Swipe gestures in Windows Phone 8.1

Question

In my app i want to be able to recognise certain gestures that occur on an ui element.

So far i have got this: (where main grid is the element)

mainGrid.ManipulationMode = ManipulationModes.TranslateX | ManipulationModes.TranslateY;
mainGrid.ManipulationCompleted += OnManipulationCompleted;

public void OnManipulationCompleted(object sender, ManipulationCompletedEventArgs e)
{
    var velocities = e.Velocities;
}

but i get certain weird errors

Error 1 No overload for 'OnManipulationCompleted' matches delegate 'Windows.UI.Xaml.Input.ManipulationCompletedEventHandler' C:\Visual Studio 2013\Projects\Swell\Swell\MainPage.xaml.cs

OnManipulationCompleted is probably a method provided by your base class its signature does not match.

I suspect that you need to change the name to avoid a conflict such as:

mainGrid.ManipulationCompleted += MainGridManipulationCompleted;

public void MainGridManipulationCompleted(object sender, ManipulationCompletedEventArgs e)
{
    var velocities = e.Velocities;
}

thanks for your reply, but unfortunatly it didnt work – rsharma Nov 18 '14 at 13:52
We may need to see more code then since we don't have the context of surrounding code. ex. what class is your ...Completed event a member of? – jschroedl Nov 18 '14 at 16:44

So i think i fixed it guys

had to change 'ManipulationCompletedEventArgs' to 'ManipulationCompletedRoutedEventArgse'

mainGrid.ManipulationMode = ManipulationModes.TranslateX | ManipulationModes.TranslateY;
mainGrid.ManipulationCompleted += OnManipulationCompleted;

public void OnManipulationCompleted(object sender, ManipulationCompletedRoutedEventArgse)
{
    var velocities = e.Velocities;
}

EDIT: didnt fully fix it,app crashes when getting velocities
