I would like to use a radtreeview as a Question and Answer List the parent is the question and the child nodes are the answers to the question. I need only one child node checkable under each parent node Anyone have an idea of how to make this happen. Attached is a screenshot of the treeview.
Attach the "OnClientNodeChecking" event to
RadTreeView and check for whether a node is already checked in same
level. If yes, either you can cancel the event or uncheck the already
checked one using client code. The following documentation will help you
to achieve the functionality.
