This following works better if you need to scroll to an arbitrary item in the list (rather than always to the bottom):

function scrollIntoView(element, container) {
  var containerTop = $(container).scrollTop(); 
  var containerBottom = containerTop + $(container).height(); 
  var elemTop = element.offsetTop;
  var elemBottom = elemTop + $(element).height(); 
  if (elemTop < containerTop) {
    $(container).scrollTop(elemTop);
  } else if (elemBottom > containerBottom) {
    $(container).scrollTop(elemBottom - $(container).height());
  }
}

Please keep in mind that all versions of Ignite UI prior to version 16.2 are no longer eligible for support. More information about our products lifecycle is available here.

I created a sample for you (using version 19.1) with a similar grid configuration as the one, described by you, and the issue is not reproducing itself.  Please have a look at that sample and test it on your side. If this is not accurate demonstration of what you are trying to achieve please feel free to modify it and send it back to me for further investigation along with steps to reproduce.

Please let me know if you need any further assistance
