Default Message box in ASP.NET

Hi, to all the users. I want to use a message box in ASP.NET web app such that when he clicks a logout button and message prompts to ask him do he really want to logout. I embedded javascript in with VB.NET but it won't works. Can anyone give suggestion for the same..

private Sub ShowMessage(dim message as String)
   MessageBox Script
   Dim scriptString As String = "<script language=JavaScript>"
   String scriptString = "<script language=JavaScript>";
   scriptString += "alert('" + message + "')"
   scriptString += "</script>"
   Page.RegisterStartupScript("ShowMessage", scriptString)
   End Sub
   Private Sub imgLoggedout_Click(ByVal sender As System.Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles imgLoggedout.Click
   ShowMessage("Do you really want to logout")
   'MsgBox("Do you really want to logout", MsgBoxStyle.OKCancel = MsgBoxStyle.OKOnly, Session("userlogedin") = "No")
   Session("userlogedin") = "No"
End Sub

You can do this like this:

Somewhere in your page so it always runs (maybe Page_Load()) add this code:

imgLoggedout.Attributes("onclick") = "return confirm('Do you really want to log out?');"

This will fire off the "confirm" client side method which gives you the OK/Cancel dialog. If the user hits cancel, the page is not posted and thus the logout code on the server doesn't run.

ya it works, the message box is displayed. But on clicking ok button it is redirecting to the same page. I want it to redirect to logon.aspx page which is the default page of my web application.
