Want a key column combo box field (aka look up the display value based on member value) but when dropped down it expands into a hierarchial grid with the a selectable tree control (aka the tree node is selected that matches the key value). If user clicks a different node of the tree, the internal value matches the new tree node's internal value.
Can u point me to a sample or tell me how to do this?

Is there a sample to do this and be able to select a leaf (it looks similar to what I want except it said that the leaf was not selectable) - then again it is 6 years ago so probably implemented now.
