Is there a way to access the radial menu?

I looked through the API but found no references to the radial menu. Is this popup accessible?

No, the radial menu is not implemented in the API.

Thank you. Any ideas on how to manually work around this by dragging the mouse? I saw some examples where replacement Rectangles were given a mouse commands. Perhaps some sort of a hack with MouseDragAndDrop?

You can drag and drop and you can do this supplying viewport coordinates instead of an UIElement. For the latter part you should take a look at the sample at

I have no idea though how drag and drop would be connected to reading of the radial menu.

I figured if it clicks and drags, that’s all you need for radial. I’ll try it out. Thanks.
