Accessibility Compliance
In conformance with the W3C Web Accessibility Guidelines 1.0 Telerik RadGrid is "Level A" content compliant.
Accessibility features for grid images:
- 'alt' attribute for all images (applies only for images as a part of the grid content. Alt attribute for the Telerik RadGrid control images (sort images, expand images) is not available for setting) - For user agents that cannot display images, this attribute specifies alternate text.
Accessibility features for GridTableView:
- 'summary' attribute - GridTableView.Summary - It sets the 'summary' attribute for the respective table. This attribute provides a summary of the table's purpose and structure for user agents rendering to non-visual media such as speech and Braille.
- <caption> tag - GridTableView.Caption - It sets the <caption> tag for the current <table>.
Visual user agents allow sighted people to quickly grasp the structure of the table from the headings as well as the caption. A consequence of this is that captions will often be inadequate as a summary of the purpose and structure of the table from the perspective of people relying on non-visual user agents.
Authors should therefore take care to provide additional information summarizing the purpose and structure of the table using the Summary attribute of the element. This is especially important for tables without captions.
- 'frame' attribute - GridTableView.Frame - sets tips and visibility for table borders.
Other accessibility features:
- Keyboard support - Telerik RadGrid support navigation, selection and enter in edit mode using the keyboard.
- Telerik RadGrid renders header cells in the header row
- Telerik RadGrid renders 'thead', 'tfoot' and 'tbody' elements

Section 508
The USA federal mandate requiring that information technology be made accessible to people with disabilities. Much of Section 508 compliance concerns making Web sites, intranets, and web-enabled applications accessible. Section 508 compliance has since become a major prerequisite not only in government related software, but also in most enterprise and corporate software solutions.
W3C Web Content Accessibility Guidelines 1.0
The main goal of these guidelines is to encourage developers in creating applications providing accessible content. However, adhering to these guidelines will also make Web content more available to all kind of users, using different devices and interfaces: desktop browser, voice browser, mobile phone, automobile-based personal computer, etc.
In accoradnce with these quidelines W3C defines three levels of conformance В developer may implement inorder to provide some level of content compliance to their products:
- Conformance Level "A"
- Conformance Level "Double-A"
- Conformance Level "Triple-A"
For more details on W3C Web Content Accessibility Guidelines 1.0 see http://www.w3.org/TR/WAI-WEBCONTENT.
In our attempt to make our products content compliant, each web-control we develop and its Quick Start Framework should strive to obtain at least one of conformance levels listed above. |

Telerik RadGrid provides complete XHTML 1.1 compliance, with the following exceptions:
- GridCheckBoxColumn is not XHTML compliant. By default it is ReadOnly and .NET Framework renders:

What is XHTML
