I have a column (EFS-Web Category) that's defined as type combo (MyiGrid.ColDefaultCell(n).eType = igCellCombo). The documentation says the button by default is visible. But I find you have to click into the cell for it to appear.

Do you have a response for this?
To specify whether combo buttons visible in all cells regardless of their 'current cell' status, use the ShowControlsInAllCells property. The default value of this property is False - change it to True to solve your problem.
