DevExpress ASP.NET & HTML 5

Have you been using or experimenting with HTML5? You may have run into issues trying to use DevExpress controls in HTML5 documents because of doctype conflicts. We're happy to announce that these issues will be fixed in DXperience v2011 volume 1 release and you'll be able to use DevExpress ASP.NET controls in most HTML5 documents. And the support is cross browser so you can do it with Microsoft Internet Explorer 6.0+, Mozilla FireFox 2.0+, Google Chrome 1.0+, Apple Safari 3.0+, Opera 9.0+ and Netscape Navigator 9.0+ are fully supported.

Here are the technical details in case that you can take advantage of now with the DXperience v2011 volume 1 release:

The HTML5 and XHTML Strict standards support by DevExpress ASP.NET means that you'll have a choice of using 3 different doctype declarations:

  • XHTML 1.0 Transitional - Current
  • XHTML 1.0 Strict - v2011.1
  • HTML5 !!! - v2011.1

Why?

Several of you, our customers, had requested support for the XHTML Strict standard because of your project requirements.

So at our annual roadmap meeting in December 2010, we, the DevExpress ASP.NET team decided to add the HTML5 standard because HTML5 is the future!

Note: The code generated by DevExpress ASP.NET controls will be valid XHTML 1.0 Transitional and it will work just fine in the other doctypes. However, please note that if your doc is another doctype like HTML5, etc. the controls will work but if you check it with an HTML validator you'll probably see warnings due to the doctype conflict. It's nothing to worry about but we wanted to be clear.

MVC Project Templates - New Doctype(s)

For v2011 volume 1, we've updated our ASP.NET MVC DevExpress Project Templates to support:

ASP.NET MVC 2 - XHTML Strict

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

ASP.NET MVC 3 - HTML5

<!DOCTYPE HTML>

These doctypes match Microsoft's ASP.NET MVC Web Application Templates.

Cross-Browser Support

The DevExpress ASP.NET controls are already cross-browser compliant because they support the XHTML 1.0 Transitional standard. This means that you can use DevExpress ASP.NET controls with these popular browsers:

Microsoft Internet Explorer 6.0+, Mozilla FireFox 2.0+, Google Chrome 1.0+, Apple Safari 3.0+, Opera 9.0+ and Netscape Navigator 9.0+ are fully supported.

 

This announcement has me very excited, what about you?

Sorry, but I'm confused by the "Note" statement.

Leigh,

Thanks and sorry because I wasn't clear enough. I've updated the post and note section.

Also, the topic can be confusing, email me if you have other concerns.

This is a great read for HTML5: diveintohtml5.org/introduction.html

Thanks.

Do you mean only the ASP.NET MVC extensions get xhtml1 strict and html5 support, but the rest of ASP.NET Ajax controls don't?

M. Brekhof,

The HTML 5 and XHTML Strict is supported by both. But we only have project templates for MVC.

Thanks.

Hi Mehul

Do you have any idea when or if the controls will ever fully validate as HTML5?

Fergal,

Well.. HTML 5 is designed to be backwards compatible:

That said, we're always looking to improve our products when it makes sense. So, will we improve and take advantage of HTML 5, yes. :)

Thanks.

Hi Mehul

Thanks for that...

I just like the warm fuzzy feeling when my sites validate 100%

Fergal!
