ASP.Net HtmlControls and WebConstrols support ~ as the application base path

Note that ASP.Net’s internal controls , such as HtmlControls and WebControls, all support the ~ as the application base path designator whereever you can provide a link. For example in the Image Control you can say:

MyImage.ImageUrl = "~/images/stop.gif";

which will always load the image out of the application’s images directory regardless where the current page lives.
