In my application, when a user changes their view date on the scheduler, there are two other schedulers on the other two tabs of the tab strip that are not visible. The dates here get changed too. This happens in a navigate event. They end up in a broken state from this. It seems the issue is that they are not visible so rendering is not happening. I found a hacky way to work around this. I am adding a newDate property and a needRefresh property to the scheduler. When a tab is activated, the scheduler in that tab is checked. If it needs a refresh, it is refreshed. If it has a new date, that is also set.
In the scheduler component, create a new event. Select monthly for the repeat. If you are using the Bootstrap theme the day will be cut off. The problem lies in the kendo.common-bootstrap.css file.
Overriding to 10em works. The same issue exists on the demo site today which I assume is running the current version (https://demos.telerik.com/kendo-ui/scheduler/index?autoRun=true&theme=bootstrap-main):
I have some client events for creating/updating events.
They are currently the same and call the same method:
We run into an error on random occasions. This happens maybe once a day per user. It is not repeatable but it was fixable. This code is from the Kendo.all.js file. The highlighted lines were added:
Here is the text from the browser’s F12 window when we hit this error (If I have not applied the fix above):

I have a number of DataSource items in the event editor template. They are small JSON objects and it would be dumb to read them from the server each time. They do not change and are part of the page load. You can see here I am just serializing them into the page itself:
This works 9 out of 10 times. But sometimes the dataset is empty. Which is crazy because I am always filling it. I managed to find a work around on the event edit event that gets called but this seems strange to do. Not sure if there is a true bug here or not. Feels like it because this code should not have been needed:
The schedulers are sitting inside a tab strip control. When the page loads, some computations are done by Kendo for setting up column widths. I feel there is a scrollbar issue somewhere. As it is a larger screenshot, please look at the attached Scrollbar size computation issue.png file. Start with the “All day” events. Notice the first event on Monday crosses the line into Tuesday just a little bit. This is highlighted and indicated with a “2” on it. Now look at the events for the week – numbers 3, 4, and 5. The events span into the next column a little more each time. They WOULD be correct if there was no scrollbar on the right! Now look at the events below with a time. “1” has the correct left offset from Monday’s left side. As you go to 2, 3, 4, and 5, this offset grows. It’s the same issue.
Now look down at “6”. Notice the scheduler has no footer and is drawing far too low.
The problem is that the tabstrip content is allowing scrolling. I can see this in the F12 window. Notice the scheduler does not have the scrollbar:
But the tab strip content DOES have a scrollbar:
Please note that I am specifically blocking the tab strip from scrolling in my code. The scheduler should handle the scroll.
So, I added the following CSS which fixes this issue for me:
See the Scrollbar size computation fixed.png file for the end result. The scheduler is scrolling now instead of the tab strip.
We are using the columns.filterable.ui to initialize a kendoTextArea, if we write something and use the enter key to filter the value is ignored.
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 have an event template. Inside this template I am using a MultiSelect. It is defined like: <select data-down-Arrow="true"… . The downArrow property does not work. I discovered via debugging the kendo.all.js file the problem. Fortunately this one is fixable outside that file:
When you collapse a selected task in the Gantt, the selection is lost
The selection is lost
The selection should be preserved
My recurrence rule is: FREQ=MONTHLY;COUNT=2;INTERVAL=1;BYSETPOS=2;BYDAY=WE;WKST=SU. This event falls on the second Wednesday of the month for two months in a row. When I edit the event, the wrong option is picked. Note in the screenshot attached we are on 11/09/2022 which is the second Wednesday. And the scheduler correctly shows this event. But the edit window sets the properties wrong. I am using a custom template for the edit window, however the recurrence editor portion is unmodified.
I was able to fix this in the Kendo.all.js file directly. The highlighted lines below were added. When I publish this for customers I use the Kendo custom download tool to get a minified script of only what I need. I then need to carefully port this change using Notepad++. This makes it tough to update versions which is why I am a few versions back.
From the kendo.common-bootstrap.css file:
This cuts off the dates which have ample room to be displayed (this is my app):
I overrode this to remove the max-width:

kendoScheduler doesn't fire change event when in "Year" view.
This is really easy to duplicate. Select Year and it doesn't fire.
Optionally allow for the disabling of Daylight Savings time detection when using the DateTime picker, or to set the TimeZone for the picker manually.

Editing a recurrent event in the Scheduler with End options set to
Never triggers validation on the DatePicker.
This is a regression introduced with R1 of 2022
Validation error is displayed.
Validation error should not be present in this scenario.
The scheduler is either editable or not. And deletion events are either allowed or not. This isn't a black and white thing. Consider employees at a store. They can see each other's events for scheduling but they are only allowed to modify their own events. So I want editing and deleting enabled but conditionally.
In my case I hook into the databound event and I add a class "nodelete" on events that cannot be deleted. Then I have CSS that hides the "X" button on hover and I block the edit window from appearing.
However, the keyboard still prompts for a deletion. I think there should be some function for whether an event is editable. That, or an event should fire before the deletion prompt so I can stop it from occurring.
Here's a hacky work around. I don't like accessing properties starting with underbar as they are considered private and subject to change but I don't see a better way.
