Change enum value in Database using EF - asp.net

Question

sorry for my english, hope you're doing okay , i'm stuck in a list situation using MVC, i have a class named student
public class student
{
[Key]
public int student_Id { get; set; }
public DateTime startdate { get; set; }
public DateTime enddate { get; set; }
public statut studentstatut { get; set; }
}
public enum statut
{
Garden,
Elementary,
College,
}
i want to edit the class student , i can edit the Id , both dates , but when i want to edit the enum statut it won't , it stays in Garden and when i check my database in studentstatut it shows 0, i don't know how to make them dynamic so that i can see the studentstatut in the database and edit the statut (for exemple edited from garden to elementary ) , can anyone help please ?

First, I would verify that you are getting the correct data back from your HttpPost Edit method. If you're able to edit and save the other fields It's possible that your client-side control is not correctly setting the correct field for your student object. Put a breakpoing in that method to verify that the studentstatut field is correctly being set.
If it is, and it is somehow not saving to your database context, you can try manually setting the field rather than using EntityState.Modified. You can do that with something along the lines of:
db.Entry(student).studentstatut = student.stdentstatut;
Though usually EntityState.Modified should do the trick.
