DateTime dtFoxProNull = DateTime.Parse("12/30/1899"); foreach (DataRow dr in ds.Tables["MyTable"].Rows) { if (DateTime.Parse(dr["theColumn"].ToString()) == dtFoxProNull) dr["theColumn"] = DBNull.Value; ] ds.AcceptChanges;>I can display a valid check date in the CheckDate field in my grid, however, if the check date is null, my grid is displaying a generic date of 12/30/1899. Why? Can I see a blank field if there is no check date? Once I assign a valid check date to a particular transaction, it overrides the generic date of 12/30/1899 to display the correct date. I need to see NULL dates!
