Asp.net web application
I have one div (div is scrollable), inside this div there is a treeview.
I want to scroll selected treeview node into middle of div.

By using selectednode.scrollintoview(true), I am able to scroll selected node on top of div.
but my requirement is to scroll/show that node in middle of div.

div.scrolltop = (div.scrollheight - div.clientheight) * 0.5
this line of code, scrolls the div into middle, but i want to scroll selected node into middle.

Kindly help me out ASAP.
I am struggling with this since 3 days.

Solution 1

You should apply the scrolling where you do the div.scrolltop to the treeview control instead.
Once you do the selectednode.scrollintoview(true) call, you follow that up by offsetting the scrollposition of the treeview to add half the height of the parent div.
