backward forward arrow event

Is there an event available for backward/forward arrow buttons (next to Today’s button). I need to capture date range changing by that button

There is no separate event, if necessary you can override related onclick handlers.

Also, you can try to use onViewChange event, and check from it

scheduler._min_date
scheduler._max_date

to get current visible range

how can i write click handler for those backward/forward arrow buttons?

scheduler._click.dhx_cal_prev_button = function(){ ... } scheduler._click.dhx_cal_next_button = function(){ ... }

Now how can i set the min max range of scheduler through that click event?

It can be handled in better way.
