Treeview Control that Populates reports from Report Server by username

SSRS 2012 Tree-view Component with Report Viewer Control in VB Asp.net I would like to have the following developed. Certain SSRS Reports have been assigned to users on the report server. what i need is to have a treeview created that populates all the reports from the report server for that specific user by showing a folder and the relevant reports under it. If the specified user selects a report from the treeview, it must be displayed in a report viewer control that is located right of the treeview component in the same frame. i also need logic to pass the username from the login screen as a variable so that the treeview reflects the correct [login to view URL] the user logs in, the first report to be viewed is the dashboard report (this report resides on the server)
