Finally I am out of the terrible error-jungle that I was in (note to self, do NOT use SQLExpress for local development!). I now have another issue:
I am working on a custom module for sitefinity and I am following Gabe Sumner's webinar on the subject. I just created my tables and my LINQ to SQL data access layer, and have bound it to a RadGrid. I enabled the 'add new record feature', as well as enabled delete/insert/update on the LinqDataSource:
When I go to add or modify a record, it allows me to do so but the changes are not reflected on the page, refreshing the control doesn't help. Viewing the table inside of Microsoft SQL Server Management Studio shows that no updates took place either.
So there must be something that I am missing...a setting or switch or something that I overlooked during the webinar that is preventing my RadGrid from adding/updating/modifying my records.
Thanks in advanced!
