How to: Use Triggers to Style a ComboBoxItem
This example shows how to use Trigger elements to style a ComboBoxItem.
This example creates a Style that changes the appearance of a ComboBoxItem in response to an event that is raised on the item. When you move the mouse over the ComboBoxItem the appearance of the control changes.
Example
<Style x:Key="Triggers" TargetType="{x:Type ComboBoxItem}">
<Style.Triggers>
<Trigger Property="ComboBoxItem.IsMouseOver" Value="true">
<Setter Property = "Foreground" Value="Red"/>
<Setter Property = "FontSize" Value="20"/>
<Setter Property = "FontFamily" Value="Arial Bold"/>
</Trigger>
</Style.Triggers>
</Style>
