Kendo ui 如何验证剑道日期时间选择器

我正在使用剑道日期时间选择器。单击“提交”按钮时出现问题。 1） 必须选择日期和起始日期。如何获得弹出窗口，该弹出窗口应验证日期和时间，并且不允许使用字母表

 $("#startdatetimepicker").kendoDateTimePicker({
 showSecond: true,
    dateFormat: "dd-mm-yy",
      timeFormat: "HH:mm:ss",
      format: "dd-MM-yy HH:mm:ss",

      mindate: getFormattedDate(new Date())

  }).data("kendoDateTimePicker");

$("#startdatetimepic").attr("readonly", "readonly");
function getFormattedDate(date) {
       alert("")
    var day = date.getDate();
    var month = date.getMonth() + 1;
    var year = date.getFullYear().toString().slice(2);
    return day + '-' + month + '-' + year;


}
 $("#enddatetimepicker").kendoDateTimePicker({

      showSecond: true,
      dateFormat: "dd-mm-yy",
      timeFormat: "HH:mm:ss",
      format: "dd-MM-yy HH:mm:ss"
  }).data("kendoDateTimePicker");


  var result = $("#grid").kendoGrid({
      filterable: true,


      columns: [{
          field: "FirstName",
          title: "First Name"
      }, {
          field: "LastName",
          title: "Last Name"
      }, {
          field: "dob",
          title: "DOB",
          format: "{0:dd-MM-yy HH:mm:ss}"
      }],
      dataSource: {
          data: [ {
              FirstName: "Joe",
              LastName: "Smith",
              dob: "2013-02-01 19:54:13"
          }, {
              FirstName: "Jane",
              LastName: "Smith",
              dob: "2013-02-02 20:55:14"
          }, {
              FirstName: "Jane",
              LastName: "Smith",
              dob: "2013-02-03 21:56:15"
          },
         {
              FirstName: "Jane",
              LastName: "Smith",
              dob: "2013-03-4 20:56:14"
          }],
          schema: {


              data: function (data) {
                  $.each(data, function (i, val) {
                      val.dob = kendo.parseDate(val.dob, "yyyy-MM-dd HH:mm:ss");
                  });
                  return data;
              }
          }

      }
  }).data("kendoGrid");


  $("#filter").on("click", function () {
      var mindate = $('#startdatetimepicker').data("kendoDateTimePicker").value();
      var maxdate = $('#enddatetimepicker').data("kendoDateTimePicker").value();

      var condition = {
          logic: "and",
          filters: []
      };
      if (mindate !== null) {
          condition.filters.push({
              field: "dob",
              operator: "ge",
              value: mindate
          });
      }
      if (maxdate !== null) {
          condition.filters.push({
              field: "dob",
              operator: "le",
              value: maxdate
          });
      }
      result.dataSource.filter(condition);


  });

在递增值时，格式应禁止使用字母字符，可实现类似于：

function incrementDay(increment) {
            var datePicker = $("#DayPager").data("kendoDatePicker");
            var val = datePicker.value();
            var newDate = new Date(val.getFullYear(), val.getMonth(), val.getDate() + increment);           
            datePicker.value(newDate);           
        }
