GridView Combobox

[OverCoded]

I have a RadGrid that is being used to display settings for a user control. One of the settings is a font listing for each label on the control. I need this column to be a combobox-column. The problem I am having is that when I use the recommended approach to populating the data for this column I get a choice of only those fonts that have be set and listed in the database. What I need is a combobox in the datagrid with a listing of the system fonts as the ItemSource and the DisplayMemberPath, and SelectedValueMemberPath pointing to the data source. However, this does not seems to work. I think that the only way to do this is to provide some sort of datatable with a column having the same name as the targeted "Font Column" in the data source. Any ideas?

Okay, never mind. after a day and a half I figured it out. I created a dataset class to hold the font listing. It has a single column with the same name as the one in the database. In may case it is called "FONT_NAMES." When I populated the data table I padded the font name with the number of characters allowed in the database to force a match with listing in the database. see below:
*Note this is in a WPF App*

//(1)
private FontListDataTable sysFonts; //Global variable custom dataTable class.


sysFonts = new FontListDataTable(); //Itialized in the constructor.

//(2)Poplate the combobox
    ((GridViewComboBoxColumn)radgrid.Columns["fontColumn"]).ItemsSource = FontList();((GridViewComboBoxColumn)radgrid.Columns["fontColumn"]).DisplayMemberPath = "FONT_NAME";
((GridViewComboBoxColumn)radgrid.Columns["fontColumn"]).SelectedValueMemberPath = "FONT_NAME";
// (3)Poplate the Datatable with font names from the system
private IEnumerable<DataRow> FontList()
        {
            foreach (FontFamily font in Fonts.SystemFontFamilies)
            {
                sysFonts.AddFontNameRow(font.ToString().PadRight(18));
            }
            return sysFonts.AsEnumerable();
        }
// The Custom datatable Class
class FontListDataTable : DataTable
    {

        private global::System.Data.DataColumn columnFONT_NAME;

        public FontListDataTable()
        {
            this.InitVars();
            this.InitClass();
        }

        public global::System.Data.DataColumn FONT_NAMEColumn
        {
            get
            {
                return this.columnFONT_NAME;
            }
        }

        public FontNameRow AddFontNameRow(string FONT_NAME)
        {
            FontNameRow rowFontListDataTableRow = ((FontNameRow)(this.NewRow()));
            object[] columnValuesArray = new object[]{
                FONT_NAME
            };
            rowFontListDataTableRow.ItemArray = columnValuesArray;
            this.Rows.Add(rowFontListDataTableRow);
            return rowFontListDataTableRow;
        }

        internal void InitVars()
        {
            //**!THIS COLUMN MUST MATCH THE DATABASE COLUMN!!
            this.columnFONT_NAME = base.Columns["FONT_NAME"];
        }

        private void InitClass()
        {
            this.columnFONT_NAME = new global::System.Data.DataColumn("FONT_NAME", typeof(string), null, global::System.Data.MappingType.Element);
            base.Columns.Add(this.columnFONT_NAME);
        }

        protected override DataTable CreateInstance()
        {
            return new FontListDataTable();
        }

            }
