columnToEdit As String)

' Validate the input with a function.
If ValidateCompanyName(rowView(columnToEdit)) Then

Remarks
Use AddNew to add a DataRowView.
The BeginEdit method is identical to the DataRow.BeginEdit method of the DataRow. After calling BeginEdit, any changes made to the DataRowView can be rolled back by calling CancelEdit. Call the BeginEdit method before allowing users to change row values. After values have been changed, you retrieve the new values by setting the RowVersion to DataRowVersion.Proposed. Check the values with a business rule, and roll back the changes if needed by calling CancelEdit, or call EndEdit to accept the changes.
