Compliance Level
- Telerik RadTreeView is "Level A" content compliant (in accordance with the W3C Web Accessibility Guidelines 1.0).
- Telerik RadTreeView satisfies the requirements of "Section 508" for software accessibility. As a result, the component can be used in US Federal Institutions and other organizations, which require software to be accessible to people with disabilities. The features listed below are essential for "Section 508" compliance:
- AccessKey - a key combination that allows the end-user to focus on the respective treeview (e.g. Alt+W).
- Arrowkey Navigation and Key Commands - allows end-users to navigate around the treeview structure using the arrow keys, as well as to use the Plus, Minus, Space, Enter, and F2 keys for additional control. Read more...
- LongDesc attribute for links, Title/Alt (ToolTip) attributes for images (needed by readers / narrators), e.g.
| |
 Copy Code |
... <Node Text="Some Text" NavigateUrl="http://somelink.com" Image="Image.Gif" ToolTip="Some ToolTip" LongDesc="Some LongDesc" ... />
... |

Telerik RadTreeView does not render any tables (<table> HTML tags) thus there's no need for extra headings / caption / summary attributes that are typically needed to make HTML tables "Section 508" compliant. |
Section 508
The USA federal mandate requires 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.
- Narrator support - Telerik RadTreeView supports the Narrator and the end-user can hear the "ToolTip" message of each "TreeNode" as he/she hovers the node with the mouse. This is helpful for people with visual imparities. <_o3a_p>
- Magnifier support - Telerik RadTreeView fully supports the Magnifier. It correctly focuses the view of Telerik RadTreeView as the user navigates through the categories. No matter how high the magnification is set, the main categories and the subcategories are proportionately increased in size for easier viewing.
- Keyboard support - Telerik RadTreeView can be navigated using only the keyboard, which is a key requirement by the Section 508 Compliance Act. You can navigate up and down the tree structure by using the Up and Down arrows respectively and expand/collapse treenodes using the Left and Right keyboard arrows (Internet Explorer only).
W3C Web Content Accessibility Guidelines 1.0
The main goal of these guidelines is to encourage developers in creating applications providing accessible contents. However, adhering to these guidelines will also make Web content more accessible to all kind of users, using different devices and interfaces: desktop browser, voice browser, mobile phone, automobile-based personal computer, etc.
In accordance with these guidelines W3C defines three levels of conformance developers may implement in order to provide some level of content compliance to their products:
- Compliance Level "A"
- Compliance Level "AA"
- Compliance Level "AAA"
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 QSF strive to obtain at least one of conformance levels listed above.
