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 {
            width: 200px;
            height: 200px;
            position: relative;
            float: left;

            margin-top: 10px;
        }

        #UpdateProgress1 {
            width: 400px;
