I'm creating a load on demand treeview and using multiskin mechanism .
and every node on the tree has a forecolor and i need to load it dynamic with the node expand but i can't every time with any post back the tree take the skin default color ,i tried to save the datasource to the viewstate and every time in post back i set the colors again but the load on demand don't work then,it seams that the viewstate been locked 

please advise  

i solved the issue by using the session instead of the viewstate
