### Bug report

When typing in the built-in search box of the Scheduler, the spacebar does not insert a blank space as expected.

### Reproduction of the problem

Type in any word in the search tool and press the spacebar.

A Dojo sample for reproduction: https://demos.telerik.com/kendo-ui/scheduler/search-events

When using Kendo version 2021.3.1109 in the same scenario, the spacebar opens the Popup form for event editing.

### Expected/desired behavior

When you press the spacebar, it should insert a blank space.

Bug report

When the dataSource for the resources is empty and the Month view is selected the 'Cannot read property 'firstChild' of undefined error is thrown in Scheduler.

Reproduction of the problem

Current behavior

'Cannot read property 'firstChild' of undefined error is thrown in Scheduler when the Month view is selected.

Expected/desired behavior

No error should be thrown with an empty resources dataSource in Scheduler.

The issue is a regression starting with 2020 R1 (2020.1.114) release

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

Is it possible to implement an option to show only the workdays in the Scheduler Month View?

Currently, the default start and end dates in the Agenda view can be edited only if we use a custom view.

It will be very easy for the users if we can just pass these dates as a property. 

When setting a timeline view to display as an overnight view have an option to highlight the midnight timeline. This is currently only possible via a complex set of css rules...

you could have something like...

highlightTime: {time: 0, color:#ff0000}

where time is the timeline that needs to be highlighted and color is the color the line should be.

I have a need to create an event that will indicate a resources availability. This only needs to be a thin coloured block. Actual events will then be created along side the 'Availability' block. Basically we have the ability to create an event template. Need to be able to create two have assign the correct template based on what type of event it is. Also need the availability event to be rendered first so that it is always to the left on vertical views and at the top in horizontal views.

Your recent feature to allow the start and end times to be altered in a timeline view so that you can configure an overnight view is very useful. Could the same facility be provided for the Day, Week and WorkWeek views.

Currently the scheduler 'snap' option does not actually snap to the nearest time slot, rather it adjusts the start time +/- the 'majorTick` amount of an event.  So an event scheduled at 8:03 am would snap to 7:33 am or 8:33 am, given a 30 minute 'majorTick'.

I would be helpful to have another option that allows the event to actually snap to the nearest time slot.  So that same 8:03am would snap to 8:00am, 7:30am, or 8:30am.

We can get a string like FREQ=MONTHLY;INTERVAL=2;COUNT=2;BYMONTHDAY=19 but it would be great if there was an option to get a more readable format of the recurrence for labeling purposes (if you cannot already, I cannot find any documentation saying you can). Like, 'Recurring Every 2 months on the 19th, twice' or some such.

Currently, the moveEnd handler contains e.slot and e.resources objects to provide information about the slot where the event was dropped. Please add the corresponding fields to the moveStart handler to identify where the move began.

New edit mode:  When events are retrieved, those models should always be as lightweight as possible (id, start, end, title), and not include all the other properties required to edit an event.

If you have hundreds of events with lots of properties, your control does not scale well.  When you then edit one of these lightweight events, it should make an ajax request to go fetch the "full" model used to populate the edit popup window.  For the create, it may not have to make an ajax request, but the "full" schema needs to be defined still, so it has a model to bind, and it would be nice to have a way to dynamically specify that schema, in case you have different event model types.  In my case, I have three different types of appointments the user can create/edit.  Ideally, these "full" models would either get sent via ajax when the popup is closed, or when the datasource is synced, they get trimmed down to the lightweight version.  Hopefully this all makes sense...it's all about having tiny models for speed, but larger models for editing.  Anyone that has used your control to show tons of appointments (especially with many properties each) will likely get where I am going with this.

Scheduler should support template directives for the group header template option.

When the dates for the current view are changed in Scheduler, the screenreaders do not read the new date.

Reproduction of the problem

1. Go to Keyboard Navigation Demo
2. Go to the arrow buttons in the toolbar and click 'Next' to change the date
3. Date changes to "Sunday, June 16, 2013 - ..."

Current behavior
The screenreaders do not inform the user that the date has been changed.

Expected/desired behavior
The user should be informed that the date has been changed.

Hi,

We have a requirement where in, we would like to have rolling view for the standard timeline views (timelineweek & timelineMonth).

What i mean by that is, the start-date of the view starts from the current date and the end date is based on whether its a week or a month.
For instance, if its the timeline week, if the current day is Wednesday, the start day of the week must be the current Wednesday and the end should be the next week's Tuesday.
The navigation from there should be the next Wednesday to the next corresponding Tuesday.

Now if the user navigates to a day via the calendar, for instance a Thursday. The view must start from a Thursday and end on a Wednesday.
The same applies for the timelinemonth view as well. Only change would be, in the case of the month, its the date and not the day.

Currently this can be achieved by creating a custom-view by extending the standard views.
It would be really helpful if this is available as toggle/setting in the standard view.

Thanks,
Shashank

We are looking into the scheduler but it seems to be missing a feature that we would really want in a scheduler.

If you are for example in the day view, you have left the timebar and right the events. It would be nice to zoom in on the times on the left.

instead of showing events from daystart - day end you would click on a chosen starttime drag to the endtime you wish and the scheduler would zoom in on items between the selected start- endtime.

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/aGidAkuP/2

1. Double click an event to edit it.
2. Enter and invalid hour (e.g., 25:00) or some text in the Start or the End DateTimePicker.
3. Click the "Save" button.

Current behavior

The validation message appears for a fraction of a second and then disappears. No indication of which field is invalid remains. If a SASS theme is used, there is some indication - a red border around the invalid field appears.

Expected/desired behavior

The validation message remains until a valid date is entered in the DateTimePicker.
