Scroll by entire row

Is it possible to set up dhtmlx grid to scroll by a predetermined number of pixels ? Or to setup scroller in such a way so that when you click on up/down buttons grid will scroll up/down by exactly 1 row ?

There is no such built in functionality. The scrollbar is a native browser control and works without “align to row” behavior.
Basically it possible to catch the onScroll event and made some correction to scrolling state

mygrid.attachEvent(“onScroll”,function(x,y){
    window.setTimeout(function(){
       mygrid.objBox.scrollTop=Math.round(y/20)*20; //align to row
    },1);
});
