How can I show animation while -

1. Switching from one Layouting to another (I have a dropdown with layout names, on selection change, I create object of the desired Layouting class, and call Arrange() on the diagram object.

2. When I double click a node, I add new nodes (child node to that node and join them using links), so is animation possible here as well?

Please provide any sample code if you have.

Amit
