ToolStripItem.OnMouseLeave Method (EventArgs)


Raises the MouseLeave event.

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

protected virtual void OnMouseLeave(
	EventArgs e


Type: System.EventArgs

An EventArgs that contains the event data.

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

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

The following code example demonstrates how to override the OnMouseLeave method. This code example is part of a larger example provided for the ToolStripItem class.

// This method defines the behavior of the MouseLeave event.
// It sets the state of the rolloverValue field to false and
// tells the control to repaint.
protected override void OnMouseLeave(EventArgs e)

    this.rolloverValue = false;
