Bug report

Recurring events are not rendered on the correct date when an event has to be displayed on different dates in different time zones.

Reproduction of the problem

1. In our demos or the Dojo linked here create an event with starting time of 09 AM. Set the event to repeat every Monday. In the example below the timezone of the machine and the event is UTC +2 (Sofia)

Below are two events recurring and nonrecurring created with the same starting date and time in UTC +2

1. To simulate opening in different time zones change the Timezone on the machine with a difference of more than -9 hours, so the event to be expected to display on the previous day. For example, select UTS -10 Hawaii.

Current behavior

After changing the time zone on the machine from UTC +2 to UTC -10 the event is rendered at 8 PM, but it is still displayed on Monday. Thus, recurring and non-recurring events created with the same start date and time are displayed on different days when the time zone is changed:

Expected/desired behavior

The date of the recurring event should be changed according to the time zone. It should be possible to repeat events on a different days of the week when the Scheduler is opened at different timezone

Hi, we're using scheduler and we have the selectable set to true so users can drag and select timeslots to create.

The issue we're having is related to the autoscrolling when the user attempts to create a selection that is longer than the display window and attempts to drag past the display window but the scheduler would not auto scroll to expand the selection.

However, if we were to expand an existing event, the handler would be able to expand past the display window and scheduler would auto scroll. We were wondering if the event creation could have the same behavior.

 

Thanks,

Kenneth

Hi Team,

I want the scheduler to respond to mobile phones and tablets, e.g. I have many columns in the day view. I want to have specific columns, e.g. the first 2 or 3 to be visible and the rest to scroll horizontally so that you can see them within the scheduler and not have to scroll the page horizontally.

Thank you!

Bug report

On Safari, the Scheduler throws an error.

Reproduction of the problem

1. Open Timeline view in jQuery Scheduler Widget Demo | Kendo UI for jQuery (https://demos.telerik.com/kendo-ui/scheduler/timeline) 

2. Edit in Kendo UI Dojo

3. Edit an event using the scheduler's event editor so that it is multi day, begins a week prior and ends at the start of the second day of a week at the time of a work day (Event: 06/02/2025 8AM - 06/10/2025 8 AM) (see attached screenshot)

4. Switch to "Work hours" instead of "Full day" view

=> The event is incorrectly displayed, missing a whole day.

When using the workWeek view with workWeekStart set to a higher value than workWeekEnd (e.g., 6 to 5), the scheduler calculates a work week that does not include the current day. As a result, clicking the "Today" button may not display the actual current date if it falls outside the computed work week range. Instead, the scheduler navigates to the work week defined by the configured start and end days.

Hi,

I'm trying to define individual business hours for the scheduler. The  scheduler only uses a single start/end time for each work day. I want to define start/end times for each day specifically (ie. Monday has different times than Tuesday).
Eg:
Sunday working hours       @ 10:00 to 12:00
Monday working hours       @ 9:00 to 16:00
Tuesday working hours      @ 10:00 to 18:00
Wednesday working hours@ 06:00 to 12:00
Thursday working hours     @ 08:00 to 14:00
Friday working hours           @ 11:00 to 12:00
Saturday working hours      @ 11:30 to 13:00

Can anyone resolve my problem.

Thanks in advance

We have a need to be able to provide a dropdown above the scheduler, in order to allow the end user to change the time zone of the scheduler dynamically, even after it has been initialized.  Our team was disappointed that this is currently not possible (http://www.telerik.com/forums/timezone-dropdown), but maybe in the future.  Thanks for reading.

Hi Team,

I would like to request a way to incorporate adding a reference to the model for group cells in the Kendo UI Scheduler.  Perhaps using a uid for the cell may help. 

Thank you!
