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.
