WinForms Host is Not Rendering if The RadRibbonView Panel is Collapsible


Product Version 2023.2.718
Product RadRibbonView for WPF


The content of RadRibbonView is not visible when the control is minimizable and WindowsFormsHost is used.


To host WindowsFormsHost content in a WPF Window or Popup, you should disable its transparency, otherwise the WindowsFormsHost content won't get displayed.

private void RadRibbonView_Loaded(object sender, RoutedEventArgs e) 
    var ribbonView = (RadRibbonView)sender; 
    var popup = ribbonView.ChildrenOfType<Popup>().FirstOrDefault(x => x.Name == "TabContentPopup"); 
    if (popup != null) 
        popup.AllowsTransparency = false;
