Retrieve Storyboard from Event

Question

I have a generic Storyboard defined in my XAML as follows:

<Storyboard Core:Key="GenericAnimation" Completed="OnStoryboardCompleted"/>

And in my code-behind as follows:

m_GenericAnimation = (Storyboard)Resources["GenericAnimation"];

Every Storyboard of my applications shares the same Completed event OnStoryboardCompleted. I would like to change a little bit the behavior of my event depending on the animation that is just being completed like so (pseudocode):

private void OnStoryboardCompleted(object sender, EventArgs e) { if (completedStoryboard == m_GenericAnimation) DoSomethingSpecific(); DoSomethingCommon(); }

How can I retrieve the currently completed Storyboard from sender? How can I correctly compare two Storyboard objects?

You can use the Name property on Storyboard:

<Storyboard x:Key="Storyboard1" Name="Storyboard1_Name"> <!-- ... --> </Storyboard> <Storyboard x:Key="Storyboard2" Name="Storyboard2_Name"> <!-- ... --> </Storyboard>

And then:

Storyboard sb1, sb2; public MainWindow() { InitializeComponent(); sb1 = (Storyboard)Resources["Storyboard1"]; sb2 = (Storyboard)Resources["Storyboard2"]; sb1.Completed += storyboard_Completed; sb2.Completed += storyboard_Completed; } void storyboard_Completed(object sender, EventArgs e) { string StoryBoardName = ((ClockGroup)sender).Timeline.Name; if (StoryBoardName == "Storyboard1_Name") { /* DoSomething(); */ } if (StoryBoardName == "Storyboard2_Name") { /* DoSomething(); */ } }
