReceiver " BehaviorID= "ctl00_PopupControlExtender2 " DynamicServicePath= " " Enabled= "True " ExtenderControlID= " ">
</ajaxToolkit:PopupControlExtender>
此时btnDelReceiver_Click不响应，请问如何解决？
