I want to be able to limit the Scheduler to a minimum and/or maximum date.

This request could be revised in two separate tracks:

• Min and Max parameters on component level regardless of the selected view
• Min and Max parameters for the separate views ( Day, Week, Month etc.)

Please share your thoughts on how you'd expect it to be implemented.

Now that we can have more than 2 events in a day in Month View, we need to add an AppointmentHeight parameter to be able to make the appointments taller in height to accommodate longer titles.

ADMIN EDIT

An alternative for the time being is to show the longer content by using the appointment templates and the Tooltip component. For example:

https://github.com/telerik/blazor-ui/tree/master/scheduler/appointment-tooltips

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 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>

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.

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 am really looking to try to do something like this in Blazor: ASP.NET MVC Scheduler Hierarchical Grouping Demo | Telerik UI for ASP.NET MVC

In MVC, this feature is implemented with the dataParentValueField.

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.

I want to easily print the Scheduler calendar - month view, week view and more.

===

ADMIN EDIT

A possible approach for the time being is to implement printing functionality for the Scheduler in a similar fashion to how the Grid is printed here https://github.com/telerik/blazor-ui/tree/master/grid/print.

The approach relies on using JavaScript to invoke the browser print() method. Using CSS and @media print, you can customize the page and specify which elements should be visible when printing. For example, you may hide the toolbar and footer of the component, so only the calendar is visible.

Here is a runnable sample that demonstrates the approach: https://blazorrepl.telerik.com/cnutklOC55T5sV0J15.

I want to add more fields to the scheduler create/edit popup. Currently, this is possible by creating a custom edit form. However, this customization would be easier if the Scheduler exposed a Popup Form Template similar to the Grid.

===

ADMIN EDIT

A necessary prerequisite for exposing this is to first add a State feature in the Scheduler. This will allow programmatic control over the edited item.

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.

Support the recurrence rule to create multiple appointments per time slot. Examples of such rules are:

FREQ=DAILY;BYDAY=MO,TU,WE,TH,FR,SA,SU;BYHOUR=08,09,10,11,12,13,14,15,16;BYMINUTE=50

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.

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.

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

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.

Our current implementation of the JQuery version of the scheduler uses custom views. I understand that custom views are going to be a difficult if not impossible task for Blazor rendering. The goal for our custom view is simple, we override the calculateDateRange function to supply an ordered date range that allows us to have a "TimelineTwoWorkWeekView", thus showing Monday-Friday then Monday-Friday again. We also had a use case that was never implemented but would be addressed the same way; to show all "mondays this month".

Therefore, the request is a "TimelineCollectionView", displaying a timeline view for dates specified in an IEnumerable<DateTime>.

Any other ideas or feedback would be greatly appreciated.

The edit popup currently does not adapt to screen size changes. Part of the edit window for the scheduler is off the screen making it unreadable on certain resolutions.

I need to make it responsive/adaptive.
