i have following code found here:
private void grid_manipulationstarted_1(object sender, manipulationstartedroutedeventargs e) { initialpoint = e.position; } private void grid_manipulationdelta_1(object sender, manipulationdeltaroutedeventargs e) { if (e.isinertial) { point currentpoint = e.position; if (currentpoint.x - initialpoint.x >= 500)//500 threshold value, want trigger swipe right event { system.diagnostics.debug.writeline("swipe right"); e.complete(); } } } and xaml:

also, grid inside viewbox, in page (not window).
any appreciated :).
i guess meant windows phone 8.1 runtime application? because in silverlight works fine. should set manipulationmode all grid. in test worked fine without background color (which necessary in silverlight applications).
if need subset of manipulations, should use best mode needs.
