Arrange the RadDocks from the RadDockZone above in the RadDockZones below.
If you hover the correct RadDockZone, it will be highlighted.

  • HighlightedCssClass

    While dragging a RadDock, if a RadDockZone is hovered over, the RadDockZone gets highlighted. With RadDock it is possible to specify the highlighting style for each docking zone using the HighlightedCssClass property.

    1) If the HighlightedCssClass is set, for example: RadDockZone.HighlightedCssClass="CustomCssClass", the css class HighlightedStyle will be applied to the RadDockZone when the zone is highlighted.

    2) If the HighlightedCssClass is not set, the RadDockZone will not be highlighted while dragging a RadDock over it.
