Assigning the Storyboard.Target on something gives me a weird error.

Question

When I write Storyboard.Target, intellisense steps in and does it's job. But when I compile it, I get an exception. But if it's no allowed, why does intellisense pull it for me to use?

I want to assign myStoryboard to myRectangle. What am I doing wrong?

Answer 1

Try

Storyboard.TargetProperty="(UIElement.Height)"

Answer 2

You want to set Storyboard.TargetName not Storyboard.Target.
