Treeview

I would like to build a asp page to display some data in a treeview which can expand on demand without posting everytime. Thats the easy part! The problem is when I need to refresh the page to get more data or view changes in the "titles". If i expand some nodes and then refresh the page then i need to expand them once again to view the changes. Does anyone have a clever script to accomplish this?

Ok, I have my own, and I use this technique. I have two frames, The left one with the tree view, and the right one with the contens of the selectd tree item. When I expand anything in the left window i pass the value to a right page variable, so I always have a track of the expanded left window nodes. When I reload the left page i ask the right page for the expanded nodes and expand them.
I hope it helps you.
My script is made ussing ASP to retrieve database values, Javascript for the logic and DHTML for hidind showing nodes.

I guess thats the way to do it. It feels like I have tried everything else. I think i need to keep track of the nodes they close to, but i have an idea to accomplish this to.
