[…] I came across a really great solution on Rob’s Usability Development blog for creating an AnimationHelperControl to give you something to animate. His post also made use of his excellent AnimateTo extension […]

Thanks Robertjan,
It feels like the same idea should be possible to apply with WPF as it’s basically the same thing as Silverlight….but I might be wrong… I look forward to your demo project.

I really appreciate your help,
Anders

Hi Anders,

I’m not sure what is causing the error in your application, not that familiar with WPF. I’ll try to upload a Demo Project kater today so you can compare it yourself.

Cheers,
Robertjan

Very smart idea Roberjan!

I’m trying to use the same solution in WPF instead of Silverlight but fail. It’s something wrong with the mysterious property path string. I get an InvalidOperationException from the Storyboard.Begin() call within AnimateToDouble(…) with the exception message:
“Cannot resolve all property references in the property path ‘(StoryboardAnimationHelper.DoubleValue)’. Verify that applicable objects support the properties.”

I cannot say I’m understanding how the property path string is constructed and I’ve tried a number of alternatives that I thought would be correct but with the same result. E.g., my best guess was that the property path string should have been “(AnimationHelperControl.DoubleValue)”…but no…

Perhaps I’m missing something fundamental. Did you upload you Demo project somewhere that I might get some clues from?

Thanks,
Anders
