resolveurl

Try to get the page from the handler and use ResolveUrl, or create a Control object… (HttpContext.Current.Handler as Page).ResolveUrl(“~/virtualpath”); Or use VirtualPathUtility.ToAppRelative(string) or VirtualPathUtility.ToAbsolute(string) For example: System.Web.VirtualPathUtility.ToAbsolute(“~/Styles/Contoso.xslt”); returns /WebSite/Styles/Contoso.xslt
