Hi Scott,
A Standard Form can be docked to the MDI Window by using the SetEnableDocking() method of the DockingManager.
this.dockingManager1.SetEnableDocking(frmChild,true);
For this to work, you have to set the following properties to the Child form.
frmChild.TopLevel = false;
frmChild.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
Here is the link of the KB which explains the same.
