'Declaration Public Property SelectedDataItems As Object()
public object[] SelectedDataItems {get; set;}
This property is exposed as an object array (instead of IEnumerable or IList) so that there should be no confusion about its behavior. When the selection changes a new object array is created (as an atomic operation) from the SelectedItems collection. The DiagramItem.Content of each DiagramItem in that collection is used to popluate the new array. To change the diagram items selection an application can set this property (either explicitly or through a binding) to a new array of its data items.
