Bug report

Reproduction of the problem

2. Try to change the start/end of the events by dragging

The issue is related to the used theme. The behavior is correct when using the themes version 12.0.0

Bug report

In the Scheduler, if we have a slotTemplate and at the same time views.virtual, the resources().field in the slotTemplate always returns the same value (of the first resource).

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/lJnddiLz

Current behavior

The data-resource='#= resources().user_id #' in the slotTemplate always has the same value.
If the virtual is disabled, the data-resource='#= resources().user_id #' has a value based on the resource.

Expected/desired behavior

The resources should be correctly returned in the slotTemplate even if the virtual option is enabled.

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!

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!

Bug report

Reproduction of the problem

Reproducible in the Events demo.

1. In the AllDay slot click and drag the mouse from Monday to Wednesday.
2. The change event fires 3 times (expected).
3. Click on Wednesday to select only that slot.
4. The change event does not fire.

Also reproducible when selecting the slots from right to left (Wed to Mon) and then selecting the last slot (Mon).

The behavior is identical when selecting slots in a specific day, e.g. selecting and dragging from 8:00 to 10:00 and then selecting the last slot (9:30-10:00).

Current behavior

The change event does not fire.

Expected/desired behavior

The change event fires.
