animations

I have the following Storyboard:

'LayoutMargin' is a dependency property defined in the ancestor Window. This is the problem I'm having: The first time I run the animation it doesn't work - as if the LayoutMargin.Value isn't set. However, the second time I run the animation, and all subsequent times I run the animation, it work just fine. At first I suspected the LayoutMargin.Value was not set prior to the first animation, but it is set.

Does anyone have any ideas about why this is happening?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
