     <script>
            Ext.getDoc().on('keydown', function (e) {
                if (e.getKey() == e.ENTER) {
                    App.dircect.verycode();  //here I want to call btnLogin's click , how to do thanks.
                }
            });
      </script>
    
                   <ext:Button ID="btnLogin" runat="server" Text="登陆" Icon="Accept">
                        <DirectEvents>
                            <Click OnEvent="btnLogin_Click">
                                <EventMask ShowMask="true" Msg="正在验证..." MinDelay="500" />
                            </Click>
                        </DirectEvents>
                    </ext:Button>
    
    
     [DirectMethod]
            protected void verycode()
            {
                string u = this.txtUsername.Text;
                string p = this.txtPassword.Text;
                if (u == "admin" && p == "XXX")
                {
                    Session["user"] = "admin";
                    Response.Redirect("~/index.aspx");
                }
                else
                {
                    X.MessageBox.Alert("提示", "登陆失败").Show();
                }
            }
            protected void btnLogin_Click(object sender, DirectEventArgs e)
            {
                verycode();

    Hi @hdsoso,

    Welcome to the Ext.NET forums!

    You can use the following.
    App.btnLogin.fireEvent("click", btnLogin);
    Another approach is using a DirectMethod. With this approach you should replace the DirectEvent with a combination of the Button's Click Listener and a DirectMethod call. Then you will be able to call that DirectMethod from anywhere.
