TreeView Search Node

Question

I've a large treeview.(some 20 root nodes, each one has some more than 50 childs, sub childs etc).

This tree is populated from sql server 2005 database.

I want to highlight the searched nodes. How can i do this?

 For Example: if i search a text '%SD Tools', all the nodes having text '%SD Tools' should be  
 highlighted With Red Color And My Curser Current Postion Should Be On Searched Node
