什么是隐藏更新面板的内容调用的UpdateProgress时，最简单的方法是什么？

What is the easiest way to hide the Contents of an Update Panel when the UpdateProgress is invoked?

推荐答案

下面是一个很好的例子这样使用 Ajax控件Toolki

Here is a nice example doing this using Ajax Control Toolki

<ajaxToolkit:UpdatePanelAnimationExtender ID="ae"
  runat="server" TargetControlID="up">
     <Animations>
        <OnUpdating> ... </OnUpdating>
        <OnUpdated> ... </OnUpdated>
    </Animations>
</ajaxToolkit:UpdatePanelAnimationExtender>

*  TargetControlID - ID of the UpdatePanel  whose updates are used to play the animations (this is also the default target of the animations)
* OnUpdating - Generic animation played as when any UpdatePanel begins updating
* OnUpdated - Generic animation played after the UpdatePanel has finished updating (but only if the UpdatePanel was changed)
