In vb:

Protected Overrides Sub OnViewStateExpire(ByVal e As
EventArgs)
'viewstate has expired
Me.RedirectToMobilePage("errorEvent.aspx?ref=viewstate")
End Sub

Hi Steph,

Now I am able to redirect the main page to the login page when session
expired with OnViewStateExpire. What if a user click the login button after
few minits and hit the session timeout again?

I just wonder why the new session is not created only when the user click
the login button?

I though by adding this

Hi Steph,

Now I am able to redirect the main page to the login page when session
expired with OnViewStateExpire. What to do if a user click the login button
(*after 1 min) and hit the session timeout again?

I just wonder why the new session is not created only when the user click
the login button? and How?

I though by adding Session.Abondon can solve the problem but it seems like
when I click the Login button (* after 1 min), the program still calling the
OnViewStateExpire and give me timeout message.

Protected Overrides Sub OnViewStateExpire(ByVal e As EventArgs)
Session.Abondon()
RedirectToMobilePage("MobileLogin.aspx?err=timeout")
End Sub

Currently I set the SessionTimeout to 1 for testing purpose.

tx,
Kenny

To catch a page error you can always use this:

Private Sub Page_Error(ByVal sender As Object, ByVal e As
System.EventArgs) Handles MyBase.Error
' Add some code here to log error if desired
Server.Transfer("CustomErrorPage.aspx")
End Sub

This will handle any errors in your page and redirect to an error
page. Before redirecting you could log the errors somewhere if you
want to see what it is but that way the user gets a nice friendly
page.
