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

Public Event LostStylusCapture As StylusEventHandler

AddHandler instance.LostStylusCapture, handler
<object LostStylusCapture="StylusEventHandler" .../>

Routing strategy




  • There is no defined corresponding tunneling event.

  • Override OnLostStylusCapture to implement class handling for this event in derived classes.

When an element captures the stylus, it receives stylus input even if the pointer is outside its bounds. The stylus is typically captured only during drag-and-drop operations.

Because this event uses bubbling routing, the element that loses focus might be a child element instead of the element where the event handler is actually attached. Check the Source in the event data to determine the actual element that lost focus.

This event creates an alias for the Stylus.LostStylusCapture attached event for this class, so that LostStylusCapture is part of the class members list when UIElement3D is inherited as a base element. Event handlers that are attached to the LostStylusCapture event are attached to the underlying Stylus.LostStylusCapture attached event and receive the same event data instance.

LostStylusCapture is introduced in the .NET Framework version 3.5. For more information, see .NET Framework 3.5 Architecture.
