How to fill the entire client area of host control with docking windows in WinForms Docking Manager?

Platform: WinForms |
Control: DockingManager |
Published Date: April 30, 2011 |
Last Revised Date: December 5, 2019

Enable docking behavior

DockingManager has a bool property called DockToFill to achieve this behavior. If this property is set to true DockingManager will fill the entire available client area with docked controls. Please refer the below code snippet which illustrates this:


this.dockingManager1.DockToFill = true;



Me.DockingManager1.DockToFill = True

The DockToFill option is not valid when the host form is an MDIContainer.
