Window / Accessibility


  • The interface of RadWindow for ASP.NET AJAX is level A accessible (in compliance with the W3C Web Accessibility Guidelines 2.0) as well as Section 508 compliant.

    RadWindow passes the check of the WAVE automated content compliance tool for Section 508 and WCAG 2.0 - Compliance Level A.

    Keyboard support

    The RadWindow supports now keyboard shortcuts for its commands. Shortcuts can be used as an accessibility feature, or to make the work of the user more convenient. Shortcuts can be used to switch between active windows, to maximize or close the current active window, and other tasks.

    This test demo has the following shortcuts specififed for demonstration purposes:
    RadWindowManager:
    RestoreAll Shortcut - Alt+F3
    Tile Shortcut - Alt+F6
    CloseAll Shortcut - Esc

    RadWindow with NavigateUrl="http://www.telerik.com":
    Maximize Shortcut - Ctrl+F2
    Restore Shortcut - Ctrl+F3

    RadWindow with ContentTemplate set:
    Maximize Shortcut - Ctrl+F6
    Minimize Shortcut - Ctrl+F7

    Shortcuts can be specified in the markup as shown in the demo or on the srever e.g as shown below:

    RadWindow1.Shortcuts.Add("Close", "Esc");
    or
    RadWindow1.Shortcuts.Add(new Telerik.Web.UI.WindowShortcut("Close", "Esc");

    The command names are not case-sensitive and if such a command exists, it will be fired for the currently active RadWindow or for all windows in a manager if this the case.
