This is an implementation of Google Suggest like dictionary in ASP.NET
The architecture could be explained as outlined below:
Concept
The database
ASP.NET page
XMLHttpRequest object in the HTML page
As you type a word in the textbox, a JavaScript event fires an HTTP GET request to the ASPX page. The response from the ASPX page is simply displayed in a div tag under the textbox. The page is not refreshed/reloaded for every keystroke as everything is done by the JavaScript in the page. The main JavaScript object that allows us to do this is XMLHttpRequest.
