- At design time
- At run time

The docking manager allows to reorder the tab by selecting and dragging to the desired index in
DockTabControl. Tabs reordering behavior can be enabled or disabled by using the AllowTabsMoving property.
// Prevent the tabbed controls from moving this.dockingManager1.AllowTabsMoving = true;
