Web applications that employ AJAX techniques are now very popular because of the great responsiveness they give to web/browser based applications. Howerver, programming AJAX applications typically adds a significant level of complexity, skill required and time to the development process. Alpha Five (V9) PLATINUM now comes with an extensive JavaScript library that GREATLY cuts the time and simplifies the development of Web applications that employ AJAX techniques.

Watch Videos Demonstrating AJAX Examples in Alpha Five (v9) PLATINUM.

This first video demonstrates the basic principle behind AJAX programming techniques. It shows how a piece of data can be submitted to a the server and a response can then be sent to the browser to update part of the page. Watch video. http://www.alphasoftware.com/VideoNe...dingBasics.swf
The second video demonstrates how AJAX techniques can be used to validate the data in a form. When the form's Submit button is pressed, data in the form is sent to the callback page and validated. Errors are written back to the page, and are displayed without a page reload. Watch video. http://www.alphasoftware.com/VideoNe...Validation.swf
The third video demonstrates how AJAX techniques are used to implement cascading dropdown boxes. We show a form with a State, City and Customer dropdown box. When the user selects a state, the city dropdown box is dynamically repopulated, and when the user selects a city, the customer dropdown box is repopulated. When the user selects a customer, the customer information is displayed on the page, where it can be updated and saved. Watch video. http://www.alphasoftware.com/VideoNe...ropDownDBF.swf
Next, we demonstrate how you can use AJAX to implement 'suggestion' lists as the user types into a textbox. We show how, as you type a name into a city field, AJAX callbacks can be used to present a list of cities that start with the characters you have typed. The video also shows filtered suggestions - where the suggestion list is filtered by the value in some other control you set on the page. Watch video. http://www.alphasoftware.com/VideoNe...SuggestDBF.swf This next video shows the same techniques, but this time using SQL Server as the data source for the suggestion list.

Finally we demonstrate a tutorial page that is intended to highlight the basic building blocks of an AJAX application. Several of the functions in the Alpha Five Ajax Form library are discussed.
