IsMouseOver Trigger does not override Background Property

[Steven]

Hi,

Why my Trigger on the property IsMouseOver does not display a Red Background ?

<Style TargetType="telerik:RadButton">
  <Style.Triggers>
           <Trigger Property="IsMouseOver" Value="true">
               <Setter Property="Background" Value="Red"/>
           </Trigger>
       </Style.Triggers>
   </Style>

Should I override it ?
I am using the metro theme.

Regards,
S

Hello Steven,

The default ControlTemplate of the RadButton control defines a trigger that sets the background of the control while the mouse is over it. And since the ControlTemplate trigger is applied after the Style trigger you defined, the Red color isn't applied.

This is why if you need to change the default MouseOver background, you'll have to edit the ControlTemplate of the RadButton - you can find the ControlTemplate structure of the control here and you can follow this approach to change it.

All the best,
