Tag Visualizer Events



The Tag Visualizer Events sample application shows how to implement hit-testing functionality to allow UI elements to react when tagged objects move over them.

Tag Visualizer Events sample application

API Concepts Exposed

This sample shows how to:

  • Use the TagVisualizer control to recognize tagged objects.

  • Make UI elements react when tagged objects move over them. This behavior works regardless of whether the tagged object moves over the UI element, or the UI element moves under the tagged object.

  • Make TagVisualization controls react when they move over other UI elements.

  • Encapsulate the above functionality in a reusable, XAML-friendly class that's portable between applications.

You can place any tagged object on the application, which will display a light blue elliptical visualization around the tag. When the tagged object moves over one of the UI elements in the application, the UI element becomes light blue instead.
