ListBoxItem.OnMouseLeftButtonDown Method

Provides handling for the MouseLeftButtonDown event.

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

protected override void OnMouseLeftButtonDown(
	MouseButtonEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseButtonEventArgs
The event data.

This implementation marks the event as handled by setting the Handled property of the event data to true.

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