html5 scheduler event multi selecting

The Scheduler component supports selecting multiple events.

  • Individual events can be selected or deselected using Ctrl+click (enabled by default, requires eventClickHandling="Select").

  • Multiple events can be selected using Shift+mouse drag using a multi-select rectangle (needs to be enabled using multiSelectRectangle property).

  • You can select multiple items programmatically using the selection API (multiselect.add() method).

Multi-Select Rectangle

To select multiple events using drag and drop (rectangle), use the multiSelectRectangle property:

The Scheduler supports the following rectangle selection modes:

  • "Disabled" (default)

  • "Free" (free-hand range)

  • "Row" (select events in a single row)

Free-Hand Rectangle Selecting

Enable free-hand rectangle selecting:

Real-time event handler:

dp.onRectangleEventSelecting = function(args) {
  var msg = { return item.text(); }).join(" ");

Start selecting on event click:

dp.onEventClick = function(args) {

Append the events to the existing selection:

dp.onRectangleEventSelect = function(args) {
  args.append = true;
