Hi, I would need torefresh the grid size on every page resize and I am looking for the best practice to do it.... If it is possible to do it on client side it would be great. Thank you for your time.

<script type="text/javascript">
        window.onresize = DoSomething;

        function DoSomething() {
           
        }
    </script>

Do anything you want in "DoSomething" event PerformCallBack and resize your Grid.

So this means we  cannot dot it on client side alone? From what I understand we are forced to do a callback if we need to adjust the scroll-height property of the gridView.

on client side only
