HandledEventHandler Delegate

Represents a method that can handle events which may or may not require further processing after the event handler has returned.

Namespace: System.ComponentModel
Assembly: System (in system.dll)

public delegate void HandledEventHandler (
	Object sender,
	HandledEventArgs e
)
/** @delegate */
public delegate void HandledEventHandler (
	Object sender, 
	HandledEventArgs e
)
Not applicable.

Parameters

sender

The source of the event.

e

A HandledEventArgs that contains the event data.

This delegate is available for use with your own events when the HandledEventArgs.Handled property provides sufficient event data. The event handler can set the Handled property to true if all necessary processing has been completed in the handler.

Typically, events that require this functionality will also require additional event data, and will use a class that derives from HandledEventArgs along with a corresponding, similarly-named delegate type. For example, the DataGridView.RowPrePaint event uses the DataGridViewRowPrePaintEventArgs event-data type and the DataGridViewRowPrePaintEventHandler delegate type. Because delegates are not inherited, the HandledEventHandler is rarely used.
