title: Multiple selection of ListBox is not working in asp.net mvc4
body: <p>I have bound listbox data from entity framework. I have selected multiple values in that listbox. But, the values are not fired. The count of the property is 0 only. I am using the code below:      </p>
  
  <pre><code>public class Sample1  
  {  
  [Key]  
  public int SampleId{ get; set; }  
  public string SampleDesc{ get; set; }  
  }
  public class ExpModel  
  {  
  public List&lt;Sample1&gt; Sample{ get; set; }  
  }
  public ActionResult Index()  
  {       
  ViewData["SampleList"] = new List&lt;Sample1&gt;(entity.samp);  
  return View();  
  } 
  @Html.ListBoxFor(model =&gt; model.Sample, new  SelectList(((List&lt;Details.Models.Sample1&gt;)ViewData["SampleList"]), "SampleId", "SampleDesc")) 
  </code></pre>
