Use with Prism
The RadTransitionControl can be used together with Prism for defining regions. As it derives directly from ContentControl, it can be used as a replacement for it.
Read some more about the Prism library in its github repository.
Example 1: Setting the RegionName attached property
<Grid xmlns:prism="http://prismlibrary.com/"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
<telerik:RadTransitionControl prism:RegionManager.RegionName="ContentRegion">
<telerik:RadTransitionControl.Transition>
<telerikTransitions:MotionBlurredZoomTransition />
</telerik:RadTransitionControl.Transition>
</telerik:RadTransitionControl>
</Grid>
