    protected void Page_Load(object sender, EventArgs e)
    {
        this.GetPostBackEventReference(this.Button3);

        //保证 __doPostBack(eventTarget, eventArgument) 正确注册
        if (!IsPostBack)
        {
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            sb.Append("if (typeof(Page_ClientValidate) == 'function') " +
                        "{" +
                            "if (Page_ClientValidate() == false)" +
                                "{" +
                                    "return false; " +

                                "}" +
                        "}");

            //保证验证函数的执行
            sb.Append("if(window.confirm('are you sure?')==false) return false; ");

            //自定义客户端脚本
            sb.Append("disableOtherSubmit(); ");

            // disable所有submit按钮
            sb.Append(this.GetPostBackEventReference(this.Button3));

            Button3.Attributes.Add("onclick", sb.ToString());
        }
    }

    override protected void OnInit(EventArgs e)
    {
        // // CODEGEN: This call is required by the ASP.NET Web Form Designer. //
        InitializeComponent();
        base.OnInit(e);
    }

    /// the contents of this method with the code editor.

    {
        this.Button3.Click += new EventHandler(Button3_Click);
        this.Load += new System.EventHandler(this.Page_Load);
    }

    private void Button3_Click(object sender, System.EventArgs e)
    {
        System.Threading.Thread.Sleep(3000);
        Response.Write("Hello world!");
    }
