actually i just want the user to be able to drag it to anywhere, but not into another form or panel. in essence i just want to make the panel mobile.

Well surely you want the panel to do something once you stop dragging?
If you don't you might as well just make it its own borderless form and treat it as dockable when and if required.

so is that really the only option? to make it a form? i already have speed buttons on it with functionality that references other forms etc. in the application so it seems like it would be easier to give it (the panel) the ability to be dragged and dropped (to any where) and docked when needed. It already docks and undocks on a double click. i just want to be able to move it when it is undocked. I imagine some code on the OnMouseDown or OnDragOver would do it,..i was just looking for some samples/suggested code.

Well a panel cannot exist in its own right I would think, only a form.
It shouldnt be too hard to retro fit it onto a borderless form though, no need (or very little) to alter the code you already have, just drop the panel on the form and set it to the form size.
