Gets or sets a value that marks the routed event as handled. Setting to true prevents most handlers along the event route from handling the same event again.
Assembly: System.Windows (in System.Windows.dll)
A property named Handled exists on certain routed event data classes in Silverlight, and setting the value to true influences behavior of the Silverlight event system. If you set to true, then the event will generally not be routed to the next object along the event route. Generally, you set to true as part of an application event handler. You do so because the user action that initiated the event is deemed to be appropriately handled by the other code defined in that event handler. You can still choose to respond to the event in the handler without setting to true, but be aware that other objects in the event route will then receive the event and invoke their own event handlers after the current event handler is exited.
For exceptional cases, you can register handlers for a routed event that can act even if Handled is set to true in the event data. This should be done with caution, because the Handled concept is intended as a system to prevent spurious or repetitive handling of the same event in a complex object tree, and acting on an already-handled event goes against this design.
