Rad Combo box with Rad Tree view

[mani]

Hi
          I used the user control, the user control functions like combo box with rad tree view. this user control i used so many pages. I used the sessions for selected rad tree view selected nodes for searching or inserting values. it is working fine.When i select(node rad tree view) and search. the result found.  when i move to another page search by default this session value search result is showing. Herewith i cannot clear the session value after search because the need data source asking session value for  Edit and retrieval purpose. Let me how can i solved this problem..

Herewith i send some sample coding
