c# - Multi-touch buttons on Windows Phone 8 -

-

i using bunch of rectangle shapes in windows phone 8 app , need support multi-touch few of them can tapped @ 1 time. not doing handling on thought multi-touch supported default in windows phone 8 apps.

everything written in c# , xaml. when try press 2 rectangles @ same time tap event never gets hit on either of them.

thank thoughts on this.

xaml of tiles:

<rectangle x:name="tile11" horizontalalignment="left" height="103" margin="10,22,0,0" verticalalignment="top" width="103" tap="tileclickhandler" hold="tileholdhandler" mouseleftbuttondown="tile11_mouseleftbuttondown" mouseleftbuttonup="tile11_mouseleftbuttonup">                 <rectangle.fill>                     <imagebrush stretch="fill" imagesource="/assets/tiles/default.png"/>                 </rectangle.fill>             </rectangle>             <rectangle x:name="tile12" horizontalalignment="left" height="103" margin="120,22,0,0" verticalalignment="top" width="103" tap="tileclickhandler" hold="tileholdhandler" mouseleftbuttondown="tile11_mouseleftbuttondown" mouseleftbuttonup="tile11_mouseleftbuttonup">                 <rectangle.fill>                     <imagebrush stretch="fill" imagesource="/assets/tiles/default.png"/>                 </rectangle.fill>             </rectangle>             <rectangle x:name="tile14" horizontalalignment="left" height="103" margin="340,22,0,0" verticalalignment="top" width="103" tap="tileclickhandler" hold="tileholdhandler" mouseleftbuttondown="tile11_mouseleftbuttondown" mouseleftbuttonup="tile11_mouseleftbuttonup">                 <rectangle.fill>                     <imagebrush stretch="fill" imagesource="/assets/tiles/default.png"/>                 </rectangle.fill>             </rectangle>

one tap handler three:

private void tileclickhandler(object sender, system.windows.input.gestureeventargs e)         {             if (isrecordingactive)             {                 stoprecording();                 isrecordingactive = false;                 managetilestate(activerecordingtile, constants.tilestates.has_sound);             }             else             {                 system.windows.shapes.rectangle tile = (system.windows.shapes.rectangle)sender;                 if (doestilehavesound(tile))                 {                     thread soundthread = new thread(new parameterizedthreadstart(playsound));                     soundthread.start(tile.name);                 }             }         }

i had come own multitouch logic. meaning using touch detection - , keep track of has been touched in each frame. when element gets touch free decide action take.
