Description
TXMLDisplayGroup is the base class for Web items that arrange a set of special-purpose controls in an HTML form.
Use TXMLDisplayGroup as a base class for Web items that generate the HTML to arrange a collection of HTML controls. Each TXMLDisplayGroup object maintains a list of Web items that display information in the final HTML document. The XML display group arranges the controls that these items generate.
If the controls generated for TXMLDisplayGroup by its Web items represent database information, you can bind the XML display group to an XML data packet or dataset field within an XML data packet. The Web items can use that binding to determine the source of the data they display.
In order to let other Web items use the HTML that the TXMLDisplayGroup object generates, TXMLDisplayGroup inherits the IWebContent interface from TWebControlGroup.
Do not create instances of TXMLDisplayGroup. TXMLDisplayGroup manages the Web items that generate display controls, but does not produce any content. Instead, use a descendant of TXMLDisplayGroup that generates the HTML for its set of specialized controls such as TDataGrid, TFieldGroup or TQueryFieldGroup.
