This article describes an update that fixes two Report Viewer functionality issues that occur after you install Microsoft Visual Studio 2010 Service Pack 1 (SP1). These issues also occur when you use the Report Viewer control in Microsoft Report Viewer 2010 SP1 Redistributable Package.

Issues fixed by this update

Issue 1

When you render a report by using a Microsoft Report Viewer 2010 control, the HTML format of the report is not compliant with the following standard in the "Web-based Intranet and Internet Information and Applications" section (1194.22) of the Electronic and Information Technology Accessibility Standards (Section 508) document:

(a) A text equivalent for every non-text element shall be provided (For example, "alt", "longdesc" or in element content).Specifically, when you view the HTML source of a webpage that contains Report Viewer 2010 controls, you experience the following:

  • The "<label>" tag and its associated for attribute are not used to point to related input parameters.

  • The "Loading" image element does not contain the alt attribute.

Issue 2

Assume that you use the Windows Forms control of Report Viewer 2010 in a Microsoft Visual C++ MFC application. When you set the ShowContextMenu property to false to hide the shortcut menu, the setting is ignored. Therefore, Report Viewer does not hide the shortcut menu at run time.
