I just made a new view selector control that duplicates the view selector features of the built in one then hid the built in one with this:

span.k-scheduler-views-wrapper {
    display: none;
}   

Then I place my control in the spot where the built in one used to show.

Since the view is an enum, I just set it to null if the user has selected agenda mode then size the telerik control to just show the top like this. I might also conditionally hide the contents I can't remember. I also conditionally hide the footer.

<TelerikScheduler Data="@ScheduleState.Value.Appointments.Values" @bind-View="@CurrView" Height=@((!CurrButtonView.HasValue) ? "50px" : "100%") Width="100%" >

Then I make my agenda control conditionally visible.

The result looks identical to the control having the functionality built in.

 

 

Did you extend telerik's scheduler component? I considered trying to figure something out using their .net core implementation.

it wasnt too hard making my own the worst part was hiding the telerik view selector and replacing it with my own day/week/agenda selector.

This has become a big issue for us.  The only solution I have at this point is to switch the team to syncfusion set of components.

I feel like this should be in the road map, but I don't see when it's available. 

I guess I'll create my own component until then, taking inspiration from the Angular one f.x.
