Given the amount of client side content that is going to be knocking around in Visual studio 2008, I’d say it’s a good time to brush up on your jscript skills. While you are at it, make sure you check out this library to give you a leg up. Communication between jQuery and ASP.NET is a breeze and as a quick example, this is what you need to get inline editing going with very little effort at all.

You will need:
jQuery
jEditable

First the .aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">
<title>Untitled Page</title> 
<script src="jquery.js" type="text/javascript"></script> 
<script src="jeditable.js" type="text/javascript"></script> 
<script type="text/javascript">$(document).ready(
function(){ $("p").editable( "http://localhost:3684/test/handler.ashx", { type: 'textarea',cancel: 'Cancel',indicator:"test.jpg", submit:'ok'});
});</script>
 </head>
<body>
<form id="form1" runat="server">
<div>
</div>
<p>yes you are now rocking with the best</p>
</form>
</body>
</html>
 

and you will need a httphandler to save the edits. For this example, I’m just writing the data back out without storing it.

<%@ WebHandler Language=“C#” Class=“handler” %> using System;using System.Web; public class Echo : IHttpHandler {public void ProcessRequest (HttpContext context) {context.Response.ContentType = “text/plain”;context.Response.Write(context.Request.Params["Value"]);}public bool IsReusable {get {return false;}} }

 

And that’s it. Inline editing with jQuery and ASP.NET. Simple!

PS if you want to know why there has not been much action on the blog this month, blame this.

I’ve got to say, that when it arrived, it was a bit of a shock. This is the thinnest technical book I’ve ever bought, compared with other Wrox publications it just looks puny!

To be honest, a lot of the content is a bit puny too. Maybe it’s just me being a bit to eager, but i already knew about 75% of the content just from my Internet based studies. The chapter of the AJAX Toolkit is particularly thin and doesn’t cover anywhere near as much functionality as one would expect.

On the other hand, the chapters on debugging and testing, deployment and building AJAX based customer controls are particularly illuminating. To sum up, I’d say this was a decent introduction to the subject, but not something that deserves a ‘Professional’ title added to it. A half decent weekend read, 6 out of 10. More at Amazon.co.uk…

My main frustration with the old libraries was that the system threw a wobbler if you tried to use it in conjunction with one of the shockingly good pre-built javascript libraries such as prototype or scriptaculous.
It’s good to see that Microsoft has gone a long way to code their way around code base clashes and are a member of the OpenAjax Alliance, dedicated to interoperability amongst libraries.
Anyway, here’s a brand new how-to video that has only just appeared on the official AJAX.ASP.Net site.
