Microsoft Silverlight will reach end of support after October 2021. Learn more.

Provides handling for the MouseLeave event that occurs when the mouse pointer leaves the combo box.

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

Syntax

'Declaration
Protected Overrides Sub OnMouseLeave ( _
    e As MouseEventArgs _
)

protected override void OnMouseLeave(
    MouseEventArgs e
)

Parameters

Remarks

This implementation updates the visual state of the ComboBox when the mouse pointer is over the control.

The OnMouseLeave method is called before any event handler for the MouseLeave event is called. This method allows derived classes to handle the MouseEnter 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, make sure to call the base class’s OnMouseLeave method so that registered delegates receive the event.
