Animate many Usercontrols as endless list

i get a variable number of user controls ordered as a list. My goal is to scroll these controls upwards. When the topmost control left the visi开发者_Python百科ble area i want to remove it from the top and append to the end.

First i tried to animate every control via ThicknessAnimation, but i think this is inefficient as there could be 50+ controls.

As a visual help so see what i include a picture of what i try to achieve.

Any ideas how to get this done?

Thanks in advance.
