Better event for item moved events

[Dario Concilio]

Hi to all,

I don't understand witch event is better to intercept when a Shape was moved.

I need to trace when Shape change position.

HI Dario,

It depends on what you are trying to do. If you need to know if the shape changed because the shape needs to update something within itself then use the OnPostiionChanged event of the RadDiagramShapeBase. 

If you need your logic to roll up to the diagram level, use the ItemChanging or ItemChanged event of RadDiagram. This gives you the ability to capture all changes on the diagram.

Hi Dario,

In addition, you can consider the RadDiagram's Drag event. It will fire when you move the shapes with mouse. The given DragRoutedEventArgs will provide start mouse point, end mouse point and the list of dragged items.
