[SOLVED] ColorAnimation bug

Postby Sesztak » Sat Sep 17, 2016 7:38 am

Dear JS-Support,

We got null reference exception with ColorAnimation.

Background: we would like to animate a button (with x:Name="buttonDoubleAnimationAndColorAnimationSample") background colour.

Code:
XAML:
<Page.Resources>
<Storyboard x:Key="PlayAnimationGo" x:Name="PlayAnimationNevGo" Duration="0:0:5" >
<ColorAnimation Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)"
From="Red" To="Green" Duration="0:0:5" />
</Storyboard>
</Page.Resources>

C# code behind:
Storyboard.SetTarget(PlayAnimationNevGo, buttonDoubleAnimationAndColorAnimationSample);
PlayAnimationNevGo.Begin();

Exception:
{"Value cannot be null.\r\nParameter name: key"}
StackTrace:

Please, confirm, that you can reproduce the issue.

Waiting for your kind reply,
