推荐答案

您需要重新创建，重新绑定并将用户控件再次放置在占位符中.由于您是动态创建的，因此它本身不会保留在回发中.

重新创建并将其放回相同的占位符，也将还原控件的视图状态.因此，在事件发生之前(可能是在页面加载中)，请在占位符中重新加载Usercontrol.

You need to re-create, re-bind and place the user control again in the place holder. Since you created it dynamically, it won''t persist at postbacks by itself.

Re-creating and putting it back to the same placeholder, would restore the viewstates of the control too. So, before the event, probably in your page load, reload the Usercontrol in Placeholder.
