When adding / editing the last time slot for the day, SchedulerEditEventArgs has wrong End value.
For example Start value is 28.12.2023. 23:30:00 and end value is 28.12.2023. 00:00:00. Should instead be 28.12.2023. 23:59:59 or 29.12.2023. 00:00:00.
Hello!
After update to 2.27 there is a bug to scheduler with number of days and refresh.
You can check your live demo also:
In a Scheduler with vertical grouping, I am dynamically changing the displayed resources during runtime. It looks like displaying a longer resource name breaks the rendering.
The Scheduler does not recalculate the cell width when changing the resource list.

Possible workarounds:
- Force component rerendering when changing the resources list - dispose it and initialize it again using a flag and conditional rendering. Example: https://blazorrepl.telerik.com/wwuDGLvE42TUf5En09.
- Use CSS to set appropriate min-width to the resource cell, so it is wide enough to fit the longest name of the available resources. Example: https://blazorrepl.telerik.com/wmaDGhFY37t5pFj757.
When using Vertical Grouping by multiple resources and Timeline View, the group rows without appointments do not have min-height as the rest of the group rows. Thus, they appear shorter which causes an offset of the events on the next rows.
Steps to reproduce:
- Load Timeline View Demo
- Delete Charlie's event in Small meeting room

A possible workaround for the time being is to set min-height to all rows. Apply this style only when Timeline view is selected, so this does not break the rendering of the other views.
Example: https://blazorrepl.telerik.com/mHYmwsOt30fjTZ6a32.
I am using a Scheduler with vertical grouping by multiple resources. In Timeline view, some of the appointments appear with an offset and are not correctly aligned in the cell. In some cases, the appointment is even rendered outside the slot it is associated with.
The issue seems to occur as of UI for Blazor 4.2.0. The same configuration worked fine in 4.1.0.
- working version (4.1.0)...

I am using the Scheduler component in Telerik for Blazor and am getting an intermittent exception being thrown, usually when navigating quickly through the application (ie. navigating to another page before the initial page containing the Scheduler has finished rendering).
This is the exception received:

ADMIN EDIT

The Scheduler must render in the browser and then it measures and adjusts its layout with JavaScript. You may hit this error if the component is disposed before or during this JavaScript call.
Example use cases:
- Navigating to a different page before the full component initialization
Workaround:
The possibility to hit that is higher in case the Scheduler needs more time to initialize (e.g. it has to render a large set of appointments). In such a scenario, it will be useful to optimize the time needed for loading the appointments, so that the initial component rendering is not blocked by waiting all the data. For that purpose, you may load the appointments on demand - not fetching all possible appointments at once, but only when the user should see them. An example of such an implementation you may find here: https://github.com/telerik/blazor-ui/tree/master/scheduler/load-appointments-on-demand. - Disposing the component during runtime (e.g. depending on the screen size) - https://blazorrepl.telerik.com/wIuHliEt40SutaBI53.
Workaround:
Potential solution in this case - render component after calculating the screen size: https://blazorrepl.telerik.com/coEnPWON4570Wna007.
Check the following configuration: https://blazorrepl.telerik.com/cHvuPOYX27peykXr18 ( SlotDuration="720" SlotDivisions="1").
The start time of the appointment is 12:00 PM today. The Scheduler, however, displays the start at 12:00 AM on the next day even though the arrow indicates the event continues from the previous day.
For reference, if I set SlotDivisions="2", I get the expected result: https://blazorrepl.telerik.com/GxFOvYED302CzPCo32.
The appointments at the start of the day seem accurate. If you scroll down, the position of the appointments does not line up with the grid line for the hour that it starts at or ends at. The issue can be observed in the live demo.
I am trying to look at the times 7pm - midnight. But if I set the end time to midnight, I get an error that the end time has to be greater than the start time. How do I set the timeline to show 7pm - midnight or 8pm - 2am?
I tried including the next date in the EndTime but the Scheduler does not take the date into consideration, it checks only the time portion.

If the Start and End match exactly, the rendering of the Scheduler breaks in Day view. If another view is used, the event looks as if it is rendered on the previous day.

ADMIN EDIT

A possible workaround for the time being is to use a custom edit form and implement some kind of validation that prevents the user from selecting the same value for the Start and End of an event.
If I change the width of the scheduler component it doesn't move the events to the correct place
I am currentl looking at printing the Scheduler but I ran into this issue when trying to adjust the scheduler to fit on a page
When the Week view of the Scheduler is selected the label of the DatePicker is incorrect. The displayed range in the label covers an extra day. e.g. in the Week view the range spans 7 days (the label show range of 8 days)
The problem can also be observed when the MultiDay view is selected - the displayed range includes one additional day.
I have a problem with Scheduler TimelineView. When there are a bit more appointments in the first resource group, the last appointment from the last group is positioned incorrectly/outside of the Scheduler component.
I think the CSS parameter "top" is calculated in the wrong mode. See the attached recording.
If the Start and/or End fields are DateTime? double-clicking on an empty slot does not open the form. This makes it impossible to create new events.
The issue occurs as of UI for Blazor 3.7.0.
Reproduction: https://blazorrepl.telerik.com/mnEHQNvl48HDc8xb30.
When you have an event that starts between 11:30pm and 12:00am - the default last slot of the Timeline view, the Scheduler throws the following error:
Error: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection
Scheduler cells are not aligned correctly in the Timeline View when Bootstrap Theme is used.
To reproduce the problem:
1. Open the following Scheduler Demo:
https://demos.telerik.com/blazor-ui/scheduler/overview
2. Select the Bootstrap Theme
3. Open the Timeline View
The Scheduler seems to be showing the previous month in the header.
