Hi, 

I have implement a RadWindow to display the outcome of a process and there is a "ok" button in RadWindow to close it. 

When i click on the browser back button, the previous RadWindow  message will show out.

I like to know is there anyway to stop the RadWindow showing when users click on the browser 'back' button? 

How should i handle it?

Thank,

Hi,

This is, most likely, caused by the fact that the code that opens the RadWindow is called again when the page reloads. You would have to either raise some flags (e.g., cookies, session flags, whatever), or find another way to ensure the code does not get executed again. RadWindow itself does not monitor the browser, or the session, and with HTTP being stateless, such behavior is expected.
