项目中遇到这个问题，因为按钮提交执行需要五到八秒，容易使用户误认为没有提交成功，导致多次点击按钮提交，最后导致出错。在网上找了下资料， 有的说不用服务器控件，或者自定义类，继承Button基类等等其他方法，终于找到了如下比较简单的解决方法。演示代码如下：
前台aspx页面
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="buttonsubmit._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
<script language="javascript" type="text/javascript">
function abc(object1)
{
object1.disabled=true; //变灰
__doPostBack(object1.name,""); //执行服务器端button1的click事件 这里特别要注意是
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox id= "TextBox1" style= "Z-INDEX:101;LEFT:8px;POSITION:absolute;TOP:8px " runat= "server">1</asp:TextBox>
<asp:Button id= "Button1"
style= "Z-INDEX:102;LEFT:8px;POSITION:absolute;TOP:40px " runat= "server"
Text="Button" onclick="Button1_Click"></asp:Button>
</div>
</form>
</body>
</html>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
<script language="javascript" type="text/javascript">
function abc(object1)
{
object1.disabled=true; //变灰
__doPostBack(object1.name,""); //执行服务器端button1的click事件 这里特别要注意是
object1.name 而不能是 object1.id, 因为页面可能含有母版页
} </script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox id= "TextBox1" style= "Z-INDEX:101;LEFT:8px;POSITION:absolute;TOP:8px " runat= "server">1</asp:TextBox>
<asp:Button id= "Button1"
style= "Z-INDEX:102;LEFT:8px;POSITION:absolute;TOP:40px " runat= "server"
Text="Button" onclick="Button1_Click"></asp:Button>
</div>
</form>
</body>
</html>
后台cs文件：
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
namespace buttonsubmit
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// 在此处放置用户代码以初始化页面
Page.ClientScript.GetPostBackEventReference(Button1,null); //这句很关键，有这句才能让客户端执行服务器端事件。
Button1.Attributes.Add("onclick", "abc(this);");
}
protected void Button1_Click(object sender, EventArgs e)
{
int k = 0;
for (int i = 0; i < 99999; i++)
{
for (int j = 0; j < 9999; j++)
k = 9;
}
this.TextBox1.Text = "2";
}
}
}
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;

using System.Xml.Linq;
namespace buttonsubmit
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// 在此处放置用户代码以初始化页面
Page.ClientScript.GetPostBackEventReference(Button1,null); //这句很关键，有这句才能让客户端执行服务器端事件。
Button1.Attributes.Add("onclick", "abc(this);");
}
protected void Button1_Click(object sender, EventArgs e)
{
int k = 0;
for (int i = 0; i < 99999; i++)
{
for (int j = 0; j < 9999; j++)
k = 9;
}
this.TextBox1.Text = "2";
}
}
}
需要说明的是刷新页面是否会造成重复提交没有去试验，有兴趣和时间的朋友可以研究一下。
