I have a DataGridView that contains 3 columns, the first is a drop down and the second and third are textboxes. However, the third one is read-only and is only there to provide information to the user on the item selected from the dropdown column.
If the user changes the drop-down, I need to update the text in the third column appropriately, but my problem is finding the appropriate event to handle this. I need the update to occur immediately, not after the row is validated, or after the row is committed. The information that the user enters in the second box is somewhat dependant on what the third box says.
