Properties

	Name	Description
	AnchorItem	Gets or sets the DiagramItem that serves as the anchor for extending the selection.
	BoundingBox	Gets the bounding rectangle surrounding all selected ShapeElements in world units relative to the diagram's top-left.
	Count	Gets the number of ShapeElements in the selection.
	EditItem	Gets the item to edit. This is typically the FocusedItem.
	FocusedItem	Gets or sets the DiagramItem that has the focus.
	IsDeferredSelectionPending	Gets a value indicating whether a deferred selection is pending.
	IsSynchronized	Gets a value indicating whether access to the collection is synchronized (thread-safe).
	PrimaryItem	Gets the primary DiagramItem in the selection.
	RepresentedElements	Gets corresponding ModelElements that represent this selection.
	SelectionRules	Gets the DiagramSelectionRules object that constrains how ShapeElements can be added and removed from the selection.
	SyncRoot	Gets an object that can be used to synchronize access to the collection.
	TopLevelItems	Gets the top level items in the selection.

Methods

	Name	Description
	Add(DiagramItem)	Adds a DiagramItem to the current selection.
	Add(DiagramItemCollection)	Adds the specified DiagramItems to the current selection.
	CanEditValue	Returns a value indicating whether this DiagramItem can be edited.
	Clear	Clears the current selection.
	CommitPendingEdit	Commits the in-place edit.
	Contains	Gets a value indicating whether the selection contains the specified DiagramItem.
	CopyTo(Array, Int32)	Copies the ShapeElements of the selection to an Array, starting at a particular Array index.
	CopyTo(array<DiagramItem[], Int32)	Copies the DiagramItems of the selection to a DiagramItem[] array, starting at a particular Array index.
	DeferredAdd	Defers adding a DiagramItem to the selection until ElementEventsEnded is raised. The DeferredAdd, DeferredRemove, DeferredPrimaryItem, and DeferredClear methods define the parameters to use in a single call to set the selection when ElementEventsEnded is raised.
	DeferredClearBeforeAdditions	Defers clearing the selection until ElementEventsEnded is raised. This clears the selection first, and then any deferred additions or removals are applied. The DeferredAdd, DeferredRemove, DeferredPrimaryItem, and DeferredClear methods define the parameters to use in a single call to set the selection when ElementEventsEnded is raised.
	DeferredPrimaryItem	Defers setting the primary item in the selection until ElementEventsEnded is raised. The DeferredAdd, DeferredRemove, DeferredPrimaryItem, and DeferredClear methods define the parameters to use in a single call to set the selection when ElementEventsEnded is raised.
	DeferredRemove	Defers removing a DiagramItem from the selection until ElementEventsEnded is raised. The DeferredAdd, DeferredRemove, DeferredPrimaryItem, and DeferredClear methods define the parameters to use in a single call to set the selection when ElementEventsEnded is raised.
	Dispose()	Releases all resources used by the current instance of the SelectedShapesCollection class.
	Dispose(Boolean)
	EditValue	Invoke the in-place editor for this DiagramItem.
	EnsureVisible()	Ensures that the selection is within the view. If it is not, it is centered in the view. If the selection is the diagram, then nothing happens.
	EnsureVisible(DiagramClientView.EnsureVisiblePreferences)	Ensures that the selection is within the view. If the selection is the diagram, then nothing happens.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	FindFirstFocusableDiagramItem	Given the specified diagram item, find the first diagram item that can receive focus. If the specified diagram item can receive focus, a clone of it is returned. If the diagram item is not focusable, then its first focusable descendant is returned, if any. If that search fails, then the parent hierarchy is traversed for the first focusable ancestor.
	FindFirstSelectableDiagramItem	Given the specified diagram item, find the first selectable diagram item. If the specified diagram item is selectable, a clone of it is returned. If the diagram item is not selectable, then the parent hierarchy is traversed for the first selectable ancestor.
	GetDiagramItemsContainingShape	Gets a collection of diagram items in the selection whose Shape property is the specified shape.
	GetEnumerator	Returns an enumerator that can iterate through the DiagramItem collection.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	HasPendingEdit	Returns a value indicating whether in-place editing is active.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSelectionChangedByDeletion	Raises the SelectionChangedByDeletion event.
	OnShapeSelectionChanged
	OnShapeSelectionChanging
	Remove(DiagramItem)	Removes a DiagramItem from the current selection.
	Remove(DiagramItemCollection)	Removes the specified DiagramItems from the current selection.
	SelectFocusedItemOrAncestor	Selects the currently focused item in the selection (which may or may not be selected). If it is not selectable, the parent chain will be searched for the first selectable ancestor. The focused item remains unchanged.
	Set(DiagramItem)	Replaces the current selection with a new single selection.
	Set(DiagramItemCollection)	Replaces the current selection with a new selection.
	SetDeferredSelection	Sets the selection using the information gathered from DeferredAdd, DeferredRemove, DeferredPrimaryItem, and DeferredClear. If no deferred information is available, then this method does nothing. This method is intended to be called only during OnElementEventsEnded.
	Toggle(DiagramItem)	Toggles the specified DiagramItem into or out of the selection; i.e., if the DiagramItem is selected, it is deselected. If the DiagramItem is not selected, it is selected.
	Toggle(DiagramItemCollection)	Toggles the specified DiagramItems into or out of the selection; i.e., if a DiagramItem is selected, it is deselected. If a DiagramItem is not selected, it is selected.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	SelectionChangedByDeletion	Occurs when the selection is about to change because a ModelElement that an item in the selection refers to has been deleted.
	ShapeSelectionChanged	Occurs when the selection has changed.
	ShapeSelectionChanging	Occurs when the selection is about to change.
