Hello Everyone,

I want implement drag and drop through hoverButton of kinect.

public partial class MainMenu : UserControl

        float handY;

So far, I've done only click event, but I want to do like drag and drop, you click on a button and drag it, after that you put that button in another label or frame, holding it for 5 seconds, after that you drop it there. How can I do this, can you give me advice?
