When setting the datasource of a treeview to a SiteMapProvider, it automatically renders the Title as text wrapped with an HRef with the Url of the SiteMapNode, which is perfect for navigation purposes.
But I am currently trying to make a usercontrol to allow a WebAdmin to update the sitemap dynamically via screen versus web.config, or db table.
In order to manipulate this tree, I wish to find the SelectedNode.
But I am unable to set it via screen clicks, as the tree node's text is rendered as a HRef -- which means that instead of clicking and setting the SelectedNode, I ...Can a node have two parent nodes in treeview control ?

My asp.net app has 2 div columns. On the left div column I have a treeview control.
