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.
