Description

When using the GroupedItemsPage example for a Windows Store App the horizontal scrollbar jumps around in a weird way when the groups have big differences in the amount of items hosted.

Hi Tim,

thank you for clarifying this! The workaround works like a charm.

Hi Simon,

Thanks for reporting the issue. "Closed as External" in this case means the issue is not one of Visual Studio but rather the underlying API platform not delivered by Visual Studio (e.g., Windows Runtime).

Unfortunately the issue you note is a known issue with virtualized items within grid/list view controls where we have a dynamically resizing scrollbar issue. As noted in the workaround that a user provided you can change to a StackPanel and will not have this issue but depending on your scenario might add a different challenge as the items will not be virtualized.

We are hoping to address this in a future release and are aware of the issue.

So what does "Closed as External" mean in this case? Even the sample in the SDK has this issue...

It seems as if it's the VirtualizingStackPanel in the itemGridView's ItemsPanelTemplate that is the root of this behavior.
Replacing it with a regular StackPanel makes the scrolling behave as expected. This workaround may impact performance if you have a large number of groups/items.
