一直想做这样的效果，实现的方法虽然不是很好，但效果还是出来了
<script runat="server"> /// <summary> /// 当Button2被点击，实际是Button3触发事件，这样就可以达到提交事件时禁用被提交的按钮效果 /// </summary> protected void Button_Click(object sender, EventArgs e) { System.Threading.Thread.Sleep(5000); Page.ClientScript.RegisterStartupScript(this.GetType(), "TorunTrigger", "StartBtn()", false); } </script> <script type="text/javascript"> function OffBtn() { //当Button2被禁用后，Button2的后台事件就不会被执行了， document.getElementById("Button2").disabled = true; document.getElementById("Button3").click(); return true; } function StartBtn() { document.getElementById("Button2").disabled = false; } </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head1" runat="server"> <title>UpdateProgress Example</title> <style type="text/css"> #UpdatePanel1, #UpdatePanel2, #UpdateProgress1 { border-right: gray 1px solid; border-top: gray 1px solid; border-left: gray 1px solid; border-bottom: gray 1px solid; } #UpdatePanel1, #UpdatePanel2 { 200px; height: 200px; position: relative; float: left; margin-left: 10px; margin-top: 10px; } #UpdateProgress1 { 400px; background-color: #FFC080; bottom: 0%; left: 0px; position: absolute; } </style> </head> <body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <asp:UpdatePanel ID="UpdatePanel2" UpdateMode="Conditional" runat="server"> <ContentTemplate> <%=DateTime.Now.ToString() %> <br /> <asp:Button ID="Button2" runat="server" Text="Refresh Panel" OnClientClick="return OffBtn()" /> <div style="display: none;"> <asp:Button ID="Button3" runat="server" OnClick="Button_Click" /> </div> </ContentTemplate> </asp:UpdatePanel> <asp:UpdateProgress ID="UpdateProgress1" runat="server"> <ProgressTemplate> Update in progress... </ProgressTemplate> </asp:UpdateProgress> </div> </form> </body> </html>
效果：
