How to make a usercontrol with moveable controls

I have created a usercontrol containing as textbox and a picturebox.

I have added a couple of my usercontrols to a winform. In the winform
design-mode I would like to be able to move the textbox and/or the
picturebox within the usercontrol. Is that possible???

At the moment I can only select the usercontrol itself but not select
any of the controls inside the usercontrol.
