AutoIncrement in GridTableStyle.GridColumnStyles

I am trying to have an AUTOINCREMENT column withing a datagrid. But i am using a GridTableStyle and GridColumnStyles as i have to have columns with checkboxes and comboboxes. Now autoincrement is available only for DataColumn and GridTableStyle won't let me include a datacolumn as a column. How do i have the firstcolumn as datacolumn and the rest of the datagrid as gridtablestyle.gridcolumnstyles.
