Solution 1

You will need to write treeview state in a temporaray file or the database and retrieve these values when the form / program is loaded again.

Solution 2

That's simple to save it's state, Just follow tha way HERE[^], Once you have stored state in Dictionary object then store that object permanantly using Serialization[^], Once page is loaded again, DeSerialize object back and Load tree view again from it.
