About working with Web Parts
A Web Part is a modular unit of information that contains Web-based content and is the building block of a Web Part Page. A Web Part is made up of several component files that store the data and information necessary to render the Web Part.
When you add Web Parts to your page by using Microsoft FrontPage, you have more control over how they appear than you would by working with them in a Web browser. You can also create connections between Web Parts so that when you perform an action in one Web Part, it changes the contents of another Web Part.
About Web Part connections In Web sites located on Web servers running Microsoft Windows SharePoint Services, the types of data sources that you can use include Extensible Markup Language (XML) files, Web services, and SharePoint lists. Connecting sets of data from different data sources usually requires advanced programming skills, but by connecting Web Parts, you can pass data between them and synchronize their behavior.
For example, you can connect a List View Web Part, which contains a column with a hyperlink data type, to an Image Web Part, which contains a picture of an employee. Each time you select a row in the List View Web Part, you can see the picture of the employee displayed in the Image Web Part.
Although you can establish a Web Part connection by using the Web browser, by using FrontPage, you can extend the functionality of Web Part connections. For example, you can use the Form Web Part to filter the data in another Web Part, or you can establish connections between Web Parts on two Web Part Pages in the same top-level Web site.
By using the Form Web part in FrontPage, you can extend the functionality of Web Part connections by enabling site visitors to enter data through familiar form interfaces, which pass data into a Web Part connection.
For example, by using FrontPage to connect the Form Web Part to another Web Part capable of filtering through a Web Part connection, such as the List View Web Part, you can enable your site visitors to filter the data in the list by using an interface that is similar to a search box.
