THyperLink class

THyperLink displays a hyperlink on a page. The hyperlink URL is specified via the NavigateUrl property, and link text is via the Text property. It is also possible to display an image by setting the ImageUrl property. In this case, Text is displayed as the alternate text of the image. The link target is specified via the Target property. If both ImageUrl and Text are empty, the content enclosed within the control tag will be rendered.
