Control.CursorChanged Event

Occurs when the value of the Cursor property changes.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public:
event EventHandler^ CursorChanged {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);
}
/** @event */
public void add_CursorChanged (EventHandler value)

/** @event */
public void remove_CursorChanged (EventHandler value)

JScript supports the use of events, but not the declaration of new ones.

This event is raised if the Cursor property is changed by either a programmatic modification or user interaction.

For more information about handling events, see Consuming Events.

The following code example demonstrates changing the mouse cursor using the Control.Cursor property, the Cursor class, and the Cursors class. The example creates a form that contains a ComboBox control, a Panel control, and a ListView control. The ComboBox contains all cursors provided by the Cursors class. When the user selects a mouse cursor in the ComboBox, the Control.Cursor property is set to the selected cursor, which updates the cursor for the Panel. The ListView is updated every time the Control.CursorChanged event occurs.
