Hi, we're using scheduler and we have the selectable set to true so users can drag and select timeslots to create.

The issue we're having is related to the autoscrolling when the user attempts to create a selection that is longer than the display window and attempts to drag past the display window but the scheduler would not auto scroll to expand the selection.

However, if we were to expand an existing event, the handler would be able to expand past the display window and scheduler would auto scroll. We were wondering if the event creation could have the same behavior.

 

Thanks,

Kenneth

We have a need to be able to provide a dropdown above the scheduler, in order to allow the end user to change the time zone of the scheduler dynamically, even after it has been initialized.  Our team was disappointed that this is currently not possible (http://www.telerik.com/forums/timezone-dropdown), but maybe in the future.  Thanks for reading.

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.
