Which treeview control are you using? Have you checked its documentation? (chances are it has expand/contract methods in some form).

The basic rule for this is to store the state of every tree node at the time of refresh (either using url parameters or localStorage concept) and to re-apply those stored values back to the treeview to expand it.

For example,
step 1) webpage opened for the first time (treeview is in collapse form)
step 2) expanding one or more treenodes (also, preseving all those nodes that are expanded)
step 3) browser is refreshed because of some user action / event (passing all the preserved values to the request so as to get it back after refresh or storing the values in cookies or localStorage)

Thanks & regards,
