Description

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

Solution

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:

• XAML

<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... --> 
 
            </telerikRibbonViewPrimitives:RibbonTitleBarPanel> 
 
            <!-- The new separator --> 
            <Rectangle x:Name="TitleBarSeparator" Grid.Row="1" Grid.ColumnSpan="3" VerticalAlignment="Top" Height="2" Fill="#80FFFFFF" Visibility="Collapsed"/> 
 
            <!-- Omitted code... --> 
        </Grid> 
        <!-- Omitted code... --> 
    </Grid> 
    <ControlTemplate.Triggers> 
        <!-- Omitted code... --> 
 
        <!-- The trigger for the newly added TitleBarSeparator --> 
        <MultiDataTrigger> 
            <MultiDataTrigger.Conditions> 
                <Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsHostedInRibbonWindow, FallbackValue=False}" Value="True" />
