    <ProgressTemplate>
    
        <div id="theprogress">

</asp:UpdateProgress>
</form>

考虑当按下btn1时，我想显示图像！该怎么办?

Consider that when btn1 is pressed i want to show the image!how can i do it?

推荐答案

应该将UpdateProgress控件与.在您的代码示例中，我没有看到UpdatePanel.请查看以下教程:

如果您只有1个更新面板，则还可以添加更新进度控件.因此，当在更新面板中进行部分回发时，将在部分更新完成后初始化并禁用更新进度控件.

但是，如果您有多个更新进度控件，则还必须指定AssociatedUpdatePanelID.

本教程将详细讨论所有这些内容.看看吧！

An UpdateProgress control is supposed to be used with an UpdatePanel. In your code sample, I don''t see an UpdatePanel. Check out the following tutorial:

http://msdn.microsoft.com/en-us/library/bb386421.aspx[^]

If you just have 1 update panel, you can also add a update progress control. So when a partial post-back occurs w/in the update panel, the update progress control will be initialized and disabled when the partial update is complete.

But, in case you have multiple update progress controls you also have to specify a AssociatedUpdatePanelID.

The tutorial discusses all of this in detail. Check it out!
