Currently, the RadWindow control does not provide an API to achieve the wanted result, because this behavior comes from the native Window class, and it will be quite hard to modify. However, you could use the approach specified in this article. More specifically, subscribe to the HostCreated event of the Window control, and inside of it, set the SourceInitialized event of the HostWindow property provided by the HostWindowCreatedEventArgs event arguments. And finally, add the additional code from the provided article. MainWindow partial class should look as follows:
This will prevent the window from maximizing on double-click but it will retain its ability to drag and resize, and also, to get maximized from the maximized button.
That said, I have attached a sample project that implements this approach, so, could you give it a try? Also, if this is not the expected behavior, could provide a bit more information about what the expected result is?
