如果您希望在用户点击btn_Add_Task按钮时显示模态弹出窗口，则应将该按钮设置为扩展程序的TargetControlID：
<cc1:ModalPopupExtender ID="btn_Add_Task_ModalPopupExtender" runat="server"
TargetControlID="btn_Add_Task" PopupControlID="pnl_Add_Task"
BackgroundCssClass="modalBackground" DropShadow="True" />
在您当前的代码中，模式弹出窗口由名为Dummy_btn的按钮触发，我在您的标记中找不到，但可能不是您想要的。

我们在ajax popup中遇到了很多问题。你可能想尝试我们过去一个月左右使用的方法，没有任何问题。这种方法创建了一个不需要ajax / jquery / javascript / css / update面板的弹出窗口。
