c# - Create Event in WPF -


i want rise event zoom in , zoom out image once gesture recognized valid (gesture recognized kinect). image shown in different user control loaded in frame present in main window. 

<frame name="currentframe" navigationuivisibility="hidden"></frame>

and frame source set this. 

 currentframe.source = new uri("images.xaml", urikind.relativeorabsolute);

how can create custom event? , 1 best ? tunnel or bubble?

i think in case it's better use tunel event, need immediate feedback user interaction , execute single action on that: zooming. there no sence of notifying other controls between usecontrol canvas (if any) , actual handling code.

for concrete implementation of event, can have on:

routed events
