i've recently encounter problem while working with radtreeview:
i've radtreeview with datasource (datatable) from database however when i click button i want to change that datasource
(rebuild radtreeview) and load radtreeview with new nodes and roots; data from database are proper but assigning it to radtreeview
doesn't work - old "state" radtreeview remains.
is there any way to do this ?
