RSS (Really Simple Syndication) Feeds are becoming very popular these days. People need Country News at their own commercial websites. Today the most powerful websites are being developed in ASP.NET due to the fact that ASP.NET provides Web Controls that enable the Software Reuse property of Software Engineering Models. RSS Reader Control may be just dragged and dropped on web forms, can be linked to an RSS Feed and it will display a smooth, cool, and scrolling interface to the Feeds.
The main power behind creation of such feeds is XML (Extensible Markup Language). XML is a structured language, thus provides support for the structured sharing of data. XML documents are built under a specific format. An example of such a document is as follows:

Using the Code
To use RSS Reader, you will need to add RSS Reader to your tool box by locating the RSSReader.dll. Once RSS Reader is in your tool box, you will need to drag it to the page. You will also need to provide the URL where to fetch news from. Different CSS classes may also be applied for a good interface of the control. Since the header, content area, and footer are purely editable and styleable, you will have the option to design the control to your requirements and likings. The list of properties is as follows:
HeaderText: The Text to appear as the control title, e.g. Country News
HeaderCssClass: The CSS Class to apply on Header
RSSHeading: The Text to appear as heading for the news inside the control, e.g. News
