Tree control with ComboBox

Question

Hi All,
I have a need for a tree control which supports having a
combobox. I've done extensive research on Google, but came up
empty. If anyone has or can point me to any examples, it would be
greatly appreciated.
Thanks in advance!

Answer 1

Here's a follow-up to my first question.
I found an example of a tree with checkboxes and set out to
modify it so that it would fit my needs. I'm really stumped here,
because it will render a checkbox or radio button fine, but I can't
get it to render a combobox or button. I'd also like the combobox
and button to be on the right side of the parent/child label, is
that possible?
Any help anyone can provide is greatly appreciated.
