Vista - Bug: Opacity modifier doesn't work inside a datatrigger for an Image

Hi

The following style

<Style x:Key="VisaImageStyle" TargetType="{x:Type Control}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Control}">
<Image x:Name="Card"
Source="pack://application:,,,/Images/Visa.png" Width="30" Opacity="0.6"/>
<ControlTemplate.Triggers>
<DataTrigger Binding="{Binding Path=Payment.CardType}" Value="Visa">
<Setter Property="Opacity" Value="1" TargetName="Card"/>
<Setter Property="Width" Value="40" TargetName="Card"/>
<Setter Property="BitmapEffect" Value="{StaticResource
CardShadow}" TargetName="Card"/>
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Will properly add a drop shadow, modify the width of the image, but it
will not change the opacity of the image when the trigger is activated.

This is on the Feb CTP.

Hi Phillipe,
Can you remove the BitmapEffect and confirm if this still repros?

[There is a bug in Feb CTP that causes opacity to not update when
BitmapEffect is applied. This is fixed for the next release (Beta 2) though.]

Thanks!

You are correct. Removing the Bitmap effect fixes the problem. Any ideas
when Beta 2 will be out the door.

We are working on getting it out the door, the dates are not finalized though
(sorry ).
