Conditional Overlaps of Appointments?

As a point to add:
The functionality is currently provided through the dayPilotScheduler control and there isn't any reason to change this.

Hope you can help.

Thanks & Regards

You can use the real-time event handlers to implement it:

• EventMovingJavaScript
• EventResizingJavaScript
• TimeRangeSelectingJavaScript

The latest sandbox build (8.3.3582) supports DayPilot.Row.events.forRange(start, end) client-side method that you can use to find existing events in the row.

A quick example for event moving:

<DayPilot:DayPilotScheduler EventMovingJavaScript="moving(args)" ClientObjectName="dp" ... />

<script>
function moving(args) {
  // find events at the target position that block the location
  var events = dp.rows.find(args.resource).events.forRange(args.start, args.end).filter(function(e) { return e.id() !== args.e.id(); });
  if (events.length > 0) {
    args.allowed = false;  // block this location
  }
}
</script>

The filter() call above only removes the source event from the array. You'll need to modify the condition to also remove other events that don't block the target location.

You need to turn off the built-in overlap prevention feature (remove AllowEventOverlap="false").

Dan and Team,

Thanks for replying, both by e-mail and on the forum...
I will investigate further to see if your suggestion helps my situation.

I'll leave the call open pending the results of my investigations.

Thanks
