Use the DataRow.SetColumnError(int, string) method to set column errors.

To determine whether any errors exist for the columns collection, use the DataRow.HasErrors method. Consequently, you can use the DataRow.GetColumnsInError method to retrieve all the columns with errors.

To clear all errors for the columns collection, use the DataRow.ClearErrors method.
