The ConformOnFormSubmit property determines whether or not the confirm dialog box should wait when the form is submitted for display.

AJAX uses the following syntax to create an object:

var myobject = new AjaxObject("page path");

The page path is the URL of the Web page containing the object that you want to call. The URL must be of the same domain as the Web page.

Extensible HTML (XHTML) is a markup language that provides the mixture expressions of HTML and XML. XHTML is a flexible markup language that enables automated processing by standard XML tools, which was difficult in HTML.

AJAX is a built-in functionality of .NET Framework 4.0. Therefore, you can run an AJAX application by just installing Microsoft Visual Studio 2010. However, to use extenders in your applications, you are required to install AJAX Control Toolkit and copy the AjaxControlToolkit.dll file to the Bin directory of your application.

You should not use AJAX if:
• You want the page to show in a search engine, such as Google, because WebCrawler does not execute JavaScript code.
• The browser does not support JavaScript.
• You want to create a secure application.
