We are creating custom WPF controls (not user controls) for an XBAP application and we would like to add a storyboard animation to scale the control to be 110% of its original size when the mouse hovers over it. We've used Blend to create the storyboard and it compiles just fine...however, when we run, it does not animate up to 110%. I've read bits and pieces here and there that you can't do storyboard animations in XAML for custom controls. Does anyone know how to do this for custom controls fully in XAML?
Here is the XAML for our custom control:
<Style TargetType="{x:Type controls:ExitButton}">
<Style.Resources>
<Storyboard x:Key="OnMouseEnter">
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="{x:Null}" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="1"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.2000000" Value="1.1"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="{x:Null}" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)">
<SplineDoubleKeyFrame KeyTime="00:00:00" Value="1"/>
<SplineDoubleKeyFrame KeyTime="00:00:00.2000000" Value="1.1"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</Style.Resources>
