Well, this looked to be just what I needed, but I haven't been able to
get it to work.
In the code below I have my original generic list, myColumns, and my
BindingList, bColumns.  I populate bColumns, and I confirm that I can
get a value from the 'DB_Column_Name' property.
Then I try to populate a dropdownlist box.  Perhaps I may be using the
wrong syntax here.
But I also try to populate a datagrid, and get an error saying that
'DB_Column_Name' is not found.  If I try change the grid to
AutoGenerateColumns="True", it still does not work.

        List<MasterColumnRecord> myColumns = wcc.Columns;

        BindingList<MasterColumnRecord> bColumns = new
BindingList<MasterColumnRecord>();
        foreach (MasterColumnRecord mcr in myColumns)
        {
            bColumns.Add(mcr);
        }
        string test = bColumns[0].DB_Column_Name;

        SortList.DataSource = bColumns;
        SortList.DataMember = "DB_Column_Name";
        SortList.DataBind();

        DataGrid1.DataSource = bColumns;
        DataGrid1.DataBind();
