1. When the RibbonWindow is maximized the draggable area ends below the WindowTitle

2. In Normal state - the draggable area could be expanded in Material, Fluent and Crystal themes


A possible workaround is to change the WindowCaptionHeight property:

 var parameters = SystemParameters2.Current;
 parameters.GetType().GetProperty("WindowCaptionHeight").SetValue(parameters, SystemParameters2.Current.WindowCaptionHeight + 26, null);

Several galleries in collapsed state. Open rightmost so that its popup is outside wpf window.

Then resize the window so that gallery goes into large state. The height of the RibbonGallery is incorrect and smaller than expected.

Workaround is to set MinHeight to (for example 67) to all RibbonGalleries.

The popup is no properly sized when you have two or more monitors with different resolutions. This is replicable also if the DPI is higher than 100%.

To work this around you can create a custom ribbonview, get the content presenter of the popup and manually set its Width. Here is an example in code:

public class CustomRibbonView : RadRibbonView
{
	private ContentPresenter selectedTabContentPopup;

	public override void OnApplyTemplate()
	{
		base.OnApplyTemplate();
		this.selectedTabContentPopup = this.GetTemplateChild("SelectedTabContentPopup") as ContentPresenter;
	}

	protected override void OnMinimizedPopupStateChanged(RadRoutedEventArgs e)
	{   
		base.OnMinimizedPopupStateChanged(e);
		if (this.IsMinimizedPopupOpen)
		{
			this.selectedTabContentPopup.Width = this.ActualWidth;
		}
	}
}

Windows10 on two monitors, at least one of them is with higher DPI -125 , 150 %.

This leads to unexpected black gap (glitch) between the RibbonWindow TitleBar and Content.

Partial workaround is to set manually a margin on the WindowDecorator:

  private void RadRibbonWindow_Loaded(object sender, RoutedEventArgs e)
        {
                Grid windowDecorator = this.ChildrenOfType<Grid>().FirstOrDefault(x => x.Name == "MaximizedWindowDecorator");
                windowDecorator.Margin = new Thickness(0, -1, 0, 0);          
        }

Currently, RadRibbonView's OnApplyTemplate method can be called after adding the new tabs so that the group and tabs are redrawn correctly.

The default size is 9. If you change it the issue occurs. This brings a visual glitch in the window. The title text is resized but the titlebar is not.

Note: This is reproducible only if the DPI is larger than 100%.

To work this around manually set the size of the titlebar element.

private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    Grid windowDecorator = this.ChildrenOfType<Grid>().FirstOrDefault(x => x.Name =="MaximizeWindowDecorator");
    RibbonTitleBarPanel ribbonTitlePanel = this.ChildrenOfType<RibbonTitleBarPanel>().FirstOrDefault(x => x.Name == "RibbonTitleBarPanel");
    windowDecorator.RowDefinitions[0].Height = newGridLength(ribbonTitlePanel.ActualHeight);
}

When there are enough items in a RibbonBackstageItem for the ScrollBar to appear, it is clipped by the RadRibbonWindow's header.

Workaround:
1. Extract the templates for RadRibbonBackstage and ScrollViewer
2. Refer the new template for the ScrollViewer in the template for the RadRibbonBackstage.
3. Change the margin for the PART_VerticalScrollBar from 0, -1, -1, -1 to 0, 27, -1, -1.
4. Set the new ControlTemplate to the RadRibbonBackstage in the application.

Reproduces when you add the ContextualGroups in code-behind. While resizing the RibbonWindow the Ribbon Title overlaps the ContextualGroup Header.

This is reproducible only if the ribbon window chrome is enabled (IsWindowsThemeEnabled=False).


You can resolve this by registering an input binding for the Alt+Space key gesture and attaching it to the Telerik.Windows.Controls.RibbonView.Shell.SystemCommands.ShowSystemMenuCommand RoutedUICommand.

static MainWindow()
{
     var keyBinding = new KeyBinding(Telerik.Windows.Controls.RibbonView.Shell.SystemCommands.ShowSystemMenuCommand, new KeyGesture(Key.Space, ModifierKeys.Alt));
     CommandManager.RegisterClassInputBinding(typeof(RadRibbonWindow), keyBinding);
     RadRibbonWindow.IsWindowsThemeEnabled = false;
}

The designer of VS crashes with a "Key cannot be null" when custom markup extension is used in Style Setter. This reproduces in the sample app attached in the blog (http://www.telerik.com/blogs/bring-office-2016-inspired-style-to-your-app-with-ui-for-wpf) on the TextBlock of the RabRadioButton HeadingStyle (snapshot attached) if you open MainWindow in Designer. Runtime everything works as expected.

Initially RibbonView gets rendered design-time. Trying to edit RibbonTab-s or add new one causes the whole control to dissapear in the designer. Clean and rebuild of the solution doesn't help -- cleaning the Shadow cache of Visual Studio Designer is the onliest thing that helps.

The issue reproduces with Class Library containing the Ribbon setup and IsWindowsThemeEnabled property of RibbonWIndow turned off (default value).

This is reproducible only if the application that holds RadRibbonView is started on another machine and you are connected to it through Remote Desktop Connection. When the keytips are enabled and you click in the main machine, then click inside the remote desktop window, the keytips are displayed.

As a workaround set a Margin="0,0,1,0" to the RadBibbonView in order to have the functionality working in the area of the RadRibbonView.
