Kendo Grid列计算

Question

我的ASP.NET MVC项目中有一个Kendo UI AJAX网格，我想计算总检查列数。我有5个星期一到星期五（AM）列，5个星期一到星期五（PM）列，以及两个总列TotalAM和TotalPM。当用户单击复选框时，我需要计算TotalAM和TotalPM。

例如，如果选中星期一上午和星期二上午，则TotalAM应为2.同样，如果未选中PM列，则TotalPM应为0.

你能告诉我如何实现这个吗？

<%: Html.Kendo().Grid<SSTS.Models.ServiceUseViewModel>()
      .Name("grid")
      .Columns(columns =>
      {
          columns.Bound(student => student.StudentNumber).Width(150);
          columns.Bound(student => student.GivenName).Width(150);
          columns.Bound(student => student.FirstDateOfTravel).Width(150);
          columns.Bound(student => student.MondayAM).Width(150);
          columns.Bound(student => student.MondayPM).Width(150);
          columns.Bound(student => student.TuesdayAM).Width(150);
          columns.Bound(student => student.TuesdayPM).Width(150);
          columns.Bound(student => student.WednesdayAM).Width(150);
          columns.Bound(student => student.WednesdayPm).Width(150);
          columns.Bound(student => student.ThursdayAM).Width(150);
          columns.Bound(student => student.ThursdayPM).Width(150);
          columns.Bound(student => student.FridayAM).Width(150);
          columns.Bound(student => student.FridayPM).Width(150);
          columns.Bound(student => student.TotalDaysAM).Width(150);
          columns.Bound(student => student.TotalDaysPM)
                 .Width(150).ClientTemplate("#=calculateField(data)#");
          columns.Bound(student => student.IsMoreThanOnceService).Width(150);  

          columns.Command(commands =>
          {
              commands.Edit(); // The "edit" command will edit and update data items
              commands.Destroy(); // The "destroy" command removes data items
          }).Title("Commands").Width(150);
      })
      .ToolBar(toolbar => toolbar.Create()) // The "create" command adds new data items
      .Editable(editable => editable.Mode(GridEditMode.InLine)) // Use inline editing mode
      .DataSource(dataSource =>
          dataSource.Ajax()
            .Model(model =>
            {
                model.Id(student => student.StudentNumber); // Specify the property which is the unique identifier of the model
            })
            .Create(create => create.Action("serviceUse_Create", "ServiceUse")) // Action invoked when the user saves a new data item
            .Read(read => read.Action("serviceUse_Read", "ServiceUse"))  // Action invoked when the grid needs data
            .Update(update => update.Action("serviceUse_Update", "ServiceUse"))  // Action invoked when the user saves an updated data item
            .Destroy(destroy => destroy.Action("serviceUse_Destroy", "ServiceUse")) // Action invoked when the user removes a data item
      )
     .Pageable().Scrollable()
