i work on Windows form, i have this data that the user fill the textbox, after that i need to save the data to my context ( database ), this is my code to insert data to my data base , but i have data ( numbers and some string ) the user will chose from ComboBox. i need to get this data and save it to a list of object , this is the code :

 public class Groups
    {
        [Key]
        public string GroupsID { set; get; }

        public string NameOfGroup { set; get; }
        ***public virtual List<ScoutData> Members { set; get; }***
    }

The context:

  public class ScoutContext : DbContext
    {
        public ScoutContext()
            : base("Scout")
        {
        //    if (!Database.Exists("ScoutData"))
        //        Database.SetInitializer(new DropCreateDatabaseAlways<ScoutContext>());
        }
        public DbSet<ScoutData> ScoutDatas { set; get; }
        public DbSet<Groups> GroupesScout { set; get; } 
    }

i need to get this data from the combobox to Members list and save it to a list of object (Members)

What is the GUI technology you use - WinForms, WPF, WebForms...? What is contained in that ComboBox - does it have some DataSource or has it been filled directly? — Eugene Podskal, Jan 08 '17 at 18:34
see http://stackoverflow.com/questions/6901070/getting-selected-value-of-a-combobox — Shane Sepac, Jan 08 '17 at 18:35
That [should have been mentioned](http://meta.stackoverflow.com/questions/260648/stack-overflow-question-checklist) in the question initially. And what that data is (some special class, or `Groups`)? Add how exactly do you fill it. — Eugene Podskal, Jan 08 '17 at 18:40

It depends on what you have in the combobox.

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    var combo = sender as ComboBox;

    // If combobox has ScoutData then do this
    var item = combo.SelectedItem as ScoutData;

    // If combobox has something else then do this
    var item2 = combo.SelectedItem as SomeThingElse;
    var newScout = new ScoutData { FName = item2.FName /*, etc, etc */  };

    // Then add it to your list
}

I update some information, sorry but i'm new here :( – Piero Chankji Jan 08 '17 at 20:33 — Piero Chankji, Jan 08 '17 at 20:33
