Hi Feminella,
It is possible tp programmatically create any docking layout that can be created using the designer. You could dock two controls as per your specifications above by using this code below :
this.dockingManager1.DockControl(this.panel1, this, DockingStyle.Left, 150);
this.dockingManager1.DockControl(this.listBox1, this.panel1, DockingStyle.Bottom, 150);
Assume that panel1 and listBox1 are two controls that you wish to dock. A
complete sample illustrating this is attached here. Please refer to the sample and let me know if you need any additional information.
