This can be done using the below code snippet.
private void InitializeDockControlState()
{
this.dockingManager1.FloatControl(this.myUserControl11, new Rectangle(250, 250, 220, 260));
this.dockingManager1.FloatControl(this.myUserControl21, new Rectangle(350, 350, 220, 260));
this.dockingManager1.DockControl(this.myUserControl31, this, DockingStyle.Right, 200);
this.dockingManager1.DockControl(this.myUserControl11, this.myUserControl21, DockingStyle.Bottom, 200);
}
private void GetDockingRelationship(Control dockedControl)
{
