Can't call a response redirection in a page callback?

Question

I get the following error when I leave my network inactive for some time

"Response.Redirect.cannot will be called in the page callback."

I store the user IDs in the session and during the loading of the page, which I check to see if the user ID exists, if not, then I redirect them to the login page.

I am using devexpress controls, how can I make redirection work?

Answer 1

Try using a property Response.RedirectLocationthat works during the callback.
