"Normal" WPF layout model is not designed to move things freely (thanks goodness!). One thing you can do it to put your button on Canvas:

This class of Panel is different from others, it is designed for free positioning, which you can modify using the following methods:
http://msdn.microsoft.com/en-us/library/system.windows.controls.canvas.setleft.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.controls.canvas.settop.aspx[^].

To implement dragging, you will need to handle mouse events of Button:

Solution 1

WPF buttons have a MouseEnter event. Add an event handler - when this event is hit, move the button. It's incredibly straightforward.

Not so apparent for the beginner. It depends what is the parent of the Button, and also related to dependency properties. For many people with System.Windows.Forms experience, this is quite mind-bending.
I explain it in my answer, please take a look.
