Thanks for your great help. The issue with my code is below:
To open a dialog:
unction openDialog(){
$('#perDialog').dialog({
title: 'All Students',
width: 900,
height: 650,
closed: false,
maximizable:true,
cache: false,
href: 'Students/All'
}
href:Students/All
<table class="easyui-datagrid" url="Lists/getclassdata" singleSelect="true" rowNumbers="true" striped="true" showPageList="true" data-options="view:bufferview, pageSize:50, autoRowHeight:false,">
//other codes........
</table>
With clicking and dragging the vertical scroll bar, it is ok. But using the mousewheel hardly scrolls.
Thanks and regards
Alfred
