I came up with a hacky way of doing "hover" and "press" buttons in WPF recently. There are a couple of nice examples on the web, but I was looking for a way to do it purely through XAML. If there's a nicer way to do it through XAML (or if there are big drawbacks to this approach) please let me know.

So, here's what I did.

  1. For the button, create a button template (very easy to do in blend...) that has an image in it, and hard-code that image to use the default bitmap. I also hardcoded the size to the image size.
  2. Add triggers for the IsMouseOver and IsPressed events to change the image to the appropriate hover or pressed bitmaps
  3. Apply the template to the button.

Okay, so it's not very general in that it hardcodes the behavior for the specific button, but it was really cheap to do.

 XAML looks something like this: 

     <ControlTemplate TargetType="{x:Type Button}">
       <Border x:Name="Border" Padding="{TemplateBinding Padding}" VerticalAlignment="Stretch" BorderThickness="2,2,2,2" CornerRadius="5,5,5,5">
        <Image HorizontalAlignment="Right" x:Name="image" Width="24" Height="26" Source="prev_rest.png"/>
       <Trigger Property="IsMouseOver" Value="true">
        <Setter Property="Source" TargetName="image" Value="prev_hover.png"/>
       <Trigger Property="IsPressed" Value="true">
        <Setter Property="Source" TargetName="image" Value="prev_down.png"/>
