In Telerik UI for ASP.NET AJAX, the RadWindowManager is not mandatory to be present on the page in order to show a RadWindow. Using the RadWindowManager however, is still a convenient way to declare common properties for all RadWindow that will be created with it or are already declared in its Windows collection.
On the client-side, the RadWindowManager takes care of:
- creating and opening new windows
taking care of the radalert, radconfirm and radprompt dialogs - you must have a RadWindowManager control on your page in order to show these dialogs.
providing a reference to a RadWindow
group functions to allow RadWindows' manipulating at once (for example - minimizing, restoring or maximizing all RadWindows on the page)
