This article does a great job at showing you a simple example of how to use local browser web storage in conjunction with ASP.NET web methods to save and retrieve the data from a server side database. Even if you aren’t interested in using this functionality in an application you have now, it’s worth reading to know what HTML5 brings to the table as far as storing your data down at the client.
Yay!! Microsoft has released a Web Standards Update for Visual Studio 2010 that adds full support for HTML5, CSS3 and new Javascript features like Geolocation and local storage. Scott Hanselman has a good write-up on this update in this blog post. There you can see some more detail about what exactly it brings to the VS.NET IDE, etc. Or, if you want to skip all that and go right to the download, you can get it here. At this point in time the HTML5 standard is still evolving. Taking that into consideration, Microsoft plans to provide additional updates every quarter or so to keep up with new features, changes to the draft, etc.
By the way, if you still aren’t familiar with all of the cool things that HTML5 brings to the table you should definitely check out this free online book, Dive Into HTML5, by Mark Pilgrim.
I have been doing some work lately with jQuery, WCF, HTML5 and ASP.NET and it’s been actually pretty fun challenging and fun. I’ve gotten to tinker with quite a few new technologies that I hadn’t used before and really got to sink my teeth into jQuery and some of the cool new features that HTML5 has to offer (like local storage and offline capabilities).
When starting out with my recent project I had to pull from various resources to learn what these tools were capable of and how I could fit them all together. And while it doesn’t get into the HTML5 aspects of my project this article on creating a simple task list with ASP.NET, WCF and jQuery would have been very helpful to me in the beginning.
While the article is only Part 1 in a series, I think it will get you going in the right direction and will show you some of the power that you have on the client with the new jQuery data templates. I must say that with the introduction of these templates you can truly offload a large amount of your logic down to the client which will provide for a much better (and faster) user experience.
Anyway, check out the article. It’s short, to the point and offers the source code as a download too!
