    <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="Test.WebForm1" %>
    
    <!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">

    Hello,

    Use of a DirectMethod should help, see samples in the Examples Explorer:

    Thanks Geoffrey,

    I revised the code like these:

    <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="Test.WebForm1" %>
    
    <script runat="server">
        <DirectMethod>
        public sub SetTimeStamp()
            open_page()
        End Sub
    </script>
    
    <!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>test</title>
        <script type="text/javascript">
            var Confirm = function () {
                var title = 'Confirm';
                var msg = 'Are you sure?';
    
                Ext.Msg.confirm(title, msg, function (btn) {
                    if (btn == 'yes') {
                        SetTimeStamp();
                        return true;
                    } else {
                        return false;
                    }
                });
            }
        </script>
    </head>
    <body>
        <form id="form1" runat="server">
        <div>
            <ext:ResourceManager ID="ResourceManager1" runat="server" EnableViewState="True" DisableViewState="False" />
            <ext:Button ID="button2" runat="server" Text="Test1" Icon="Disk" >
            <Listeners>
                <Click Handler="return Confirm();" />
            </Listeners>
            </ext:Button>
        </div>
        </form>
    </body>
    </html>
    and the code behind are:
    Imports Ext.Net
    
    Public Class WebForm1
        Inherits System.Web.UI.Page
    
        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    
        End Sub
    
        Public Sub open_page()
            Response.Redirect("~/WebForm2.aspx")
        End Sub
    
    End Class
    But still didn't work. need your advise please. thanks.
