When SchedulerGroupOrientation is set to vertical, increasing the height of the `SchedulerResourceGroupHeader` breaks the rendering of the Scheduler cells, which causes misalignment of the appointments. In my scenario, I want to have a Button and an Icon in the group header cell.

When I try to move by drag and drop  an event between resources the resource on the event is not updated.

I used this

At the moment start and end times effectively "round" to the nearest half an hour.   This can give the impression of events overlapping when they do not

e.g.

Admin edit: This feature would be similar to the Exact Time Rendering in our WebForms suite: https://demos.telerik.com/aspnet-ajax/scheduler/examples/exacttimerendering/defaultcs.aspx

If the Scheduler is placed in a parent container (for example Telerik Splitter or any other container) its appointments are not resized when resizing the pane. The Scheduler itself resizes accordingly, but the appointments don't.

Is there a way to customize the resource grouping's header (i.e. Alex, Bob, Charlie)? I understand it displays the text from the Resource, but I would like to be able to customize the HTML displayed so that I can add a tooltip. Would you have a suggestion as to how I can accomplish this?

Kendo Group Header Template

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

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

Other schedule controls have an 'agenda' view that has a chronological list of appointments back to back stacked vertically colored by resource.

It would be great for the telerik scheduler to have a view like this.

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:

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.

I want to hide the 'All Day slot'  - I don't want to offer this functionality.

At the moment, you could try CSS like this, but ideally this would be a parameter (maybe on the view):

        .no-allday .k-scheduler-head .k-scheduler-group:last-child{
            display:none;
        }

    <div class="no-allday">
        <TelerikScheduler Data="@Appointments" @bind-Date="@StartDate" @bind-View="@CurrView" Height="600px" Width="800px">
            <SchedulerViews>
                <SchedulerDayView StartTime="@DayStart" />
                <SchedulerWeekView StartTime="@DayStart" />
                <SchedulerMultiDayView StartTime="@DayStart" NumberOfDays="10" />
            </SchedulerViews>
        </TelerikScheduler>
    </div>

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

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:

1. Load Timeline View Demo
2. 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)...

• not working version (4.2.0)...

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.
