I am definitely doing something wrong and I would greatly appreciate someone pointing me in the right direction.

Many thanks in advance.

 I am trying to validate file upload along with a few other form fields.

All the form fields listed in the script below are being validate except the single file upload called BidIDFile.

Any ideas what I am doing wrong?

1.   <script type=' text/javascript' src=" http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/additional-methods.js"></script>
   script type=' text/javascript'>// <![CDATA[ $(document).ready(function () {
       // We'll use this flag so we don't have to validate fields before // the form has been submitted. var validatingForm = false;
    
   // This line before validate() is called allows // chosen menus to be validated $.validator.setDefaults({ ignore: " :hidden:not(select)" });
    
       $(' #form1').validate({ // initialize the plugin         invalidHandler: function() {
           // Now we can validate the fields onChange         validateForm = true;
       },
    
           rules: {
                      errorElement: ' div',
                       txtBidDate: " required",
                       txtDueDate: " required",
                       BidTitle: " required",
                       BidID: " required",
                       CategoryID: " required",
                       BidIDFile: " required",
                       AliasID: " required",
                       BidContact: " required",
                       ContactEmail: {
                           required: true,
                           email: true
                       },
               BidType: {
                   required: true,
               },
                        BidStatus: " required"
           },
                   messages: {
                       txtBidDate: " Please enter Issue Date",
                       txtDueDate: " Please enter Due Date",
                       BidTitle: " Please enter Project Title",
                       BidID: " Please enter ID",
                       CategoryID: " Please select a Category",
                       BidIDFile: " Please select a Bid File",
                       AliasID: " Please select Department Alias",
                       BidContact: " Please enter Bid Contact",

                       BidType: {

                       },
                       ContactEmail: " Please enter a valid email address",
                       BidStatus: " Please select Bid Status"
                   },
            });
      // Now set an onChange event for the chosen menu    $(" CategoryID").change(function(){
    
          // Check that we've tried to submit the form        if(validateForm) {
              // We tried to submit the form, re-validate on change...just to get rid of the message            $(" CategoryID").valid();
          }
   });
      $(" AliasID").change(function(){
    
          // Check that we've tried to submit the form        if(validateForm) {
              // We tried to submit the form, re-validate on change...just to get rid of the message            $(" AliasID").valid();
          }
   });
      $(" BidType").change(function(){

          }
   });
   });// ]]>
