Zone Visual Elements
A dock zone is a place where panels can be docked.
Using a dock panel’s DockPanelSettings.ForbiddenZones property, you can specify disallowed zones for the panel - the zones to which the panel cannot be docked. It is also possible to provide different appearances for the allowed and forbidden zone states by using a dock zone’s DockZoneStyles.DockingAllowedStyle and DockZoneStyles.DockingForbiddenStyle properties. These appearances are used to highlight zones and to indicate whether a particular zone is allowed or disallowed for panel docking.
A Panel Placeholder is a zone section where the panel can be docked. Use the DockZoneStyles.PanelPlaceholder property to highlight this section during panel dragging.
The table below lists the main members that affect element appearance:
