Error in a DataGrid

Hello:

I have an event in datagrid (method-id dgridRubricas_MouseDoubleClick) that works perfectly when I click with the mouse in a cell.

It turns out that when I click the mouse on the scroll bar to move down to the remaining data visualization, and make very fast, is considered a MouseDoubleClick and gives the following error "Null Reference Exception was unhandled".

What is the solucção to prevent this situation?

Best Regards

    Hallo

    Here my solution in a WPF program:

          method-id KontoGrid_MouseDoubleClick.

          procedure division using by value sender as type Object

                                   by value e as type System.Windows.Input.MouseButtonEventArgs.

              set KomtoItem to KontoGrid::Items::CurrentItem as type xyz

              if KontoItem = null

                 goback

              end-if

              *> do processing

              goback.

          end method.
