I m trying to drag and drop event from external source into the calendar and trigger some functionality. This is working for day, week and month modes but when i try to drop into timeline mode, onDragDrop event is getting trigger but
timeline is a built-in scheduler's timeAxis, it has own event resolving methods. Better to share your solution if you want we fix it, but in general you can have a look at scheduler's drag-from-grid demo for code example: https://bryntum.com/examples/scheduler/dragfromgrid/
I checked it deeply. That's not supported right now, unfortunately. Calendar's and Scheduler's (timeline) drag-n-drop are not compatible. I've opened a feature request to implement that. https://github.com/bryntum/support/issues/4682
