Access WPF Storyboard in XAML from code-behind (C#)
At more than one time working with WPF I've wanted to create a generic Storyboard using Blend because it saves me time and gives me a nice time line type layout to create/tweak my Storyboard. What happens is when you save the Storyboard it's added to the Windows.Resources collection the XAML. In Silverlight you can access these Storyboard resources directly using their x:Name value. In WPF, however, you need to do it slightly differently.
Here is a quick code snippet to help you out.
Here is the XAML:
- First, You need to specify x:Key for each Storyboard
- Storyboards must be found using TryFindResource:
Storyboard myStoryboard = (Storyboard)TryFindResource("myStoryboard"); - TryFindResource will only work if the Storyboard is in the Window.Resources section of the XAML and you're in the code-behind of that XAML
- Once you have the reference to the Storyboard contained in a variable you can call the various Storyboard methods on it. To run it, use the Begin method:
myStoryboard.Begin();
