For data tables and secondary data sources, "Repeating Table" and other repeating controls are introduced. InfoPath provides several controls (e.g. textbox, radio Button, checkbox) to present data in the data source to end-users.
Secondary data sources can be built into the form or they can be accessed through an external data connection to SharePoint or a Web service. The form template must have one primary data source for submitting data and can have multiple secondary data sources for retrieving data into the form. According to Jean Paoli, one of its developers, a key architectural design decision was "to adhere to the XML paradigm of separating the data in a document from the formatting." A patent filed in 2000 by Adriana Neagu and Jean Paoli describes the technology as "authoring XML using DHTML views and XSLT." Īll the data stored in InfoPath forms are stored in an XML format, which is referred to as the "data source". In order to use InfoPath to fill in a form, a designer must develop an InfoPath template first.
