Thanks Rob,

How do I do this? I've tried to add this button style definition into the APP.xaml, but I dont know how to make this onfocus only...

Code:
    <Application.Resources>
        <local:Datasources x:Key="AppDatasources" />
        <!-- added local reference to SilverlightAccessiblity (self)
        Set Local:datasources
        -->
        
        <Style x:Name="BorderStyle" TargetType="Button">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Border BorderBrush="Fuchsia"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
Also, when I then try to apply this style on by button on the xaml I get "The property style was not found in type button"

<Button Content="press me" Grid.Row="2" style="{StaticResource Borderstyle}">
<interactivity:Interaction.Behaviors>
<behaviors:ScrollOnFocusBehavior/>
</interactivity:Interaction.Behaviors>
</Button>


Sorry, I have limited understanding of the fundamentals here. Could you explain where and how I should be pointing the controls to a style template and how I can just affect the onfocused border.

Thanks
Bob
