There is a drop-down list (combo box, style 2) in a column of a grid. The first time the list is dropped down, the width of the list is sometimes narrower than the grid column and sometimes wider than the grid column. If I roll up the list and drop it down again, then on the 2nd and all subsequent drop downs it's the same width as the grid column. This is what I want it to be all the time, but I can't seem to find a way to control its width the first time it's dropped down. I've tried setting the combo box's Width and ColumnWidths properties in various events (GotFocus, DropDown, etc.) but to no avail. Any ideas?
