Application crashing when animation used in gridview and reordering

[moc426]

Hi

I am having trouble with a basic animation to elements on a usercontrol. Here is my animation code:

            visual = ElementCompositionPreview.GetElementVisual(gImage);
            Compositor compositor = visual.Compositor;

            var animation = compositor.CreateVector3KeyFrameAnimation();

            animation.InsertKeyFrame(0f, new Vector3(0f, 0f, 0f));
            animation.InsertKeyFrame(0.50f, new Vector3(0, -50f, 0f));
            animation.InsertKeyFrame(1f, new Vector3(0, 0f, 0f));

            animation.Duration = TimeSpan.FromSeconds(6);
            animation.IterationBehavior = AnimationIterationBehavior.Forever;

            visual.StartAnimation("Offset", animation);

So it grabs the image element "gimage" and moves it up and down. This works fine.

Now what I have is an ObservableCollection of this usercontrol in a gridview. This gridview is set to allow reordering of items. I can reorder an item on the same row it is on, but once I move it to another row in the grid, the application crashes with "An unhandled win32 exception occurred in appname.exe [7996]". If I disable the animations, this error does not occur and I can reorder all items on my gridview.

I would appreciate any feedback on this, I can't seem to work around it.

Thanks!

@shandilvarun Any updates on this issue?

@moc426 Are you still running into this issue? If so, what BUILD number are you using?

[moc426]

@pgills Yes the issue still exists, I am using build 10586.

I enabled native debugging and this is the message I get

0xC000027B was unhandled
Message: Unhandled exception at 0x0431A41E (Windows.UI.Xaml.dll) in app_name.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x0E7568E0, 0x00000001).

@moc426 I'll poke @shandilvarun to see if there has been any progress.

Hi @moc426 do you mind attaching a small app that repros this issue? if not then can you provide some more insights on how are you re-ordering and set of operations.

@shandilvarun

Sure attached is quick sample app I put together that reproduces the issue. You can run the application. Dragging the items on the same row works fine, once you drag to a different row, it will crash.

Thanks

@moc426 we have identified this as a bug and will update you once we have a fix in place. For now to workaround this issue is to use transitions (ReorderThemeTransition or ContentThemeTransition). Thanks for finding one for us.

Closing. If there are any issues with the workaround, please reactivate.
