Winforms..

Answer 1

Assuming WinForms, this is the default behavior when the ComboBox has focus.

If you’re not clicking on the ComboBox, you’re going to have to do something about it:

• Listen for the MouseEnter event and set focus on the ComboBox.
• Or, use Key Preview, listen for the q, Up, and Down keys, check the mouse position, and act accordingly.
