I have a timer which refreshes the browser every 30 seconds. If I try to drag a task from Radgrid to RadScheduler, at that point if the timer refreshes the browser the task freezes/getting stuck somewhere. (Please see screenshot). It is disappearing when I hit F5.

How can I fix this issue?

Thanks in advance

      

Hello,

It seems that refreshing the page before the dragged task is not being dropped yet causes a JavaScript error that freezes the page. I would recommend to stop the timer while user is dragging the current task and start it again once the user drops that task on the RadScheduler control.
In this form thread you may find a very similar scenario and a sample project that demonstrates the mentioned approach.
