Semantic zoom when zoomed in view is not a GridView or a ListView?

Question

I have a home screen that is basically a stack panel of 6 user controls that are all individual lists in slightly differant formats. It is clear that even with the way this data is presented a zoomed out view would be very applicable. Because I am using mutliple data sources in multiple view shapes I cannot use a GridView and hence I cannot put this inside a semantic zoom tag. Why do we have such a limitation and how can I get around it? Why can't semantic zoom just flip between two different views regardless of what they are?

Answer 1

If we check the definition of "GridView" on http://msdn.microsoft.com/library/windows/apps/BR242705 , it says :-

public class GridView : ListViewBase,ISemanticZoomInformation

So, in case if you would want your ItemsControl to have this functionality, then you can implement the "ISemanticZoomInformation" interface on it to add Zoom-in and Zoom-out functionality on custom controls.

Actually, SemanticZoom does not restrict from using any UI control as long as it implements ISemanticZoomInformation interface. Out of box just two WinRT controls implement this interface – GridView and ListView – but you are able to create your own control and use it with SemanticZoom.

bcollin,

I implemented a custom Stackpanel with supports Sematic zoom. Please not that this is very basic implementation.http://blogs.msdn.com/b/going_metro/archive/2012/07/18/semantic-zoom-only-supports-gridview-and-listview.aspx

Hope this helps.
