Assembly: PresentationCore (in presentationcore.dll)
One of the enumeration values.
Return ValueA boolean that indicates whether UI Automation is listening for the event.
Typically, you call this method before creating the AutomationPeer that raises the event. This method is a performance measure because if UI Automation does not listen for the event, it does not make sense to create a peer to raise one.
This method is static and only answers if a delegate listens for the specified event in UI Automation, not for an event on a specific element. UI Automation can create broadcast listeners; therefore the per-element information is irrelevant.
