WPF UserControl Transition

I have a Main Window which has a Grid. On Button Click Events, I switch the children of the Grid between multiple UserControls. When I switch between these user controls I want to create a transition, something like fade or slide in etc. How can I 开发者_开发问答do this?

You can do this using Expression Blend, and either creating your own, or using pre-made visual transitions.

FluidMoveBehaviour is a common one for animating the removal and addition of objects to a content control. There are also some 'pseudo-3d' animations such as flip, rotate etc...
