  <p>This is my view code:</p>
  
  <pre><code>        &lt;div&gt; @Html.LabelFor(m =&gt;m.CustID)
      @Html.DropDownList("CustID", "---Select---")

  <p>I am getting this error on <code>DropDownList</code>: <code>The ViewData item that has the key 'CustID' is of type 'System.Int32' but must be of type 'IEnumerable&lt;SelectListItem&gt;'</code>. Can anyone help me?</p>
