Methods

	Name	Description
	Add(ICollection)	Adds the DiagramItem of an ICollection to the end of the DiagramItemCollection
	Add(DiagramItem)	Adds a specific DiagramItem to the collection.
	Clear	Removes all objects from the CollectionBase instance. This method cannot be overridden. (Inherited from CollectionBase.)
	Contains	Determines whether a DiagramItem is in the collection.
	CopyTo	Copies the DiagramItems of the selection to an Array, starting at a particular Array index.
	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.)

	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IndexOf	Returns the zero-based index of the DiagramItem in the collection.
	Insert	Inserts the DiagramItem into the collection at the specified index.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnClear	Performs additional custom processes when clearing the contents of the CollectionBase instance. (Inherited from CollectionBase.)
	OnClearComplete	Performs additional custom processes after clearing the contents of the CollectionBase instance. (Inherited from CollectionBase.)

	OnValidate	Performs additional custom processes when validating a value. (Inherited from CollectionBase.)
	Remove(ICollection)	Removes the specified DiagramItems from an ICollection
	Remove(DiagramItem)	Removes the first occurrence of a specific DiagramItem from the collection.
