After reviewing your sample, I noticed that the code for the ActivatingControl/DeactivatingControl was not included. Are you able to send me your updated sample? In theory and practice, you should be able to extract the source of the ComboBox from the ActivatingControl (because you have access to the actual instance) and replace the source with a modified collection.
I do have 1 question for you. When you say that you want the value of one ComboBox to affect the ComboBox in another cell, are you talking about:
- another cell in a different column, same row?
- another cell in the same column, different row?
