Implementing DragStarted DragDelta events in windows 8 / WinRT -

how can attach dragstarted dragdelta events grid in windows 8 / winrt. did same in windows phone gestureservice.getgesturelistener() method. tried replace code manipulationstarted & manipulationdelta events in windows 8. result not same. in windows phone single drag enters dragdelta events 2 or more times. in other hand in windows 8, in manupulationdelta event fires once similar drag operation.

yeah, think know want.

let's have xaml this:

<grid margin="50">     <grid.columndefinitions>         <columndefinition />         <columndefinition />     </grid.columndefinitions>     <grid.rowdefinitions>         <rowdefinition />         <rowdefinition />     </grid.rowdefinitions>     <rectangle fill="blue" x:name="myrect" /> </grid> 

you want move rectangle around grid dragging it.

just use code:

public mainpage() {     this.initializecomponent();     myrect.manipulationmode = manipulationmodes.translatex | manipulationmodes.translatey;     myrect.manipulationdelta += rectangle_manipulationdelta;     myrect.manipulationcompleted += rectangle_manipulationcompleted; }  private void rectangle_manipulationdelta(object sender, manipulationdeltaroutedeventargs e) {     var _rectangle = sender windows.ui.xaml.shapes.rectangle;     var _transform = (_rectangle.rendertransform = (_rectangle.rendertransform translatetransform) ?? new translatetransform()) translatetransform;     _transform.x += e.delta.translation.x;     _transform.y += e.delta.translation.y; }  private void rectangle_manipulationcompleted(object sender, manipulationcompletedroutedeventargs e) {     var _rectangle = sender windows.ui.xaml.shapes.rectangle;     _rectangle.rendertransform = null;      var _column = system.convert.toint16(_rectangle.getvalue(grid.columnproperty));     if (_column <= 0 && e.cumulative.translation.x > _rectangle.rendersize.width * .5)         _rectangle.setvalue(grid.columnproperty, 1);     else if (_column == 1 && e.cumulative.translation.x < _rectangle.rendersize.width * -.5)         _rectangle.setvalue(grid.columnproperty, 0);      var _row = system.convert.toint16(_rectangle.getvalue(grid.rowproperty));     if (_row <= 0 && e.cumulative.translation.y > _rectangle.rendersize.height * .5)         _rectangle.setvalue(grid.rowproperty, 1);     else if (_row == 1 && e.cumulative.translation.y < _rectangle.rendersize.height * -.5)         _rectangle.setvalue(grid.rowproperty, 0); } 

for this:

hope i'm close! best of luck!
