Integrate a keystroke in datagridviewcombobox that is editable.

Hi Experts

I have a datagridview which has as its first column a datagridviewcombobox. This has been modifed to be editable.

I want to add an autocomplete subroutine that fires off keystrokes in the datagridviewcombobox.

Essentially I want to manage this via a keystoke event..

My issue is: Having pressed a key while in a combobox in the datagridview - how do I capture that keystroke? How do I test to see which combobox it is?

I thought using keyup for the datagridview but how do I know which combobox to work on.

Below is code similar to what I will use for autocomplete - but how to apply that to a combobox in a datagridview??
