Sorting by date

[Lee]

I would like to sort my datasource by date.  However, whenever I change the field type from "string" to "date" I get "null" in place of the dates.  The format of the dates is:  dd-mm-yy hh:mm

 Can anyone see what I am doing wrong?

var ticketDataSource = new kendo.data.DataSource({

      transport: {

          read: "/support/data",

          dataType: "json",

          create: {

              url:  function() {

                  if (support_create_type == 'new'){

                      var url = "/support/newticketpost/";

                  } else if (support_create_type == 'reply'){

                    var url = "/support/reply/" + support_id + "/";

                  }                          

                   

                  return url;

              },

              type: "POST",

              dataType: "json"                   

          },

          update: {

              url:  function() {

                  if (support_update_type == 'markasread'){

                    var url = "/support/markasread/" + support_id + "/";

                  } else if (support_update_type == 'close'){

                     var url = "/support/close/" + support_id + "/" + support_ticket_closed; 

                  }

                  return url;

              },

              type: "POST",

              dataType: "json"

          },               

      },

     error: function(e) {

        alert(e.responseText);

     },

     sort: { field: "DateCreated", dir: "asc" },

   

      schema: {

        model: {

            id: "ThreadID",

            fields: {

                DateCreated:  { type: "date" },

                Subject:  { type: "string" },

                Closed:  { type: "string" }                    

               }

           }

       }

   });

Many thanks,

In answer to this, I needed to define a custom parser and create the dates on the client.

schema: {
    model: {
        id: "foo",
        fields: {
            foo: {type: "number"},
            bar: {type: "date", parse: parseDate}
        }
    }
}

function parseDate(rawDate) {
    //create a valid JavaScript date object from the rawDate string
    return date;
}
