windows 8 - ScrollViewer and handling manipulation events on child elements

Question

I have created a Windows 8 Store App using C# / XAML. My interface includes a scrollable list, which is rendered using an ScrollViewer. I would like to be able to handle manipulation events on the elements within the list, however, setting ManipulationMode to anything other than None on the list element causes my list to no longer scroll.

Here is a simplified version of the UI:

<ScrollViewer>
  <Border/> <!-- these contain child content -->
  <Border/>
  <Border/>
  <!-- Set ManipulationMode on an element in order to receive manipulation events -->
  <!-- This causes the scroll viewer to stop working! -->
  <Border ManipulationMode="All"
          ManipulationDelta="..."/>
  <Border/>
  <Border/>
</ScrollViewer>

I understand that the WinRT ScrollViewer uses a special ManipulationMode of System for performance reasons, but I would like to have a vertically scrolling list, containing elements that respond to horizontal manipulation / gestures. Can anyone think of a creative workaround that would make this possible?

Answer 1

it may be long time but didn't find any good solution. I just achieved what I wanted very easily.

public MovableGrid()
        {
            ManipulationMode = ManipulationModes.TranslateX | ManipulationModes.System;
            AddHandler(ManipulationDeltaEvent, new ManipulationDeltaEventHandler(UIElement_OnManipulationDelta), true);
            AddHandler(ManipulationCompletedEvent, new ManipulationCompletedEventHandler(UIElement_OnManipulationCompleted), true);
        }

I wanted my MovableGrid to be moved on X axis and I have list of MovableGrids which I wanted to be scrolled with scrollviewer. That's enough to do that.
