The TreeView is displayed using the order of the data it's bound to. If you are loading the data from SQL, you can use OrderBy to sort the query - http://www.w3schools.com/sql/sql_orderby.asp

Hello Pia,
You need to call .FindControls on the RadComboBoxItem which holds the TreeView. If you have only 1 Item, than you can directly access it:
cbParameters.Items[0].FindControl("tvParameters");
You probably won't need more than 1 TreeView there - if there are more every single tree can be represented as a subTree of a bigger one.
Also, just to be sure that the item(s) is/are instantiated from your ItemTemplate, place:
cbParameters.DataBind();
before accessing the tree(s).
This will ensure that the tree(s) is/are populated (the searched control(s) exist(s)).
Finally, there is a great article exactly for your case and I recommend you reading it:

Hope this will help you! :)
Kind regards,
