When I move event that is on the very left hand side of timeline further to the left, it's start time is decreased. Can we block this?
For example dragging the "1" event to the left here http://dojo.telerik.com/IMeXa will set start time to an earlier than 7am.

Hi Pawel,

This is the expected behavior, however it could be prevented by subscribing to the Scheduler's moveEnd event. Here is an example showing how to check the View's start time and the time to which the event was dragged and prevent the movement if the conditions are not met.
