Let's look at an example where we use a Windows form to create three dockable panels on the bottom, top, and left sides of the container panel. Here is the definition of the container panel:

  basePanel= new Panel;
  basePanel.Location= new Point(0,0);
  basePanel.Size= new System.Drawing.Size(500,300);
  basePanel.Name= "basePanel";
  basePanel.Anchor= AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Bottom;

  leftPanel= new Panel;
  leftPanel.Location= new Point(0,0);
  leftPanel.Size= new System.Drawing.Size(100,300);
  leftPanel.Name= "leftPanel";
  leftPanel.Dock= DockStyle.Left;
  leftPanel.BorderStyle = "Fixed3D";

  topPanel= new Panel;
  topPanel.Location= new Point(100,0);
  topPanel.Size= new System.Drawing.Size(400,200);
  topPanel.Name= "topPanel";
  topPanel.Anchor= AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Bottom;
  topPanel.BorderStyle = "Fixed3D";

  bottomPanel= new Panel;
  bottomPanel.Location= new Point(100,200);
  bottomPanel.Size= new System.Drawing.Size(400,100);
  bottomPanel.Name= "bottomPanel";
  bottomPanel.Anchor= AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Bottom;
  bottomPanel.BorderStyle = "Fixed3D";

  basePanel.Controls.Add(topPanel);
  basePanel.Controls.Add(bottomPanel);
  basePanel.Controls.Add(leftPanel);
