After calling CancelEdit, all changes to the row are rolled back. You can also roll back changes by calling RejectChanges on the parent DataTable.

The following example edits a row in a DataView. The CancelEdit method is called to cancel the changes if the validation fails.

Private Sub EditDataRowView(rowView As DataRowView, _
    columnToEdit As String)
    rowView.BeginEdit()
    rowView(columnToEdit) = textBox1.Text

    ' Validate the input with a function.
    If ValidateCompanyName(rowView(columnToEdit)) Then
        rowView.EndEdit()
    Else
        rowView.CancelEdit()
    End If
End Sub

Private Function ValidateCompanyName( _
    valuetoCheck As Object) As Boolean
    ' Insert code to validate the value.
    Return True
End Function
