title: asp.net tree css adapter selectedNode is null?
body: <p>I just switched to using the CSS Adapters for my TreeView control on one my ASPX pages.  Now, for some reason, I cannot use the SelectedNode method except in my OnClick() event.  ALL other events show that the SelectedNode is NULL.  I am currently using a bunch of non-visible labels to store tree info everytime someone clicks on a node.  Very, very, very wrong way to use this control.  What is the secret to getting the control in code behind when CSS Adapters are enabled?</p>
