Column Filtering

Asked by Sven Heuer

Hi, is there a way to filter "empty" columns like it is possible for the schedular.

I am looking for something like this:

onColumnFilter (args) {
  var roomIsOccupied = (!args.events.isEmpty());
  args.visible =  roomIsOccupied);
}

Currently I have a "checkbox room list" and I can enable/disable a room. But if I filter a calendar, i want only see these rooms, which a "accouppied" by the filter.

how-to javascript

In the latest sandbox build (2023.2.5562 - see https://release.daypilot.org/changes/js/), the args.column property now holds a DayPilot.Column object (https://api.daypilot.org/daypilot-column-class/) which you can use to find the related events and also check if the column is empty:

onColumnFilter (args) {
  var roomIsOccupied = !args.column.events.isEmpty();
  args.visible = roomIsOccupied);
}

Hi Dan,

I tried its but got a "Uncaught TypeError: e.events is undefined"

onColumnFilter (args) {
  var roomIsOccupied = !args.column.events.isEmpty();
  args.visible =  roomIsOccupied;
}

Missed I something obviously?

Hi Sven,

There was a problem with the implementation - but it should be fixed now in the latest sandbox build (2023.2.5566). Please let me know if the problem persists.
