TWebDisplayReferenceGroup is the base class for Web items that arrange a set of controls that influence a control that displays data.
TWebDisplayReferenceGroup = class(TWebControlGroup, IWebDisplayReference);
class TWebDisplayReferenceGroup : public TWebControlGroup, public IWebDisplayReference;
MidItems
Use TWebDisplayReferenceGroup as a base class for Web items that generate the HTML to arrange a collection of button controls. Each TWebDisplayReferenceGroup object has an associated Web item that generates controls that display data in the final HTML document. The controls arranged by TWebDisplayReferenceGroup manipulate the information the display controls show.
In order to let other Web items use the HTML that the TWebDisplayReferenceGroup object generates, TWebDisplayReferenceGroup inherits the IWebContent interface from TWebControlGroup.
Do not create instances of TWebDisplayReferenceGroup. TWebDisplayReferenceGroup manages the Web items that generate buttons and the association to a display generator, but does not produce any content. Instead, use a descendant of TWebDisplayReferenceGroup such as TDataNavigator (in InternetExpress applications) or TAdapterCommandGroup (in WebSnap applications).
