Describe the bug
When there is an event that lasts multiple days, but is not an all-day event the title and the up arrow overlap, thus it makes the reading of the title harder.

To reproduce
Open the Dojo - https://dojo.telerik.com/@NeliK/IruYeGEc

Expected behavior
The arrow and the title should be rendered with some margin

Bug report

If a Scheduler event's start time is set differently than :00 or :30, the event will be dropped in an incorrect slot when snap is enabled. The start time in the hint is also incorrect.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/oSaQUCOp/13
2. Drag the event to 2:00 AM and drop it. Notice that the start time in the hint is also incorrect when the event is over the 2:00 AM slot.
3. Drop the event

Current behavior

The event will be placed at 2:19 AM instead of at 2:00 AM

Expected/desired behavior

The event should be placed at the dropped slot.

Environment

• Kendo UI version: 2024.1.319
• Browser: [all]

Bug report

When a recurring event is created in a Scheduler and the id is not set to the event, then if the event is deleted an error is thrown in the console.

Reproduction of the problem

1. Open the Dojo example.
2. Create a new recurring event
3. Remove the event:
   3.1. Select the 'Delete current occurrence' option
   3.2. Select the 'Delete the series' option

Current behavior

3.1. 'kendo.all.js:311085 Uncaught TypeError: Cannot read properties of undefined (reading 'startTimezone')' is thrown
3.2. 'Uncaught TypeError: Cannot read properties of undefined (reading recurrence exception)' is thrown in the console

Expected/desired behavior

There should be no errors in the console although the deleted event is without id being set. There could be some more descriptive message.

Environment

• Kendo UI version: 2022.2.802
• Browser: [all ]

Bug report

If the snap option is set at runtime the drag hint of the events starts having wrong height.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/ilaziJEr
2. Try to disable and enable the Switch at the top ( you may need to disable and enable multiple times)
3. Drag the event

Current behavior

After changing the snap option at runtime as a result the drag hint height is correct when the snap is set to false, but it has wrong height when the snap is enabled.

Expected/desired behavior

The drag hint should have the same height as the dragged event.

Workaround

move: function(e){
				
          var dragHintEl = $('.k-event-drag-hint')
          var dataUid = $('.k-event-drag-hint').attr('data-uid')
          var event = $('.k-event[data-uid="'+ dataUid +'"]:not(.k-event-drag-hint)')         
          var height = $(event).height()
          $(dragHintEl).height(height)

        },

Bug report

If an all-day event is resized to multiple days and then the user tries to resize the event back to one day, the event is not always resized.

Reproduction of the problem

1. Open the Scheduler Demos - https://demos.telerik.com/kendo-ui/scheduler/move-resize
2. Try to resize Alex`s birthday (06/14) or Bob's Birthday (on 06/29) to multiple days
3. Then try to resize the event back to a single day

Current behavior

The issue is occasionally reproducible and does not occur for all all-day events. The event is resized back only if the user tries to drag the mouse down and then resize. Here is a screencast - https://somup.com/cZeX6QpRlX.

Expected/desired behavior

It should be possible to resize back the all-day events back to one-day duration without moving the mouse down.

Hi,

I'm having some erratic behavior when displaying recurring events in the scheduler when the browser is Safari and in other browsers when the device is an ipad.

The recurring events don't show on the presentation table, but if I force several clicks in the presentation table with the intention of creating a new event and then canceling, they sometimes are rendered in the right slots. After they are rendered if I click the presentation table they disappear again.

If I check the scheduler dataSource data the events are there to be shown.

I tried to replicate the same behavior with the scheduler demo that you have available and I couldn't replicate it. But then I realized  that in my case only recurring events won't show up. My hint was that the problem was with the recurrence rule. I created a dojo sample with my recurrence rule and then the bug appeared.

Concluding it seems that for some recurrence rules the recurring events may have problems to be rendered in the presentation table.

Here is a dojo sample replicating the problem that I describe:

https://dojo.telerik.com/USiLEXAk

How can I resolve this problem or have a potential fix?

Kind regards,

Marco Miranda.

### Bug report

When using the Scheduler on a mobile device and trying to edit an existing event through the Month view, the editor template does not load the event details. The Scheduler opens an empty editor to create a new event.

### Reproduction of the problem

2) Open the Scheduler on a mobile device and select the Month view.

3) Try to edit an existing event.

4) The opened editor template does not load the event details.

A Dojo sample for reproduction: https://dojo.telerik.com/uherEWib

### Expected/desired behavior

The events must be editable when using the Month view, and the adaptive mode is enabled.

Bug report

When the timezone of the machine and the timezone set in the Scheduler are in different days, the currentTimeMarker is not displayed in the Timeline view.

Reproduction of the problem

1. Change the timezone of the machine to 'Fiji' or another timezone, thus the 'Honolulu and the chosen timezones are on different days. For example, when it is 3 am on 01.06 in Honolulu, it is 1 am on 02.06 in Fiji.
2. Open the Dojo linked here where the timezone is set to 'Pacific/Honolulu' - https://dojo.telerik.com/@NeliKondova/UVuDAJib

Current behavior

When the timezone of the machine and the timezone set in the Scheduler are in different days, the cusrrentTimeMarker is not displayed in the Timeline view.

Expected/desired behavior

The cusrrentTimeMarker should be displayed in all the views.

Environment

Bug report

Scheduler events in TimeLine view are displayed incorrectly when they start/end at the same time.

Reproduction of the problem

Run this dojo

Current behavior

Notice that Event 2 is displayed below Event 1, even though they do not overlap. Removing Event 3 results in Event 1 and 2 being rendered next to one another.

Expected/desired behavior

Event 2 should be displayed next to Event 1, but not below, as they do not overlap

This one is reproducible on the demo site today and that’s where this screenshot is from. Begin to create a new event. Set to recurring Monthly. Note that below “Never” is checked and the “10/11/2020” box is disabled. Now go and change your start date to any other date above. This box enables itself. It should not do this because the ending date option is not actually selected.

I fixed this in JavaScript by hooking into some events rather than modifying the Kendo.all.js file.

Bug report
