Hi Prokopis,
You can''t do this with the normal combobox cell. The dropdown part of the combobox is the windowsform''s ListBox. Instead of a ComboBox celltype, you can use a GridListControl celltype and display an icon in a column.
Here is a sample. This will work if you have an ArrayList/ DataTable as the datasource. You can create an DataTable object and load the items to it.
This is achieved by subscribing to the dropdown''s embedded grid''s PrepareViewStyleInfo event and dynamically setting e.Style.ImageIndex and e.Style.ImageList.
Best regards,
Jay
