You can display content defined for a Web page or within a CDATA tag on a work item form by using the WebpageControlOptions element. You can include either the Link or the Content child elements to specify either a URL or HTML for the content to appear in the form.

To add elements to a form, you modify a work item type. See Modify or add a custom work item type.

The WebpageControlOptions element is a child element of the CONTROL element.

Remarks

The Link and Content elements are mutually exclusive.

The AllowScript and ReloadOnParamChange attributes are not allowed when you use the Content element.

When the Web page control is configured to display raw HTML, all scripting is disabled. Any hyperlinks in the content that are clicked are opened in the Visual Studio Web browser if the work item form is shown in Visual Studio or in Internet Explorer.
Several toolbar buttons are added to the work item form for a tab that contains WebpageControl. These options include the following functions:

  • Back and forward navigation
  • Stop content loading and refresh content
  • Return to content home page
  • Open the content in a new window or in an external browser

In addition, if the Web page to be loaded contains untrusted content, then the icon is blocked and the blocked icon appears.

The WebpageControlOptions element is only recognized by clients that are running the latest version of Team Explorer. For previous versions, a red area is displayed and a message appears indicating that the control could not be found. For more information, see Provide help text, hyperlinks, or web content.
