InfoPath Dev

How do I access my control properties from the code generated for the button_click event by MVSTA? All I get is the FormCode class with a little automatically generated code from InfoPath and the Event sub. Any help on this would be great Thanks

use Maindatasource,CreateNavigator().selectsinglenode(field x path, namespacemanager)

field x-path can be found by right clicking on field and selecting copy x-path.

Thanks Very helpful
