The method is used to set custom error descriptions on specified columns. You can use the ErrorProvider control to display the text of the error.

To examine error descriptions, use the GetColumnError method.

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

If null or an empty string is passed in as the error parameter, the DataRow behaves as if no error was set and the HasErrors property will return false.

To set a custom error description on the whole row, use the RowError property.

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

To set error text that applies to a whole row, set the RowError property.

The following example sets an error description for a specified DataRow.
