Question

I have this code:

protected void Page_Load(object sender, EventArgs e)
{
    if (Page.IsPostBack)
    {
        using (mesteriEntities myEntities = new mesteriEntities())
        {
            var usern = Session["New"];

            var UserID = (from Users in myEntities.Users
                          where Users.UserName == usern
                          select Users.UserID).SingleOrDefault();

            var cati = Convert.ToInt32(DropDownList1.SelectedValue);

            Job newJob = new Job();
            newJob.categID = cati;
            newJob.userID = UserID;
            myEntities.AddToJobs(newJob);
        }
    }
}

When I select a combo it should add the value of combo and the userID in the Jobs table both INT values.
The variables “cati” and “userid” have values.

I don’t know what I should change in order to make the insert work.

Answer 1

Adding myEntities.SaveChanges() after your myEntities.AddToJobs(newJob) call should work.
Here’s the relevant documentation.
