In this chapter, you learned how to implement a more complex screen to manage the inventory information from the database. You learned to handle a many-to-many association as well. You learned how to use some different form fields and how to do a Live Search. You also learned how to save data from a session.

In the next chapter, we will learn how to add some extra capabilities that are not native to the Ext JS API to the screens we have already developed so far, such as print, export to Excel, and export to PDF, the contents of a GridPanel. Also, we will learn how to implement charts and export them to images and PDFs.
