ToolStripDropDown.OnClosing Method (ToolStripDropDownClosingEventArgs)

 

Raises the Closing event.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected virtual void OnClosing(
	ToolStripDropDownClosingEventArgs e
)

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnClosing 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 OnClosing in a derived class, be sure to call the base class's OnClosing method so that registered delegates receive the event.
