Product RadRibbonView for WPF


How to add a separator between the title and the ribbon of the RadRibbonWindow.


To customize RadRibbonView in order to separate its title from the tabs, follow the next few steps:

  1. Extract the default ControlTemplate for the theme of your choice by following the instructions of the Extracting Control Templates Manually from the Theme XAML File section of the [Editing Control Templates](/devtools/wpf/styling-and-appearance/styling-apperance-editing-control-templates article.
  2. In the extracted ControlTemplate look for the element with x:Name="RibbonTitleBarPanel".
  3. Add a Rectangle or Border with the thickness and colors of your choice.
  4. Add a trigger that will show the above separator element (Rectangle/Border) when the RibbonView is hosted in a RadRibbonWindow.

Refer to the following code snippet with the Office2016 theme applied to the control:

<ControlTemplate x:Key="RadRibbonViewTemplate" TargetType="telerik:RadRibbonView"> 
    <Grid x:Name="RootPanel"> 
        <!-- Omitted code... --> 
        <Grid x:Name="TopGrid"> 
            <!-- Omitted code... --> 
            <telerikRibbonViewPrimitives:RibbonTitleBarPanel x:Name="RibbonTitleBarPanel" Grid.ColumnSpan="3" Visibility="{TemplateBinding TitleBarVisibility}"> 
                <!-- Omitted code... --> 
            <!-- The new separator --> 
            <Rectangle x:Name="TitleBarSeparator" Grid.Row="1" Grid.ColumnSpan="3" VerticalAlignment="Top" Height="2" Fill="#80FFFFFF" Visibility="Collapsed"/> 
            <!-- Omitted code... --> 
        <!-- Omitted code... --> 
        <!-- Omitted code... --> 
        <!-- The trigger for the newly added TitleBarSeparator --> 
                <Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsHostedInRibbonWindow, FallbackValue=False}" Value="True" /> 
                <Condition Binding="{Binding RelativeSource={RelativeSource AncestorType=telerikRibbonView:RadRibbonWindow}, Path=IsWindowsThemeEnabled}" Value="False" /> 
                <Condition Binding="{Binding RelativeSource={RelativeSource AncestorType=telerikRibbonView:RadRibbonWindow}, Path=IsTitleVisible}" Value="False" /> 
            <Setter TargetName="TitleBarSeparator" Property="Visibility" Value="Visible" /> 
<Style TargetType="telerik:RadRibbonView" BasedOn="{StaticResource RadRibbonViewStyle}"> 
    <Setter Property="Template" Value="{StaticResource RadRibbonViewTemplate}" />
