ASP.NET 2.0 - keep selection in TreeView(repost)

I have a master page containing a TreeView which is populated from a SiteMapDataSource.

When I expand a node in the TreeView and click a selection under the node then the TreeView gets reloaded and collapsed so I have to expand the node again to see which selection I clicked.

I want to keep the node expanded after a reload if the user has expanded it.
