Here is a freebee for the DNN developers out there. The sitemap.aspx file included with DNN 05.00.00 didn't work with google. It would return a invalid format error so I set out to fix that and also add the ability to render blog posts into the sitemap.

It is a pretty simple task to modify the sitemap.aspx file to render blog posts so I increased the degree of difficulty by converting the entire control to C#. (I am not a big VB fan so I convert when reworking a control)

The markup code just contains the header:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SiteMap.aspx.cs" Inherits="Default2" %>

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SiteMap.aspx.cs" Inherits="Default2" %>

And here is the codebehind file…
