Details view doesn't work mvc 5

I have a MVC 5 application. I follow up this tutorial Getting Started with ASP.NET MVC 5

Altough when I click Details, Edit or Delete I get HTTP Error 400.0 - Bad Request.

My Index view

@foreach (var item in Model)
    {
 <div class="city">
 <h2>@Html.DisplayFor(modelItem => item.announce_PublishDate)</h2>
 <p>@Truncate(item.announce_Description, 90)</p>
 <p>@Html.ActionLink("more", "Details", new { id = item.announce_ID }) </p></div>}

My Details view

<div>
<h4>prokirikseis</h4>
<hr />
<dl class="dl-horizontal">
    <dd>
        @Html.DisplayFor(model => model.announce_ID)
    </dd>
    <dd>
        @Html.DisplayFor(model => model.announce_Description)
    </dd>
    <dd>
        @Html.DisplayFor(model => model.announce_PublishDate)
    </dd>

    </dl>
    </div>
      <p>
@Html.ActionLink("Edit", "Edit", new { id = Model.announce_ID }) |
@Html.ActionLink("Back to List", "Index")</p>

the controller

public ActionResult Details(int? id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        announce announce= db.announce.Find(id);
        if (announce == null)
        {
            return HttpNotFound();
        }
        return View(announce);
    }

the model 

public class announcements 
{
    [Key]
    public String announce_ID { get; set; }

    [Display(Name = "Date")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
    public Nullable<System.DateTime> announce_PublishDate { get; set; }

    [Display(Name = "Title")]
    public String announce_Description { get; set; }
}

What I am doing wrong? I notice that it brings the right ID in the url. http://localhost:zzzzz/ltest/Details/01_2.2 but it does't bring the content. thank you

Your action methods are accepting a parameter which is typeof int but the key in class announcements is string, not int. (and the url in your question is passing a value of 01_2.2 to the Details() method so id is null).

Change your methods to

public ActionResult Details(string id)

although I recommend you actually change the key to be an auto incremented int
