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. 

 

When the slotByElement method is used for multiple elements this could lead to performance issues in Scheduler.
For example, the difference in the performance can be observed in the Dojo examples linked below when loading the Scheduler and when changing the selected resources:

Dojo with 2023.1.314 - https://dojo.telerik.com/@NeliKondova/UJOcEJoC

Dojo with 2023.1.425 - https://dojo.telerik.com/@NeliKondova/UHisivuC

The issue occurs starting with the 2023 R1 SP1 release and could be due to the following fix - #7260

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

Environment

• Kendo UI version: 2020.2.513
• Browser: [all]

It would be great to be able to customize the scheduler's toolbar, either by specify custom buttons and actions through 'toolbar' option or by providing a custom template.

I just upgraded to the latest version today.

kendoScheduler doesn't fire change event when in "Year" view.

This is really easy to duplicate. Select Year and it doesn't fire.

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

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

Reproduction of the problem

1. Run this dojo.
2. Create a recurring event, for example weekly, each Monday, starting on 6/3/2013, and set End to Never.
3. Save event.
4. Edit the series.
5. Change the start and end date to 6/4/2013.

Current behavior

Validation error is displayed.
screencast

Expected/desired behavior

Validation error should not be present in this scenario.

Environment

• Kendo UI version: 2022.3.1109
• Browser: [all]

Bug report

The recurring events are not rendered as expected in some scenarios depending on the start time set.

Reproduction of the problem

1. Open the Dojo
   The difference between the first and the second event is the start time.

Current behavior

The first event is not rendered for every week, but it is rendered for every second week.

Expected/desired behavior

When the recurring rule is 'FREQ=WEEKLY' the event should be displayed every week, despite of its starting time.

The issue is a regression. The last working version is 2020 R1 SP1 (2020.1.219).

In 2020 R1 SP2 (2020.1.406) there is a bug related to missing events fixed with 2020.2.513. - Dojo with 2020.1.406
Starting with 2020 R2 (2020.2.513) the current behavior is introduced.

The issue might be related also to: #5978

Environment

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

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

1. Open the Dojo and observe the browser console https://dojo.telerik.com/@NeliKondova/IvIJeLAw

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

When you right click on an event to open a ContextMenu in the Scheduler, the first row is selected.

Regression introduced with 2022.1.301

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/aCEtARaH/22
2. Right-click on a event cell

Current behavior

The first row is selected

Expected/desired behavior

The targeted row should be selected

Environment

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.

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.

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.

Environment
Kendo UI version: 2021.2.616
Browser: [all ]

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.

There should be a way to programmatically get the selected timeslots from the scheduler. This might need to have the ability to not lose focus on blur of scheduler
