Implementation Details:
We have improved the rendering of our controls so that they look and behave properly and uniformly within webpages using one of the following document types:
- XHTML 1.0 Transitonal
- XHTML 1.0 Strict
- HTML5
Support for these doctypes applies across browsers, so our web controls appear and work identically under all supported browsers including 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+.
Note that the code generated by DevExpress ASP.NET controls is mainly designed to comply with the XHTML 1.0 Transitional specification. In other supported document types our code works well, but may not fully pass the markup validation.
Known problems: the following elements that are considered invalid are used:
- For XHTML 1.0:
- the align attribute
- the iframe tag
- the embeded tag (it is used in ASPxObjectContainer)
- For HTML5:
- align and valign attributes
- " " and "…"
- CellSpacing and CellPadding attributes
- the scrolling attribute within the iframe element

At present we support XHTML 1.0 Transitional. See the following link:
DevExpress ASP.NET AJAX Controls XHTML 1.0 Transitional Support
Transitional DOCTYPE meets the modern requirements and there is no necessity to use Strict DOCTYPE.
The Strict doctype has a number of limitations which may break the functionality of our controls.
