    <p>I am trying to create a 404 error page and currently I have all of the following/tried all of the following to try and accomplish this. When the user types in :</p> <p><a href="http://name/something.aspx" rel="nofollow">http://name/something.aspx</a></p> <p>It works just as its supposed to. But if the user types in:</p> <p><a href="http://name/NotAFile" rel="nofollow">http://name/NotAFile</a></p> <p>with no .aspx then IIS7 takes matters into its own hands and I get the lovely error page that IIS7 comes with. The goal is that the site redirects with only a 404 status code (so not a 200, or a 302 redirect). I have tried in both the web config with:</p> <pre><code>&lt;customErrors mode="On" defaultRedirect="~/error/Default.aspx redirectMode="ResponseRewrite"&gt; &lt;error statusCode="404" redirect="~/error/NotFound.aspx" /&gt; &lt;/customErrors&gt; </code></pre> <p>This works for the url with a .aspx file extension but not for no extension. Same with this approach in the global.asax</p> <pre><code>void Application_Error(object sender, EventArgs e) { var serverError = Server.GetLastError() as HttpException; if (serverError != null) { if (serverError.GetHttpCode() == 404) { Server.ClearError(); Server.Transfer("~/error/NotFound.aspx"); } Server.Transfer("~/error/Default.aspx"); } } </code></pre> <p>The same results are present for this :( My final attempt was to apply this to the web config:</p> <pre><code>&lt;system.webServer&gt; &lt;httpErrors existingResponse="PassThrough" /&gt; &lt;/system.webServer&gt; </code></pre> <p>With this I just get a plain white screen with nothing on it... Any thoughts or comments would be greatly appreciated!! Thanks in advance!</p>

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.
