Is Ajax a technology platform or is it an architectural style?

Posted By :Akhil Raj     Posted Date :August 27, 2009    Points :10   Category :Others 
Its both. Ajax is a set of technologies being used together in a particular way.

You can also find related Interview Question to Is Ajax a technology platform or is it an architectural style?  below: 

Can I use ASP.NET AJAX with any other technology apart from ASP.NET?

To answer this question, check out this example of using ASP.NET AJAX with PHP, to demonstrate running ASP.NET AJAX outside of ASP.NET. Client-Side ASP.NET AJAX framework can be used with PHP and Coldfusion. (More...)

What are the disadvantages of AJAX?

The disadvantages are:
a)Ajax is not so friendly with search engine indexing because it uses Javascript for much part of its code. Search engines generally do not index Javascript present in web pages.
b)Dynamically created pages created by ajax does not support back button which takes the user to the previous pages. (More...)

Can we run DOT.NET in UNIX platform?

One of the disadvantages of using Visual Studio.NET and the .NET framework to develop applications has been the lack of cross-platform support. Since the introduction of the .NET framework and common language run time a few years ago, there have been a few projects designed to bring the .NET framework to other platforms, including Linux and UNIX. The DotGNU project is touted as the "Free software alternative to .NET" and encompasses a number of projects, including DotGNU Portable .NET, which is designed to be used to compile and run C# and C applications on a multitude of platforms, including GNU/Linux, FreeBSD, Mac OS X, and Windows.One of the main features of the product is it's compatibility with EMCA standards for C# and the Common Language Infrastructure (CLI), as well as Microsoft's own CLI implementation in the .NET framework. The project chose to go with a "Virtual Machine" implementation, where bytecode is transformed into a simple instruction set which is then
passed to a "Converted Virtual Machine", which then are executed through an interpreter. This approach is different to other open source .NET implementations, but provides more flexibility
when porting the project to other platforms.At the core of the project is the runtime engine (ilrun) and compiler (cscc) with an implementation of System.Windows.Forms that make developing for the platform easier, as it doesn't required translation through another toolkit or toolset. (More...)

Is the ASP.NET AJAX Control Toolkit(AjaxControlToolkit.dll) installed in the Global Assembly Cache?

No. You must copy the AjaxControlToolkit.dll assembly to the /Bin folder in your application. (More...)

What is the role of the ScriptManager control in implementing multilingual applications (AJAX)?

The ScriptManager control can be used to define the UI or custom UI cultures that you would use in your applications. You can set the
EnableScriptLocalization and EnableScriptGlobalization properties of
the ScriptManager control to true and specify the script reference path as per your requirements. (More...)

Explain the disadvantage of ajax related to browser integration?

Dynamically created pages created by ajax does not support back button which takes the user to the previous pages. There are various solutions to this problem out of which one solution is to use iframes. Also users can bookmark a certain application in its state. User can maintain the applications as the state of the application changes (More...)

Explain about security of the Ajax based web applications?

The XMLHttpRequest object is subjected to the browsers security sandbox. Any resources requested by the XMLHttpRequest object must reside within the same domain from which the calling script originated from which the calling script requested. XMLHttpRequest cannot request services due to security restriction, outside the domain from which the script was originally served. (More...)

What is ChildrenAsTriggers ,and to which control it belongs? (AJAX)

When the ChildrenAsTriggers property is set to true and any child control of the UpdatePanel control causes a postback. Child controls of nested UpdatePanel controls do not cause an update to the outer UpdatePanel control unless they are explicitly defined as triggers for the parent panel. (More...)

How do you invoke a web method of web service in AJAX?

In order to use a webmethod of a webservice, we need to add the reference of webservice in the section of ScriptManager. Under services you have to configure the servicepath.

< asp:ScriptManager ID="ScriptManager1" runat="server">
< Services>
< asp:ServiceReference Path="..\service1.asmx" />
< /Services>
< /asp:ScriptManager>

Inside JAvascript Use methods of this service directly like
service1.methodname() (More...)

What Is AJAX?

AJAX = Asynchronous JavaScript and XML

AJAX is not a new programming language, but a technique for creating better, faster, and more interactive web applications.

With AJAX, your JavaScript can communicate directly with the server, using the JavaScript XMLHttpRequest object. With this object, your JavaScript can trade data with a web server, without reloading the page.

AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages.

The AJAX technique makes Internet applications smaller, faster and more user-friendly.

* AJAX is a browser technology independent of web server software.
So you dont have to worry about the Server Side Technology when implementing AJAX in your Web Applications

What is Ajax? What is ASP.NET AJAX?

What is Ajax?

The term Ajax was coined by Jesse James Garrett and is a short form for "Asynchronous Javascript and XML". Ajax represents a set of commonly used techniques, like HTML/XHTML, CSS, Document Object Model(DOM), XML/XSLT, Javascript and the XMLHttpRequest object, to create RIA's (Rich Internet Applications).
Ajax gives the user, the ability to dynamically and asynchronously interact with a web server, without using a plug-in or without compromising on the user's ability to interact with the page. This is possible due to an object found in browsers called the XMLHttpRequest object.


'ASP.NET AJAX' is a terminology coined by Microsoft for 'their' implementation of AJAX, which is a set of extensions to ASP.NET. These components allow you to build rich AJAX enabled web applications, which consists of both server side and client side libraries.
Which is the current version of ASP.NET AJAX Control Toolkit?
As of this writing, the toolkit version is Version 1.0.20229 (if you (if you are targeting Framework 2.0, ASP.NET AJAX 1.0 and Visual Studio 2005) and Version 3.0.20229 (if targeting .NET Framework 3.5 and Visual Studio 2008). (More...)

Difference between Server-Side AJAX framework and Client-side AJAX framework?

ASP.NET AJAX contains both a server-side Ajax framework and a client-side Ajax framework. The server-side framework provides developers with an easy way to implement Ajax functionality, without having to possess much knowledge of JavaScript. The framework includes server controls and components and the drag and drop functionality. This framework is usually preferred when you need to quickly ajaxify an asp.net application. The disadvantage is that you still need a round trip to the server to perform a client-side action.
The Client-Side Framework allows you to build web applications with rich user-interactivity as that of a desktop application. It contains a set of JavaScript libraries, which is independent from ASP.NET. The library is getting rich in functionality with every new build released. (More...)

Explain differences between the page execution lifecycle of an ASP.NET page and an ASP.NET AJAX page?

In an asynchronous model, all the server side events occur, as they do in a synchronous model. The Microsoft AJAX Library also raises client side events. However when the page is rendered, asynchronous postback renders only the contents of the update panel, where as in a synchronous postback, the entire page is recreated and sent back to the browser.
