DockableControlPane dcpAppView;
DockableControlPane dcpDocsView;
DockableGroupPane dgpGroup;
DockAreaPane dapControls;

UsrCntrlApplicationPanel usrApps = new UsrCntrlApplicationPanel();
dcpAppView = new DockableControlPane("apps", "Applications", usrApps);
usrApps.BringToFront();
dcpAppView.MaximumSize = new System.Drawing.Size(200, 400);

UsrCntrlDocumentPanel usrDocs = new UsrCntrlDocumentPanel();
dcpDocsView = new DockableControlPane("Documents", "Documents", usrDocs);
usrDocs.BringToFront();
