TWebListInput is the base class for Web items that create HTML display controls which present a fixed set of possible values.
TWebListInput = class(TWebDataInput, IScriptComponent);
class TWebListInput : public TWebDataInput, public IScriptComponent;
Use TWebListInput as a base class for components that generate HTML controls for displaying a fixed set of possible values from which a user can choose. TWebListInput descendants generate controls that are organized by TDataGrid, TFieldGroup, or TQueryFieldGroup.
TWebListInput defines or inherits properties and methods for
Specifying a field or parameter whose value the control displays.
Specifying the possible values from which the user can choose.
Generating a caption that describes the information displayed.
Customizing the appearance of the control that displays information.
Fitting the control into the tab order of the generated HTML form.
Fitting the component into a hierarchy of Web items that collectively generate the content of an HTML document.
In order to let other Web items to use the HTML control it generates, TWebListInput inherits the IWebContent interface from TWebDataDisplay.
Do not create instances of TWebListInput. Instead, use a descendant of TWebListInput such as TFieldRadioGroup, TQueryRadioGroup, TFieldSelectOptions, TQuerySelectOptions, or TSelectOptionsColumn.
