试试这个：

Jquery的

$(document).ready(function () {

       if ($("#Select1").val() == "dayscholar") 
        {
          $("#Select2").attr('disabled','disabled');
        }
        else
        {
          $("#Select2").removeAttr('disabled');
        }


         $("#Select1").change(function () {

         if ($(this).val() == "dayscholar") 
         {

          $("#Select2").attr('disabled','disabled');
         }
             else
             {
              $("#Select2").removeAttr('disabled');
             }
         });
    });

cshtml代码：

 <tr>
                        <td class="einput">Admission Type :
                        </td>
                        <td class="einput">
                            @Html.DropDownListFor(model => model.Adm_Type_LSeq, (SelectList)ViewBag.lstAdmType, String.Empty, new { @class = "drpclass" ,@id="Select1" })
                        </td>
                        <td class="einput">Hostel Name :
                        </td>
                        <td class="einput">
                            @Html.DropDownListFor(model => model.Hostel_Seq, (SelectList)ViewBag.lstHostel, String.Empty, new { @class = "drpclass",@id="Select2" })
                        </td>
               </tr>
