推荐答案
将当前的html放入PlaceHolder元素，添加另一个placeHolder元素，并将进度控件放入其中.根据需要显示/隐藏每个.
Put your current html ino a PlaceHolder element, add another placeHolder element and put a progress control in it. Show/hide each as needed.
<asp:PlaceHolder ID="MyPage" runat="server" Visible="true" >
your existing content
<asp:PlaceHolder>
<asp:PlaceHolder ID="MyProgress" runat="server" Visible="false" >
<asp:ProgressBar />
<asp:PlaceHolder>
