The DataGrid control that was included with the Microsoft .NET Framework 1.1 was not compliant with section 508 of the Rehabilitation Act (http://www.access-board.gov/508.htm) or with the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines (WCAG) (http://www.w3.org/TR/WCAG10/). Data tables that contain two or more rows or columns must identify row and column headers.
This design issue is being addressed in a design change.
You must render the column headers that are mentioned in the "Symptoms" section as <th>, and the columns must reference the headers.
The Section 508 hotfix introduces new properties to make the DataGrid control accessible. These properties are UseAccessibleHeader, Caption, and CaptionAlign. By default, the value of UseAccessibleHeader is false. When UseAccessibleHeader is set to true, it renders DataGrid table headers in <th> tags with a scope="col" attribute.
