I'm trying to preventing the creation or updating of a task with the same route_id and the same period of a another task.
Here is my code : http://dojo.telerik.com/@idoglik6/ocavO
I'm using a function called : isRouteAlreadyScheduledInside() to find out if the user can continue with the save process or not.
if not the flag "sameRouteLocation" is on and the tooltip pop up.
My problem is that: It's not working so well and the tooltip icon pop up with delay.
I would be happy to use the build-in tooltip "k-tooltip-validation" with my condition (isRouteAlreadyScheduledInside) on my select called "Route".
