| AJAX using ASP.NET |
| AJAX stands for Asynchronous JavaScript and XML. AJAX is a free framework which helps us to quickly create a new generation of more efficient, more interactive and highly – personalized web applications that works across all popular browsers. |
|
| On of the most significant advantages of using the AJAX frame work is that Web pages designed using these technologies do not require to be refreshed to update the information on it. Instead what happens is that the Ajax application simply updates parts of the page at any given instead of time, giving users an instantaneous response to their inputs and queries. With its integrated, multi-browser support, uniform client programming model and powerful server controls, incorporating AJAX functionality into Web sites, big or small, is now more simpler than ever before. |
|
| Some uses of AJAX technology: |
| Refreshing Data: |
| Web pages often require data from a server for displaying up –to – date details like for example live updates of cricket match scores or application specific data. Using AJAX web based application techniques a client may fetch a set of the current data with out having to reload the whole page. |
|
| Form Data Validation: |
| Form data validation is made simpler using AJAX web based application techniques by ensuring that data entry of fields like User IDs, serial numbers, postal codes, or even special coupon codes and other such data that has to be filled in forms is allowed to be entered only in the correct format there by pre-empting the need for server side validation before the user submits the form. |
|
| Auto-filling: |
| Certain fields of data such as an email address, name, or city name can be made to automatically populate their respective fields within the form. |
|
| Load on Demand: |
| As this technology allows the HTML page to fetch more data in the background, there is a remarkable decrease in the time required to load a particular page. |
|
| User interface controls and effects: |
| Certain controls like menus, data tables, rich text editors, calendars allow better user interaction and interaction with HTML pages, generally without requiring the user to reload the page. |
|
| This coupled with support of Visual Studio 2005 which allows you to take your ASP.NET 2.0 site to the next level with the option of creating next generation interfaces using re-usable AJAX components makes it a very attractive proposition to use this free frame work. |
