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
