Timer.OnTick Method

Raises the Tick event.

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

protected virtual void OnTick(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data. This is always Empty.

This method is called for each timer tick. It calls any methods that are added through Tick. If you are inheriting from Timer, you can override this method.

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

Notes to Inheritors

When overriding OnTick in a derived class, make sure that you call the base class's OnTick method.
