  • Updating Data with LINQ to SQL and GridViews when using a View

    Look! It's a post that isn't about SharePoint! Today, I want to talk about some of the issues I have run into when trying to update data using a GridView when bound to a LinqDataSource.

  • Returning a single object with LINQ to SQL

  • LINQ to SQL Under the Covers

    With the release of the 3.5 extensions to the framework, there has been a lot of talk about LINQ and with it LINQ to SQL.
