OnMouseLeaveElement Method (UltraTabbedMdiManager)

Raises the Infragistics.Win.UltraComponentControlManagerBase.MouseLeaveElement event when the mouse is moved out of a UIElement.

Syntax

Visual Basic

'Declaration
 
Protected Overrides Sub OnMouseLeaveElement( _
   ByVal e As Infragistics.Win.UIElementEventArgs _
) 

C#

protected override void OnMouseLeaveElement( 
   Infragistics.Win.UIElementEventArgs e
)

Parameters

e

A Infragistics.Win.UIElementEventArgs that provides data for the event.

Remarks

Raising an event invokes the event handler through a delegate.

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

Example

In addition to the standard mouse events (i.e. MouseDown, MouseMove, MouseUp, MouseEnter, MouseLeave etc.) all PLF based controls expose 2 new events called MouseEnterElement and MouseLeaveElement.

The following code writes the type of each element as it is entered and exited to the output window.
