How to: Style a Separator Used as a Menu Item

Separator controls inside Menu elements appear differently from Separator controls outside a Menu. When you create a Menu with a Separator, the control automatically applies the Style identified by the SeparatorStyleKey property. Styles are placed in resource dictionaries and are searched for by their keys. To change the Style of a Separator inside a Menu, you must use the SeparatorStyleKey property to create your new Style. The following example demonstrates this.

Example

<Style x:Key="{x:Static MenuItem.SeparatorStyleKey}" TargetType="Separator">
  <Setter Property="OverridesDefaultStyle" Value="true" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type Separator}">
        <Border Width="30" Height="4" Margin="4" Background="Red"/>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>
