Edit Controls
The control hosts both a standard text box and a combo box for its edit labels. By default, the text box will be used. If the developer wants a combo box instead, they must first make sure a column for that cell has been created and assigned to the list, and that the EditType property of the column object is set to "ComboBox”. The list items for that combo box can be assigned when the column object is created, or in the BeforeCellEdit event.
The text and combo boxes are fully exposed to the developer. Therefore the developer is able to make changes to those controls as if they created the controls themselves (i.e. Colors, border styles, etc).
