ToolStrip.OnVisibleChanged Method

Raises the VisibleChanged event.

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

protected override void OnVisibleChanged(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data.

Changing the Enabled property of a ToolStrip does not raise the various *Changed events of a ToolStripItem. Raise those events with specific property settings.

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

The OnVisibleChanged 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 OnVisibleChanged in a derived class, be sure to call the base class’s OnVisibleChanged method so that registered delegates receive the event.
