仍然没有官方方法可以在 DatePicker 中选择多个日期。但是，借助 jQuery，您可以实现此功能。

HTML：

<table>
  <tr>
    <td style="vertical-align: initial; padding-right: 100px;">
      <input id="picker" />
    </td>
    <td>
      <div id="calendar"></div>
    </td>
  </tr>
</table>

CSS：

.k-state-selected {
  background-color: transparent;
  border-color: transparent;
  background-image: none;
}

td.k-state-focused.k-state-selected {
  box-shadow: none;
}

.k-state-selected > .k-link {
  color: black;
}

.selected {
  background-color: #F35800;
  border-color: #F85A00;
  background-image: none, linear-gradient(to bottom, rgba(255, 255, 255, 0.2) 0px, rgba(255, 255, 255, 0) 100%);
}

.selected > .k-link {
  color: #FFF;
}

JS：

$(function() {
  var day = 86400000;
  var today = new Date();
  //time is set to midnight for correct comparison with values from calendar
  today.setHours(0, 0, 0, 0);

  //data source
  var selectedDates = [
    today.getTime() - day,
    today.getTime(),
    today.getTime() + day
  ];

  //DatePicker with multiselection
  initPicker($('#picker').kendoDatePicker(), selectedDates);

  //Calendar with multiselection
  //initCalendar($("#calendar").kendoCalendar(), selectedDates.slice());
});

function initPicker(picker, selectedDates) {
  var isInit = false;
  var kendoPicker = picker.data('kendoDatePicker');

  kendoPicker.bind('open', function() {
    if (!isInit) {
      //assuming that corresponding calendar widget has id 'picker_dateview'
      var calendar = $('#' + picker.attr('id') + '_dateview > .k-calendar');

      initCalendar(calendar, selectedDates, function() {
        updatePicker(picker, selectedDates);
      });

      isInit = true;
    }
  });

  picker.on('input change blur', function() {
    updatePicker(picker, selectedDates);
  });

  updatePicker(picker, selectedDates);
}

function initCalendar(calendar, selectedDates, onUpdate) {
  var kendoCalendar = calendar.data('kendoCalendar');

  kendoCalendar.bind('navigate', function() {
    setTimeout(function() {
      updateCalendar(calendar, selectedDates);
    }, 0);
  });

  updateCalendar(calendar, selectedDates);

  calendar.on('click', function(event) {
    var cell = $(event.target).closest('td');
    var isClickedOnDayCell = cell.length !== 0 && isDayCell(cell);

    if (isClickedOnDayCell) {
      var date = dateFromCell(cell).getTime();
      var isDateAlreadySelected = selectedDates.some(function(selected) {
        return selected === date;
      });

      if (isDateAlreadySelected) {
        selectedDates.splice(selectedDates.indexOf(date), 1);

      } else {
        selectedDates.push(date);
      }

      updateCell(cell, selectedDates);

      if (onUpdate !== undefined) {
        onUpdate();
      }
    }
  });
}

function updatePicker(picker, selectedDates) {
  var datesString = selectedDates.sort().reduce(function(acc, selected, index) {
    var date = new Date(selected);
    var formattedDate = (date.getMonth() + 1) + '/' + date.getDate() + '/' + date.getFullYear();

    return acc + formattedDate + (index === (selectedDates.length - 1) ? '' : ', ');
  }, '');

  picker.val(datesString);
}

function updateCalendar(calendar, selectedDates) {
  calendar.find('td > a').parent().each(function(i, item) {
    var cell = $(item);

    if (isDayCell(cell)) {
      updateCell(cell, selectedDates);
    }
  });
}

function updateCell(cell, selectedDates) {
  var isCellSelected = selectedDates.some(function(selected) {
    return selected === dateFromCell(cell).getTime();
  });

  if (isCellSelected) {
    cell.addClass('selected');

  } else {
    cell.removeClass('selected');
  }
}

function isDayCell(cell) {
  return /^\d{1,2}$/.test(cell.find('a').text());
}

function dateFromCell(cell) {
  return new Date(convertDataValue(cell.find('a').attr('data-value')));
}

//convert from 'YYYY/MM/DD', where MM = 0..11
function convertDataValue(date) {
  var regex = /\/(\d+)\//;
  var month = +date.match(regex)[1] + 1;

  return date.replace(regex, '/' + month + '/');
}

我不太确定，但据我所知，目前不支持多选行为，因为日期选择器日历只能有一个日期作为选定值。但如果你真的需要这个选项，你可以自定义它

http://demos.telerik.com/kendo-ui/datepicker/template

并在范围内添加一个通用图像（如下划线）并使用循环给出日期。 在日历中，您可以更改其背景颜色。

这是您可以尝试的示例代码：
