Glowing WPF Buttons

Question

After clicking the WPF buttons in our app they glow blue, back to original color, back to blue, etc. This appears to be default behavior on Windows Vista/7. It does not happen on XP. Any advice?

Answer 1

You need to override the ControlTemplate. Otherwise it's using triggers to set the colors on events like hovering the mouse over it. If you simply set the Background, you're only setting the default background when there's no Triggers going on.

Answer 2

You need to override the default button template -- http://mark-dot-net.blogspot.com/2007/07/creating-custom-wpf-button-template-in.html should get ya started.

Specifically Section 3:

<ControlTemplate.Triggers>
    <Trigger Property="IsMouseOver" Value="True">
        <Setter TargetName="border" Property="BorderBrush" Value="#FF4788c8" />
        <Setter Property="Foreground" Value="#FF4788c8" />
    </Trigger>
    <Trigger Property="IsPressed" Value="True">                   
       <Setter Property="Background" >
           <Setter.Value>
               <LinearGradientBrush StartPoint="0,0" EndPoint="0,1" >
                   <GradientStop Color="#FFFFD190" Offset="0.35"/>
                   <GradientStop Color="Orange" Offset="0.95"/>
                   <GradientStop Color="#FFFFD190" Offset="1"/>
               </LinearGradientBrush>
            </Setter.Value>
        </Setter>
        <Setter TargetName="content" Property="RenderTransform" >
            <Setter.Value>
                <TranslateTransform Y="1.0" />
            </Setter.Value>
        </Setter>
    </Trigger>
    <Trigger Property="IsDefaulted" Value="True">
       <Setter TargetName="border" Property="BorderBrush" Value="#FF282828" />
    </Trigger>
    <Trigger Property="IsFocused" Value="True">
       <Setter TargetName="border" Property="BorderBrush" Value="#FF282828" />
    </Trigger>
    <Trigger Property="IsEnabled" Value="False">
       <Setter TargetName="border" Property="Opacity" Value="0.7" />
       <Setter Property="Foreground" Value="Gray" />
   </Trigger>
</ControlTemplate.Triggers>
