Reordering items in a GridView with a VariableSizedWrapGrid

Question

Hello MSDN forums,

I'm trying to do something similar to this http://blogs.u2u.be/diederik/post/2012/03/07/Databinding-to-the-VariableSizedWrapGrid-in-Windows-8-Metro.aspx in which I can also reorder the items.

I've tried setting the GridView's AllowDrop, CanDragItems and CanReorderItems to true, which allows me to drag the items but I can't drop them. 

Everything works fine if the GridView's ItemsPanelTemplate is set to a regular WrapGrid instead of a VariableSIzedWrapGrid. Is there any issue with the VariableSizedWrapGrid in the current build?

Thanks!
Roberto

Hi Roberto - we've had others report this and unfortunately, this scenario is not supported for VSWG in Windows 8.

Matt,
    Is this something that is going to be supported in the future?  Or is there a way we can extend the control to add support for it?  In otherwords, what's missing from VariableSizedWrapGrid, that WrapGrid has that allows the reordering to occur?

Thanks,

-Jim

What's missing is some internal interface implementations.  You might be able to roll your own.  I don't know and can't say if it will be implemented in the future.
