Well, RadTreeNodeData() could have had a Boolean for Checked State but it does not have any field to set whether its checked or not.

Hi Piyush,
I didn't understand how you loose the checked state of the node when you expand it. In this demo in the first RadTreeView you'll see that when you expand "Software" root node for example and check whatever checkbox you want from it's childnodes - it's state will become so called "Undefined". But when you select the button "More Info On Selected Notes" Software root node will be in the list of checked nodes.
Please attach the full code so we can be able to help you.
All the best,
