i have a treeview that is bound to sql table.and in the right hand side of my treeview i have two buttons ,one for move the nodes upper,and the other is to move them down.and it works perfectly.but i want to save the position of the nodes . for example when i move the node up ,i want that to be saved in my table,so that the next time i open the webpage, the appearance of the nodes be the same as when i closed my page.i mean when users make changes,it should be saved .
