I am doing hiearchical binding to the xamTree and successfully populate the tree to multiple levels.

My question is around binding to the checkboxes.  I have read that I can bind to a property in my source tables however whether checked or not varies by user.  So, for example, I have a number of hiearchical tables that populate the tree, but I need to bind the checked value based on a different table (queried by user to determine what is checked).

Can anyone give me some guidance on best practices to implement this?  I could implement a model which rolls this data up into one hiearchical view, but if theire is an easier way to do it I would prefer...

Thanks!
