If you were to do this using ASP.NET 3.5 Sp1 WebForms you would have to create a seperate ImageHTTPHandler that implements IHttpHandler to handle the response. Essentially all you would have to do is put the code that is currently in the GetHttpHandler method into your ImageHttpHandler's ProcessRequest method. I also would move the GetContentType method into the ImageHTTPHandler class. Also add a variable to hold the name of the file. Then your ImageRouteHanlder class looks like: <pre><code>public class ImageRouteHandler:IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { string filename = requestContext.RouteData.Values["filename"] as string; return new ImageHttpHandler(filename); } } </code></pre> and you ImageHttpHandler class would look like: <pre><code> public class ImageHttpHandler:IHttpHandler { private string _fileName; public ImageHttpHandler(string filename) { _fileName = filename; } #region IHttpHandler Members public bool IsReusable { get { throw new NotImplementedException(); } } public void ProcessRequest(HttpContext context) { if (string.IsNullOrEmpty(_fileName)) { context.Response.Clear(); context.Response.StatusCode = 404; context.Response.End(); } else { context.Response.Clear(); context.Response.ContentType = GetContentType(context.Request.Url.ToString()); // find physical path to image here. string filepath = context.Server.MapPath("~/images/" + _fileName); context.Response.WriteFile(filepath); context.Response.End(); } } private static string GetContentType(String path) { switch (Path.GetExtension(path)) { case ".bmp": return "Image/bmp"; case ".gif": return "Image/gif"; case ".jpg": return "Image/jpeg"; case ".png": return "Image/png"; default: break; } return ""; } #endregion } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
