Add And Remove Items when Collection is Changed

[bbaileyHOM]

First, thank you for doing the leg work on making this work in Blazor!

Is there a reason that the items on the calendar aren't updated with the Schedules collection is changed? Is there another way in which changes to the calendar are expected to be add/removed from the calendar? I wasn't able to determine if there was.

I downloaded the project and the made the following changes to TUISchedule.cs:

added:
private ICollection<TUISchedule> _schedules;

altered:

        [Parameter]
        public ICollection<TUISchedule> Schedules
        {
            get => _schedules;
            set
            {
                _schedules = value;
                
                if (_schedules == null || CalendarInterop == null) return;

                ClearCalendar();
                CalendarInterop.CreateSchedulesAsync(_schedules);

                InvokeAsync(StateHasChanged);
            }
        }

Any time the collection changes the calendar is cleared and all schedules are recreated. It might be better to use ObservableCollection and add/remove/update but that is a bit more complicated and I am not sure if there is a lot of value in it.

Thanks, I'm happy to contribute the community. And thanks for the idea and thoughts!

Updates can come from the UI and those changes are synced with collection.

Correct me if I misunderstood, I think you're wanting to make changes or add events from code/server-side/C# and push just those incremental schedules down to the calendar?

Happy to collaborate, just want to make sure I'm in the same page.

Yes, I'm essentially posting items to the calendar that I have in a database. And in my case they aren't points in time but schedules with occurrence rules so I'm not even using the built in functionality for creating the items.

I believe TUI supports recurrence rules. Have you tried calling CreateSchedulesAsync method in the interop? I wonder if that will help you to add schedules from code.

I had thought that I had tried using that method and it wasn't working for me for some reason, but I just tried it again and that works as well.

From what I have read TUI doesn't have built in recurrence functionality but provides a property for implementing if you like. And that wouldn't probably work well for me anyway.

Thanks again!
