Raises the Shown event.

protected:
 virtual void OnShown(EventArgs ^ e);

protected virtual void OnShown(EventArgs e);

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

Protected Overridable Sub OnShown (e As EventArgs)

Parameters

e: EventArgs

A EventArgs that contains the event data.

Remarks

The Shown event occurs whenever the form is first shown.

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

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