Animation problem

PaulHuppé — Thu, 27 Oct 2011 11:38:32 GMT

Hi,

I am trying to add animations to some panels and running into a problem. I have a first panel which contains some navigation tools like ZoomIn, ZoomOut, ZoomToLocation, Pa, etc. I have a second panel which will contain the ZoomToLocation controls. My problem is that the animation to open/close the second panel does not work properly. If I have the second panel open on startup, then the close button I have in that panel works fine and the panel closes using the animation. But, the button in the first panel which is should open the second panel using an animation does not do anything. I have been looking at the code so much that maybe I am not seeing something obvious. Here is the code. I have removed most of the buttons and extra stuff to keep it short:

That's a lot of code and is kind of difficult to read. This also seems like the kind of question that is best answered at a Silverlight forum http://forums.silverlight.net/. And you might also want to try to use ExpressionBlend to set up your animation. This might be the simplest solution.

Ok, I will try on that forum.
Thanks,
