WindowsFormsHost inside RadWindow is not visible


Product Version 2019.1.220
Product RadWindow for WPF and Silverlight


WindowsFormsHost is not displayed when set as the content of a RadWindow control.


To display the content of the WindowsFormsHost you need to make the RadWindow control non-transparent. This can be achieved by setting the attached WindowInteropHelper.AllowTransparency property to False.

public App() 
    var window = new MainWindow(); 
    RadWindowInteropHelper.SetAllowTransparency(window, false);
