ListBoxItem.OnMouseLeftButtonDown Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Provides handling for the MouseLeftButtonDown event.
Namespace: System.Windows.Controls
Assembly: System.Windows (in System.Windows.dll)
Syntax
'Declaration
Protected Overrides Sub OnMouseLeftButtonDown ( _
e As MouseButtonEventArgs _
)
protected override void OnMouseLeftButtonDown(
MouseButtonEventArgs e
)
Parameters
- e
Type: System.Windows.Input.MouseButtonEventArgs
The event data.
Remarks
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.
