Question

I am really confused about why an update is not taking place. This is very simple:

    int goodID = 100;      DataContext db = new DataContext();      Schedule schedule = db.Schedules.Single(s => s.ID == goodID);      // this wont persist - WHY NOT?!     schedule.Email = txtEmail.Text;      // this does persist     schedule.NumberCourses = 5;      db.SubmitChanges(); 

I can’t understand why the field, Email, isn’t getting the value from the textbox. What can I check?

EDIT

I have set a breakpoint and checked the value after assignment. It assigns the textbox value but still no update.

I am an idiot. It’s fixed. Votes for everyone. Instead of checking in the database, like a normal person would, I was just looking on the webform after refreshing the page. I wasn’t initializing the textbox with the value from the db. So the update was happening. See? I told you I was an idiot.
