The JS documentation for the new Grid component contains alot of classes and alot of inherited methods. For someone who is not very advanced with object-oriented development, it may seem complex or difficult to trace the various inherited methods through the class hierachy. It may also seem like the Grid is difficult to use. While most of the classes in the YAHOO.ext.grid package are designed to be plug and play, extended and customized, it still very easy to simply plug the grid into a webapp with a minimal amount of code.

To test the grid and to create an example implementation of the Grid in a real application, I decided to create a simple, single-page RSS feed viewer application. The entire application is under 100 lines of javascript code, of which maybe 20 are related to the grid. It gives a good example of some of the key features of the grid, such as AJAX loading, preprocessing and custom rendering.
