Click to view full-size image. Utilizing the example we just constructed, we can take a look at what ASP. We will also use the. Both of these tools are freely available online, and can be found with an internet search.

If you inspect the DOM tree in FireBug, you will notice that the labels are dimmed to indicate that they are not producing visible content. Click the Update This Panel button, and notice the top UpdatePanel will be updated with the current server time. In FireBug, choose the Console tab so that you can examine the request.

Examine the POST request parameters first:. Now, click on the Update Both Panels button. Then, examining the response, we see a pipe-delimited series of variables set in a string; specifically, we see the top UpdatePanel, UpdatePanel1 , has the entirety of its HTML sent to the browser.

Now, click on the Update Both Panels button and examine the results from the server. As with the previous callback, additional page state is sent. As we can see, because no special code is utilized to perform an AJAX postback, the AJAX client script library is able to intercept form postbacks without any additional code.

Server controls automatically utilize JavaScript so that they do not automatically submit the form - ASP. NET automatically injects code for form validation and state already, primarily achieved by automatic script resource inclusion, the PostBackOptions class, and the ClientScriptManager class. For instance, consider a CheckBox control; examine the class disassembly in. NET Reflector. To do so, ensure that your System.

Web assembly is open, and navigate to the System. CheckBox class, opening the RenderInputTag method. Look for a conditional that checks the AutoPostBack property:. NET event handling script in its onclick attribute. The interception of the form's submission, then, allows ASP. NET AJAX to be injected into the page nonintrusively, helping to avoid any potential breaking changes that might occur by utilizing a possibly-imprecise string replacement.

Furthermore, this enables any custom ASP. NET AJAX client script library utilizes the convention that methods, events, and field names that begin with an underscore are marked as internal, and are not meant for use outside of the library itself.

With it, we can observe which controls are intended to cause AJAX postbacks. For example, let's add two additional controls to the page, leaving one control outside of the UpdatePanels entirely, and leaving one within an UpdatePanel. Here is the new markup:.

UpdatePanel Let's learn a few lines about Update Panel. It's nothing but a region that will be updated in asynchronous operations. And this is the beauty of AJAX. The contents of the UpdatePanel will be updated and the outside content will remain the same.

Before writing any code related to ajax ypu need to put a ScriptManager tag in the aspx page. Let's see one example in action. The following will print the time within an Update Panel:. But the first label is First Time display as it is. OK, you are saying , "this is a very simple example and it's not at all useful in project development".

Then I will show you something more useful than this. Let's make a little database operation by AJAX technique. The basic concept or implementation is the same. Are there any tutorials using JQuery to Insert, Update, Delete and reterive records Single record and multiple records for datagrid etc?
