I have used two slider control and used ManipulationDelta event to handle multitouch events. and depending on the movement of the slider some process happen. Now the issue is in my canvas movement of the object get freeze when i move my slider through touch screen.

I read somewhere, optimizing the outside code will work. but in my case i am not able to change my code outside the event.

Here is my code,
private void slider_ManipulationDelta(object sender, ManipulationDelataEventArgs e)
 slider.value += e.DeltaManipulation.Translation.X;
 Canvas.SetLeft(rectangle, slider.value *2);

Edit :
1) I have removed all code from event but still it is freeze when dealing with multiple slider control
2) I have DispatcherTimer to update other UI element on Canvas on slider.Value

Try to create New Process then add your code in that Event
it should work

Sometimes the Event will not work correctly in debugging mode\
try to create EXE and check it without debugging

i have release the exe and execute it. but no hope :(

i am not familiar with this ManipulationDelta but i think it's a 3rd Party Solution.
so make sure you have the last release, and check with them.

No it's Dot net framework event in WPF.
