Hyperlink implements the NavigateUri property that you set with the Uri of the content that should be navigated to when the Hyperlink is clicked. Hyperlink navigation can only occur, however, if either the direct or indirect parent of a Hyperlink is a navigation host, including NavigationWindow, Frame, or any browser that can host XBAPs (which includes Internet Explorer 7, Microsoft Internet Explorer 6, and Firefox 2.0+). For more information, see the Navigation Hosts topic in Navigation Overview.
Content Model: Hyperlink enforces a strong content model for child content. See TextElement Content Model Overview for more information about the Hyperlink content model.
