Attributes: ProtocolAttribute ProtocolMemberAttribute

Implements: INativeObject IDisposable

Properties

Name	Description
AllowsMoveOperation	Gets a Boolean value that tells whether the session can move items within a single app.
Handle	Handle (pointer) to the unmanaged object representation. (Inherited from INativeObject)
Items	Gets the drag items that are in the session.
RestrictedToDraggingApplication	Gets a Boolean value that tells whether the drag activity is confined to the originating app.

Methods

Name	Description
CanLoadObjects(Class)	Returns a Boolean value that tells whether the session can load objects of the specified class.
HasConformingItems(String[])	TReturns a Boolean value that tells whether the session contains at least one item that is described by any of the specified type identifiers.
LocationInView(UIView)	Returns the location of the drag-drop activity in the coordinate frame of the specified `view`.

Extension Methods

Name	Description
GetHandle(INativeObject)
GetNonNullHandle(INativeObject, String)
CanLoadObjects(IUIDragDropSession, Type)	Returns `true` if the specified `session` can instantiate items of the specified `type`.
