Phone 7 Bing map control - Add a pushpin when tap -

i using latest phone 7 rtm tools ( downloaded today, october 7 2010).

i trying simple thing here:

when user taps once on map control, want put pushpin there. also, want keep regular built-in behavior of map control ( tap twice zoom).

(if it's not possible keep both behaviors , maybe long press on map put pushpin).

when trying figuring out, came across documentation of changes made control map phone7: http://msdn.microsoft.com/en-us/library/ff955762.aspx

then saw new class mapinputeventargs, has viewportpoint member.

when looking @ code examples on regular silverlight map control saw this:

private void onmouseclick(object sender, mapmouseeventargs e)     {         point clicklocation = e.viewportpoint;         location location = x_map.viewportpointtolocation(clicklocation);          pushpin pushpin = new pushpin();          m_pushpinlayer.addchild(pushpin, new location(latitude, longitude));     } 

but in phone7 case, can't find appropriate event handler, , not find uses mapinputeventargs in map control. searching on google gets me 1 result !!

so , appropriate event "tap once", , how can viewportpoint after event has been fired ?

thanks in advance.

just figured out if still having problems.

the mouseleftbuttonup , mouseleftbuttondown events have getposition method return point looking for

 private void mapmain_mouseleftbuttonup(object sender, mousebuttoneventargs e)     {          point p = e.getposition(this.mapmain);         geocoordinate geo = new geocoordinate();         geo = mapmain.viewportpointtolocation(p);         mapmain.zoomlevel = 17;         mapmain.center = geo;         //---create new pushpin---         pushpin pin = new pushpin();          //---set location pushpin---         pin.location = geo;          //---add pushpin map---         mapmain.children.add(pin);     }
