Is there a way to determine if a combobox's choices are active? That is, that the user has clicked the dropdown arrow or has pressed F4. I have a combobox in a grid which has code in the KeyPress Event to trap the up and down arrow. The code SKIPs up or down in the grid respectively instead of combobox's value. This part works great. However, when the user activates the combobox I want the up and down arrow keys to act normally.
