Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The DataGridView control changes the Cursor property value depending on the location of the mouse pointer. The UserSetCursor property stores the normal value of the Cursor property and ignores the control's changes. This method is called when the CursorChanged event occurs, and it updates the UserSetCursor property, if necessary, in addition to invoking any event handlers.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.Notes to Inheritors
When overriding in a derived class, be sure to call the base class’s method so that registered delegates receive the event.
