Hi Gary C,
The new behavior is a part of the Telerik Presentation Framework optimizations introduced in Q3 2009. Still, if you want your RadLabel to get a valid size before it is added to a parent container, you need to call the LoadElementTree method:
RadLabel rl =
"This is a test"
// at this points the size is (67, 14)
I hope this helps. If you have additional questions, feel free to contact me.
