windows phone - Why TouchDown, TouchUp events don't appear in WPF? -

i'm developping windows phone 7.1 application. create design look blend 4 , then, programme code in wpf.

i have path objects , want observe touchdown , touchup events of objects, problem events don't appear! :o

i have tap , hold events, not touchdown , touchup (in general, events utilize toucheventargs class).

do need external library? can see in msdn, toucheventargs class exists version 4.0 (http://msdn.microsoft.com/en-us/library/system.windows.input.toucheventargs(v=vs.100).aspx).

can help me?

when you're developing windows phone 7.1 app, you're doing silverlight windows phone. not wpf.

the uielement class in silverlight not have touchdown or touchup events, uielement in wpf has.

you may utilize manipulation events instead.
