ComboBox.OnTextUpdate(EventArgs) Method

Definition

Namespace:: System.Windows.Forms

Assembly:: System.Windows.Forms.dll

Raises the TextUpdate event.

protected:
 virtual void OnTextUpdate(EventArgs ^ e);

protected virtual void OnTextUpdate (EventArgs e);

abstract member OnTextUpdate : EventArgs -> unit
override this.OnTextUpdate : EventArgs -> unit

Protected Overridable Sub OnTextUpdate (e As EventArgs)

Parameters

e: EventArgs

An EventArgs that contains the event data.

Remarks

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

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