Hi guys, I´m new to ASP.NET Core and EF Core and I have the following problem: I have two related objects, Goals and Months, Goals got the foreign key of Months, and when I try to save the data of goals I got a foreign key error because the value of MonthId is 0, but when I create the select in the HTML I got correct code value. Description of the error: SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint FK_Goals_MonthId;. The conflict occurred in database Portal_RNT, table dbo.Months , column MonthId;. The statement has been terminated. Here is the code: HTML

@model ProjectName.Models.Goals

<form asp-controller="Goals" asp-action="Create">
Other form elements

  <select name="months" asp-for="MonthId" class="form-control" asp-items="ViewBag.Months">

  </select>

  <input type="submit" value="Save" class="btn btn-primary" />

</form>

Goals Model

public class Goals
{
[Display(Name = "Code")]
public Int32 GoalId { get; set; }

    public String GoalName{ get; set; }
    public Months Month{ get; set; }
    public Int32 MonthId{ get; set; }
    ....
    Other properties

}

Month Model

public class Months
{
    \[Key\]
    \[Display(Name = "Code")\]
    public Int32 MonthId { get; set; }
    \[Display(Name = "Designation")\]
    public String Designation{ get; set; }
}

Goals Controller

public IActionResult Create(Goals goal)
{
if (ModelState.IsValid)
{
_context.Goals.Add(goal);
_context.SaveChanges();
}
return View("~/../Create.cshtml");
}

Best Regards

hi, I'm trying to get multiple values that was selected in a dropdown list, the problem is that it's only returning one value, if I select two or more values only give me one, here's the code:

List dep = new List();
foreach (ListItem item in sltnamedep.Items)
{

        if (item.Selected)
        {


            
            dep.Add(item.Text);


        }

    }
    for (int i = 0; i < dep.Count; i++)
        Response.Write(dep\[i\]);
