Hello Rahul,
I am not quite sure that I understand your scenario, but I think that you want to hide the browser window when a
RadWindow is opened. If this is your requirement, it is an impossible scenario because the
RadWindow control is based on an IFRAME and it behaves just like an IFRAME - cannot persist outside of the browser window. In your case, however you can make the
RadWindow modal and set a not transparent overly. This will hide the parent page's content and you can achieve it by overriding the
TelerikModalOverlay CSS class as follows:
I believe that
this page will be helpful in order to open the
RadWindow. Also, you can close the RadWindow control by using its client-side API described in
this help page.
I hope this helps.
Sincerely yours,
Fikret Mustafa
