I use a treeview to display paths.
When user clicks a button, the treeview displays other paths from another datasource.
After that, the user can go back to the previous treeview, but if I reload it, the treeview is the same as first load : I mean the selected and expanded nodes are not the same as the user defined them previously.
That's why I want to know if it's possible to save the viewstate before the user changes my treeview and to reload this viewstate after I rebuilt the treeview.
Hope it's clear.
Thanks in advance for your answers.
