By default RadComboBox
is not designed to display data in hierarchical manner. Thus placing RadTreeView
inside editable RadComboBox
might cause the desired by you filtering behavior and functionality not to work as expected - the control does not have implemented logic for filtering hierarchical data.
However, what we could suggest you is to use RadAutoCompleteBox
instead. With some modifications like custom FilteringBehavior
and custom highlight of the matching items the desired behavior and functionality could be achieved. We have created a sample project that demonstrates that - please, check it.
Hopes this helps.
