Hi,

You will need to handle the TreeView's ClientSideOnItemMouseOver, it will be something like this:

Code: HTML/ASPX 
<eo:TreeView ClientSideOnItemMouseOver="mouse_over_handler" ....>
....
</eo:TreeView>


Code: JavaScript 
function mouse_over_handler(e, info)
{
    var treeNode = info.getItem();
    treeNode.setExpanded(true);
}


Thanks
