Check Accessibility Dialog Box
The Check Accessibility dialog box lets you configure the settings for performing accessibility validation. For more information, see Accessibility Support in ASP.NET.
Accessibility tools are not available in Microsoft Visual Web Developer Express.
The accessibility validation tool checks only HTML markup. It does not check ASP.NET Web server controls, because markup is created dynamically by controls. In addition, ASP.NET 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.
To set the accessibility settings and validate a Web page
In Visual Studio, in Solution Explorer, select the name of the Web site.
In the Website menu, the Project menu, or the Tools menu, click Check Accessibility.
The Accessibility Validation dialog box is displayed.
Select the accessibility settings, and then click Validate.
The validation results are shown in the Error List window. If the Error List window is not displayed, in the View menu, click Error List.
You can also run the accessibility validation tool every time that you build a page or Web site. For more information, see Build, Web Site Property Pages Dialog Box.
