When Scheduler data is loading, while waiting for the server response, there is no loading indicator rendered for the Agenda view. For example, such an indicator is displayed when loading the data in Day, Month, Timeline views. I would like to have the loading indicator in the Agenda view as well.

Bug report

The empty space next to the event is needed if we want to add new event next to the one that we already have so it should be observed only if the editable setting is not false or {create: false}. If any of these is set the event should be 100%. https://demos.telerik.com/kendo-ui/scheduler/basic-usage

Reproduction of the problem

https://dojo.telerik.com/@zdravkov/uWExofIL

Current behavior

the event width takes all 90% of the width of the slot

Expected/desired behavior

the event width should take all the width of the slot

Hi Team,

I'd like to request the functionality to have built-in Editor Button Template for the Kendo UI Scheduler's Event editor window instead of having to prepend and append to the k-edit-buttons class element.  

Thank you!

Please investigate this dojo sample:

https://dojo.telerik.com/IjIminuv

Even looking at the built-in Timeline view, one can see that the bottom gap is thinner in every group. However, switching to the TimelineEx view (that sets BottomRowOffset to 0), the problem is obvious...

Please address this computation error in the row-height...

Regards

I would like to be able to only see the days for the selected month when in month view.  Currently the calendar shows a set number of weeks and includes days from the previous/next month.   Some kind of setting to only show the days for the current month would be great.

See https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/how-to/appearance/set-event-color-in-the-template

The example shows how to style the content of the event, but borders stay in the old color.

Additionally, images are broken.

Hi,

I'm having some erratic behavior when displaying recurring events in the scheduler when the browser is Safari and in other browsers when the device is an ipad.

The recurring events don't show on the presentation table, but if I force several clicks in the presentation table with the intention of creating a new event and then canceling, they sometimes are rendered in the right slots. After they are rendered if I click the presentation table they disappear again.

If I check the scheduler dataSource data the events are there to be shown.

I tried to replicate the same behavior with the scheduler demo that you have available and I couldn't replicate it. But then I realized  that in my case only recurring events won't show up. My hint was that the problem was with the recurrence rule. I created a dojo sample with my recurrence rule and then the bug appeared.

Concluding it seems that for some recurrence rules the recurring events may have problems to be rendered in the presentation table.

Here is a dojo sample replicating the problem that I describe:

https://dojo.telerik.com/USiLEXAk

 

How can I resolve this problem or have a potential fix?

Kind regards,

Marco Miranda.

Hi, we found a performance issue that occurs only in the "agenda" view, specially when events have several days of duration.

Look at this dojo.

https://dojo.telerik.com/@foxontherock/IZafonEW

In the "week" view, navigation from week to week is very fast.

In agenda view, it's very slow.

The issue is in that function: 

kendo.ui.AgendaView.prototype._tasks

On the 2nd loop, there's that call
task = event.clone();
and this one is repeated for each day of the event, even if the day to analyse is out of the agenda current period.

I think you can solve it by only looping the "visible" days of the current view.

In our case, events have several other fields not related to the agenda.  We are able to increase performance by removing them and only keep required ones, it's better, but still slow.

All others views performs very well with huge dataset / events on multiple days.

Feature in scheduler to display multiple vertical lines at configurable date/times like the below red lines in the screenshot.

We would like to use these lines to make it clear the period between two date/times to the user when viewing the Scheduler.



Styling of the line could be similar to the current time marker.
