Accessibility, Web Site Property Pages Dialog Box 

The Accessibility dialog box allows you to configure the settings that are in effect if you choose to perform accessibility validation while building the page or Web site, as set in the Build, Web Site Property Pages Dialog Box. For more information, see ASP.NET Accessibility (Visual Studio).


Accessibility tools are not available in Microsoft Visual Web Developer Express Edition.

The accessibility validation tool checks only HTML markup. It does not check ASP.NET Web server controls, because markup is created dynamically by controls (therefore, the tool cannot check the validity of the markup). Also, controls do not have metadata for ASP.NET to create an accessibility schema. It is recommended that you test the output of your pages in addition to using design-time accessibility validation tools.

The results of an accessibility validation check are displayed in the Error List Window. If the Error List window is not visible, in the View menu, click Error List.

To access this dialog box
  1. In Microsoft Visual Web Developer, in the Solution Explorer pane, click your Web site project name.

  2. Click View and then click Property Pages.

    Alternatively, you can right-click your Web site project name in Solution Explorer and click Property Pages.

    The Property Pages window appears.

  3. Click the Accessiblity node.
