protected void Page_Load(object sender, EventArgs e)
{
//.NET1.1
Button1.Attributes.Add("onclick", "this.disabled=true;" + this.GetPostBackEventReference(this.Button1));
//.NET 2.0以上
Button1.Attributes.Add("onclick", "this.disabled=true;" + this.ClientScript.GetPostBackEventReference(Button1, ""));
}
为了测试,我们可以建立一个页面,加入一个btnAdd按钮
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AddAndEditUser.ASPx.cs" Inherits="AddUser" %><html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>添加和编辑页面示例</title>
</head>
<body>
<form id="frmMain" runat="server">
<ASP:Button ID="btnAdd" runat="server" CssClass="INPUT-BUTTON-Save" OnClick="btnAdd_Click">
</ASP:Button>
</form>
</body>
</html>

}
可见当点击了按钮,需要等5秒钟按钮才能点击。即页面回发一后按钮才能用。这样可以有效的防止用户多次点击按钮,造成多次提交!
