I want change the scroll height from clientside. I have seen your examples But my scenario is is different. I have radgrid on popup window with addnotes tab. By defalut grid scroll height is 220px. when i click addnote button i want decrease the scrollheight size to 120px. How to do it. I tried your code but i am getting error like "Microsoft JScript runtime error: 'GridDataDiv' is null or not an object". Here is my code....

function showAddNotes(sender, args) {

document.getElementById('trAddNewNotes').style.display = "block";

document.getElementById('ctl00_PagePlaceholder_winBlkTskAssign_C_tabTskAssign_TabNotes_trNotes').style.display = "none";

var scrollArea = sender.GridDataDiv;

var parent = $get("div1");

var gridHeader = sender.GridHeaderDiv;

scrollArea.style.height = "120px";

return false;

}

<div id="div1" style="width: 100%; overflow: auto; overflow-x: hidden">

<table class="customFont" width="98.5%">

<tr id="tr1" runat="server">

<td align="right">
