you do one thing in log out button you directly swich to home page of application
and write the code ( webpage1.show)
i think its work you try and reply me

Use Session for that problem

you can either use AJAX using the Asp.Net Update Panel(search google)
or
use this code
Session.Abandon()
FormsAuthentication.SignOut()
if not Request.URLReferrer is nothing then
REFUrl = Request.URLReferrer.ToString
response.redirect(REFUrl) ' you can get the url referrer
else
response.redirect("default.aspx")
end if

Hope it helps,
