I have a TComboBox and I want to change its dropdown list and replace it with my own control which is (TYazTreeList)
What is the easiest way?
I want to inherit a new control from TComboBox (lets call it TYazComboBox)
Thank you.

TComboBoxsubclasses the Microsoft Windows'COMOBOXwindow class from the Windows Common Control library.COMBOBOXprovides the dropdown, so you should either replace that, or completely write yourTYazComboBoxclass (which some 3rd party Delphi control vendors did). Both options are hard.
