Custom Insert/Update on LinqToSql and ASP.NET Dynamic Data

ASP.NET Dynamic Data brings major usability and RAD development changes to the existing ASP.NET data controls. RAD development is significantly increased by the use of a rich scaffolding framework.

If you want to create a custom insert or update for ASP.NET Dynamic data and LinqToSQL then you will have to perform the following steps:
1) Create a partial class for the entity you want to make the insert/update custom. For example if you had a table name employees then your code would look like this:

[ScaffoldTable(true)]
public partial class Employees
{
}
