In order to add new RadWindow
you should declare it in the code behind and call its Show
method to open it. Please see the Getting Started
article from our documentation for an example.
If you need to declare its content in XAML you should use RadWindow
as a User Control - you should create a new User Control and replace its declaration with RadWindow declaration. Afterwards in the code behind you only need to inherit from RadWindow
instead of UserControl
. For more detailed explanation please refer to the Use RadWindow as User Control
article from our documentation.
Hope this helps.
