I would like to skin a wpf default checkbox to something custom. Since it does not really make sense to start off a entirely new control, i'd like to override the Windows Chrome template binding for the Bulletchrome sub component of the checkbox. However I cannot do this like I can with checkboxes for example. tried using something like this to override the default style, but it seems to not compile like this <Style x:Key="cb_BULLETSTYLE" TargetType="{x:Type BulletDecorator}"> <Setter Property="OverridesDefaultStyle" Value="true"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type BulletDecorator}"> <Border x:Name="Chrome" SnapsToDevicePixels="true" BorderBrush="{x:Null}" BorderThickness="0"> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Background" TargetName="Chrome" Value="#FF4C4C4C"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter>
