Kendo UI - Drag and Drop functionality not working as expected within a Scheduler component

[Fernando]

Context

We're using Scheduler component and a custom list of items. We're also using the Draggable component to let the items to be dropped into the Scheduler component. You can find the layout of the implementation in the attachment.

The configuration of the items is the following:

$(element)
  .find(`.${NS}customer-list__draggable`)
  .kendoDraggable({
    hint: () => {
      var draggableElem = $(`
      <span class="ui-draggable ${NS}customer-list__dragging">
        ${scope.customer.name} <br>
      </span>
      `);
      draggableElem.css({
        borderLeft: `3px solid ${scope.customer.displayColor}`
      });
      return draggableElem;
    },
    dragstart: event => {
      // prevent dragging on agenda view
      if ($rootScope.scheduler.viewName() === "agenda") {
        event.preventDefault();
      }
    },
    autoScroll: false,
    containment: "window",
    cursorOffset: { right: 0, top: 0, left: 0, bottom: 0 },
    distance: 50,
    group: "schedulerCustomerGroup"
  });

The configuration of the Drop are is the following:

scheduler.view().table.kendoDropTargetArea({
  group: 'schedulerCustomerGroup',
  filter: '.k-scheduler-table td, .k-scheduler-header-all-day td, .k-event',
  dragenter: (e) => {
    var offset = $(e.dropTarget).offset(),
          slot = scheduler.slotByPosition(offset.left, offset.top);

    $(slot.element).css('background', '#bce8f1');
  },
  dragleave: (e) => {
    var offset = $(e.dropTarget).offset(),
          slot = scheduler.slotByPosition(offset.left, offset.top);

    $(slot.element).css('background', '');
  },
  drop: (event) => {
    var offset = $(event.dropTarget).offset(),
        slot = scheduler.slotByPosition(offset.left, offset.top),
        dragElem = event.draggable.element[0],
        customer = _.find($rootScope.customers, {id: $(dragElem).data('customerId')});

    $(slot.element).css('background', '');

    scheduler.addEvent({
      title: customer.name,
      start: slot.startDate,
      end: slot.endDate,
      description: '',
      customerId: customer.id,
      streetAddr: customer.streetAddr,
      city: customer.city,
      state: customer.state,
      country: customer.country,
      zip: customer.zip,
      phone: customer.phone,
      lat: customer.lat,
      long: customer.long,
      accountId: customer.accountId,
      contactId: customer.d_tx_uid,
      isAllDay: slot.isDaySlot,
    });
  }
});

You can notice the group setting is the same in both configurations: schedulerCustomerGroup.

The filter configured in the kendoDropTargetArea is the following:

• .k-scheduler-table td
• .k-scheduler-header-all-day td
• .k-event

As you can see, the filter include all the cells in the Scheduler component.

Problem

The problem I'm having is when using the Work Week, and resizing the browser to an specific dimension, some cells are not being detected as drop area.

As you can see, I cannot drop the item in Wed 2/21.

A workaround is to resize the browser, but that's not a final solution I'm expecting to have.

Hi, Fernando,

The overall logic seems correct, but I am having some troubles with the reproduction of the issue.

Would it be possible for you to share a small Dojo sample where the problem can be observed? I'll try to debug it and find a solution.

Best Regards,

Georgi
