Hi Andy,
Thank you for your interest in Syncfusion Products.
Docked control can be docked to any of the four sides of the container control. i.e., to Left, Right, Top and Bottom. DockingManager lets you specify the type of docking and the bounds of the docked control using the DockControl method.
Please refer the below code.
[C#]
this.dockingManager1.DockControl(this.panel1, this, Syncfusion.Windows.Forms.Tools.DockingStyle.Left,100);
this.dockingManager1.DockControl(this.panel2, panel1 , Syncfusion.Windows.Forms.Tools.DockingStyle.Bottom,200);
Please refer the tutorial link for more detail.
