When I change the date while I'm in the month view, the slot doesn't change to the newly calculated ItemsPerSlot value.

To reproduce, open the calendar and set the date to the 3rd of December: REPL link.

When creating an appointment, the Start and End editors should display the date (and time) of the slot the user clicked on.

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:

https://demos.telerik.com/blazor-ui/scheduler/multiday-view

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.

ADMIN EDIT

Possible workarounds:

1. 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.
   
   
2. 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 try to click on the Save button in an Event Scheduler Popup window, an error appears.

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.

By design, the appointments should be resized and repositioned upon browser resize. As of UI for Blazor 3.7., the appointments are not properly scaled upon browser resize.

The Scheduler seems to be showing the previous month in the header.

<TelerikScheduler AllowCreate="@Editing" AllowDelete="@Editing" AllowUpdate="@Editing" OnDelete="@AppointmentDelete" OnEdit="@AppointmentEdit" OnUpdate="AppointmentUpdate"  Data=…

The above line breaks only with AllowUpdate.

I default Editing false, then toggle it true in the hosting component and do a InvokeAsync(StateHasChanged). 

The result is I can create and delete, but while the appointment hover cursor changes to the hand or arrows and I can see the handlebars to resize the appointment, I'm not able to update the appointment until I switch the SchedulerView. After switching SchedulerView updating works as expected.

If you drag an occurrence to a different time slot, a new appointment is created and the series is accordingly updated. However, if you are editing an occurrence via the edit form to change its start and end, a new appointment is correctly created but the initial occurrence remains not updated in the series.

Can be reproduced in the Appointment Editing demo.

I have located an issue with the scheduler in Firefox

It currently is not possible to edit an appointment in Firefox when visiting the following demo page:

https://demos.telerik.com/blazor-ui/scheduler/appointment-editing

Edge and Chrome work as expected.

I noticed this issue in my local project and referred to the demo's to see if I was doing something stupid :-).

I am assuming that the demo's are running in .net 5 and that the demo's are blazor server applications.

When you try to group by resource with a type different of string (long, int, etc.), an "Error: System.ArgumentException: Arg_ObjObjEx" appears.

When you drag or resize an appointment, its start and end fields in the Scheduler data are updated before any logic in the OnUpdate handler is performed. Thus, if you want to prevent the update based on some condition, you are not able to do so when drag or resize.

When the view modes options (Month, day, week, etc...) is collapsed and the arrow is clicked, the drop menu shows behind the main scheduler window.
