Storyboards in ResourceDictionary
So I would like to move my Storyboards into a ResourceDictionary file and I am having trouble doing that. I have looked everywhere and it involves making the "Resource" sharable but how do I do that in silverlight when there is no x:Shared attribute. Here is the code
<Storyboard x:Key="GreenButtonLight" > <ColorAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="GreenBelow" Storyboard.TargetProperty="(Shape.Fill).(GradientBrush.GradientStops).(GradientStop.Color)"> <SplineColorKeyFrame KeyTime="00:00:00" Value="#FF75F45D" /> <SplineColorKeyFrame KeyTime="00:00:00.1000000" Value="#FFA5F796" /> <SplineColorKeyFrame KeySpline="1,0,1,0.06" KeyTime="00:00:00.5000000" Value="#FF75F45D" /> </ColorAnimationUsingKeyFrames> </Storyboard>
Here is what i have in XAML
<Grid.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources/ViewResources.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Grid.Resources>
and here is the Error That i get
Error: Element is already the child of another element.
It only gives me that error when I put in storyboards, nothing else (ex:Styles). I am using Silverlight 3 and not wpf.
You can't place a storyboard in a resource because its a stateful object. It knows whether it has begun animating, where it is in the timeline etc. Also its child animations acquire a references to the objects and properties they are animating.
Typically one places storyboards to be reused in the VisualStateManager of an element in control template.
