how to synchronize WinRT render and directX render

[xlazom00]

Anybody try to synchronize WinRT render(silverlight or whatever it is) and directX render(in DrawingSurfaceBackgroundGrid)
I what to draw some elements over directX but it is not synchronized(if I set up position for some UI element it isn't rendered(swapped to display) in same time as my background )

Can you provide a small sample for the scenario you are having issues with? I fail to see why you would have any problems in combining XAML + DirectX.

set up UI in XAML and try to move objects in silverlight (set up X,Y) and in same time do something similar in your DirectX
And try to synchronize position on object in silverlight and one in directX.
As silverlight is render engine it is impossible to synchronise anything with you render engine in directx as we don't have source codes.
in my situation picture of sun in sivlerlight and another sun my directX engine

Aha, I see. But why would you want to do that? For collision detection or?
