This looked interesting so I thought I would share it.

Please let me know what you think.....

From the CodePlex Description.

The Ajax Data Controls is a DotNetSlackers project. Developed on top of Asp.net Ajax Extension, the main goal of this project is to provide rich set of data controls for Client Centric Development Model. Since the data controls of Asp.net like GridView, DataList, Repeater etc does not have any Client Side Object Model thus it is not possible to work with these controls with Web Service / Page Methods call. The included controls exposes same API in the client side as the Asp.net version with few more enhancements. Currently the project contains the following controls:

• Repeater
• GridView
• DataList
• Pager

If you reference an ASP.NET page that contains a scriptmanager in your js file like below you get intellisense for the entire Microsoft AJAX Library plus any additional scripts ref’d by the scriptmanager.  The easiest way to get the /// <reference/> entry in your js file is to drag n drop your .aspx page from solution explorer into  the contents of your js file.  VS magically adds the refJ

Since I tend to use stand-alone .js files I can just add this.

/// <reference name="MicrosoftAjax.debug.js" />

to my consuming page and intellisense is wired to my JavaScript code.
