ASP.NET treeview performance issue with IE7,8

Question

I am using treeview in my asp.net application which have 2000 nodes in it. The treeview takes 40 sec to load on IE7,8 while same page takes 1/10th time on Firefox and chrome. Is there any solution to this problem. Tried searching for this but found only unanswered questions. If this is a limitation of IE 7,8 then what is the reason for it. Is it because of the rendering engine. Is there any solution to the problem ? I mean i tried using the jquery treeview but again it hangs the IE and alert popups up for slow script.

Please help.

Answer 1

Have you tried this jQuery plugin? http://www.jstree.com/

It supports AJAX loading, which is great for a 2000 node tree.

Answer 2

When you open the rendered html generated from the tree view, you will find that the control generate a hell of html table, tr and td which I think is taking a very long time to be rendered on IE so I suggest that you create a new custom web control that inhertis from the treeview control and update the "Render Method" to write Div's instead of HTML and this will require a professional developer and HTML designer to do this.

I think you can after that share this new control with the community and we can enhance on it with you to get rid of this dummy asp.net gridview.
