object uRow = this.Table.Rows[iRow][cname];
System.TypeCode utype = System.Type.GetTypeCode(GetType());
//this.Table.Rows[iRow][cname].GetType());
if (utype.GetType() == typeof(System.DBNull))
{
//if (this.TreatNullAsType)
//{
return dvNulls.DefaultTypeValue(uRow);
//this.Table.Columns[cname].DataType);

}

return uRow; // this.Table.Rows[iRow][cname];

//supporting static class
