Question

I am using LINQ to SQL to interact with my database and I am trying to do the following to update a single row in the database:

DataClassesDataContext dataContext = new DataClassesDataContext();

TableName aRow = (from rows in dataContext.TableNames where rows.x == y select rows).Single();
aRow.attribute = "something";

dataContext.SubmitChanges();

shouldn’t this update the database with the change I made to the row?
or is there something I’m missing?

thanks for any help

A couple of things to check:

1. Is your code snippet using the same DataContext, meaning it’s not cut and pasted from different methods where you’re instantiating new DataContext instances?
2. Is your DataContext.ObjectTrackingEnabled property set to true? It should be by default, but if it’s false then your DataContext won’t be able to perform the update.
