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

The current functionality allows dragging items from an external component to the Scheduler, but not the other way around. I would like to be able to drag and drop appointments between multiple Schedulers.

The "Edit Recurring Appointment" modal is only partially visible on mobile which prevents the user from proper editing.

Hello, 

 

I use the scheduler component with grouping ressources on a timeline view. 

When there is only one ressource for the second group, there is no text showing on the view.

It works with 2 ressources.

I try over your demo and i have the same result.

When I use 2 ressources it works.

Thank you

 

I'd like to have a data virtualization feature (similar to the OnRead event), so I can load only small chunks of data (appointments) specifically for the current page/view.

Currently, you can achieve similar functionality by handling the DateChanged and ViewChanged events of the Scheduler to load only the relevant appointments for the selected period.

You can find an example here: Load Scheduler Appointments on Demand.

The Timeline view currently does not provide the "Show business hours" option as in the other views.

Please add that for the Timeline view similar to the jQuery version of the component.

For the time being, you can achieve this functionality with a custom approach by programmatically setting the StartTime and EndTime of the view to equal the WorkDayStart and WorkDayEnd.

Here is a basic example: https://blazorrepl.telerik.com/QyEhvjbO07j1ZvID42.

Hello,

It would be nice if there was a way to indicate to the user that there are events earlier or later in the day that are not in the current viewable area.

That's pretty weird but nevertheless very specific: if the Scheduler is loaded with POCO objects from EntityFramework with LazyLoading enabled (Castle.Proxies objects) them the k-event-drag-hint box is not shown (!)

 

It took me some time to figure it out...

I am using resource grouping with Day view only. I have 5 groups and showing the date for each column/group is repetitive, and a waste of screen space. I want to remove the date header as I am already displaying the date in a different element on the page.

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

When the Scheduler works with a large dataset the rendering can get laggy. I need to use a rendering optimization feature such as the virtual scrolling in the Grid. 

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 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.

The Start and End properties provide only the dates but not the time. 

The appointment drag and drop functionality of the Scheduler does not work on mobile devices. When you try to drag an item, the item does not move.

You can test it by running the Scheduler overview demo by using Chrome's mobile device emulator and trying to drag and drop an appointment.

Currently, I'm making specific cells undroppable zones by conditionally executing the logic inside the OnUpdate handler. When I drag over a cell that does not allow dropping in the Scheduler, I want the hint to indicate an undroppable zone.

I am using resources in the scheduler and I need to require the user to select a resource from the list when adding an appointment. Maybe a "Required" option when you declare the resource?

ADMIN EDIT

At the moment, a custom edit form is the only option: https://github.com/telerik/blazor-ui/tree/master/scheduler/custom-edit-form

If you need to add resources only in one mode (edit or insert), please provide an example of how you would expect that to be controller through data annotations since they would be in effect in both modes if used.

---

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.

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.

Currently, creating an appointment is made by double clicking on a slot. The case of single clicking to create an appointment is already in another request.

If you take the example of Google agenda, you can create an appointment by selecting directly the dates by sweeping with one long single click.

Here would be the request:

An event similar to SchedulerEditEventArgs (containing Start, End, IsAllDay, IsNew ; IsCancelled: to be able to have a custom edit form) that would be triggered with one long single click selecting the dates/hours slots of the appointment.

Although the discussion targets different functionality, we are keeping the current request open as we consider it valid to ensure better UX for appointment creation on mobile devices and we would like to see how the demand for that goes.
