Properties

	Name	Description
	AllowedEffect	Gets which drag-and-drop operations are allowed by the originator (or source) of the drag event.
	Alt	Gets a value indicating whether the Alt key is depressed.
	Control	Gets a value indicating whether the Control key is depressed.
	Data	Gets the IDataObject that contains the data associated with this event.
	DiagramClientView	Gets the DiagramClientView that the DiagramEventArgs originated from. (Inherited from DiagramEventArgs.)
	DiagramHitTestInfo	Gets the hit-test information corresponding to the mouse position. (Inherited from DiagramPointEventArgs.)
	Effect	Gets or sets the target drop effect in a drag-and-drop operation.
	Handled	Gets or sets a value indicating whether this event has been handled. (Inherited from DiagramEventArgs.)
	HitDiagramItem	Gets the diagram item corresponding to the mouse position. (Inherited from DiagramPointEventArgs.)
	IsDropLocationUserSpecified	Gets a value indicating whether the drop location was specified by the user, or if it was manufactured.
	KeyState	Gets the current state of the SHIFT, CTRL, and ALT keys, as well as the state of the mouse buttons. bit 1: the left mouse button bit 2: the right mouse button bit 4: the SHIFT key bit 8: the CONTROL key bit 16: the middle mouse button bit 32: the ALT key
	MousePosition	Gets the mouse position in world units relative to the Diagram's top-left corner. (Inherited from DiagramPointEventArgs.)
	Prototype	Gets the element group prototype associated with this drag operation. This exists within the raw data object, but is provided as a separate property so that individual clients do not have to deserialize this themselves.
	Shift	Gets a value indicating whether the Shift key is depressed.

Methods

	Name	Description
	ComputeEffect	This method returns the single resultant drop effect given the possible effects that the drag/drop target can support. The drag source's allowed effects combined with the key states will be used to determine the resultant effect.
	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.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
