DateTimePicker.OnValueChanged(EventArgs) DateTimePicker.OnValueChanged(EventArgs) DateTimePicker.OnValueChanged(EventArgs) Method

Definition

Raises the ValueChanged event.

protected:
 virtual void OnValueChanged(EventArgs ^ eventargs);
protected virtual void OnValueChanged (EventArgs eventargs);
abstract member OnValueChanged : EventArgs -> unit
override this.OnValueChanged : EventArgs -> unit

Parameters

eventargs
EventArgs EventArgs EventArgs

An EventArgs that contains the event data.

Remarks

The ValueChanged event occurs when the value for the control changes.

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

The OnValueChanged 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 OnValueChanged(EventArgs) in a derived class, be sure to call the base class' OnValueChanged(EventArgs) method so that registered delegates receive the event.
