While working on a nested datagrid, I had the problem that I could not edit the nested datagrid. When I pressed the edit button in the nested datagrid nothing happend. After searching on google I found the following KB article which resolved this problem.
BUG: When you click Edit for the child DataGrid control, nothing happens in Visual Studio .NET 2003Sonu
I wrote a reblogger for TopXML which aggregates XML blogs and news. You can check it out here. It has already 127 xml news. Here is the explaination from TopXML:
"Reblogger is a free aggregator service provided by TopXML. We collect XML blog items twice a day from around the web, so that you can view all the most interesting and most useful news right here in our reblogger. Enjoy"
TopXML contracted me to write this software because of previous my experience in other projects Over the next two weeks I built this system. I am very proud of the Reblogger, because I actually like using it - I need a good service as a source of news about the happenings of the XML world. If you require something built for your website, I am available for ASP/ASPX/.NET contract programming. Please do not hesitate to contact me.
Update: RSS for the Reblogger is comming soon. Get the RSS feed here.
