The DataMap property allows you to implement "translated" rows or columns. In translated rows or columns, the grid does not display the values stored in the cells. Instead, it looks up those values in the column's DataMap and displays the mapped value.

The grid also uses the DataMap value to populate drop-down lists when the column is editable.

Note that the DataMap property has no effect when the RowCol.ComboList property is also set. Using both properties on a single row or column is legal, but it effectively disables the DataMap.
