Icons in a DataGridViewComboBoxColumn

I have a DataGridViewComboBoxColumn in my application that is defined as follows

DataGridViewComboBoxColumn TransferActionCol = new DataGridViewComboBoxColumn();
TransferActionCol.DataSource = Enum.GetValues(typeof(TransferActionEnum));
TransferActionCol.DataPropertyName = "TransferAction";
TransferActionCol.Name = "Transfer Action";
TransferActionCol.AutoSizeMode = DataGridViewAutoSizeColumnMode.Al开发者_StackOverflow社区lCells;
fileListdataGridView.Columns.Add(TransferActionCol);

TransferActionEnum is an enumeration with values Download, Upload, and Ignore. Everything works fine, but I'd like to know if there is a way to display an icon in the cells of this column rather then the enum text value? If possible I'd like to display the icons both when the user is making a selection, and after.

Would this MSDN Answer work? I'll leave the translation to you:

EDIT: C# version is available at the source page.
