Typically you will either data bind, or not. In this case I recommend that you bind to an in memory representation (an entity model) which is synchronised with the database, instead of binding directly to the database. (Depending on how complex the data is, you can either construct this object model yourself or use a persistence framework like NHibernate to handle it for you.) Then, on your intermediate entities, you can also have interface related properties that are not bound to the original data source, such as CurrentIcon. These should be what the tree image is bound to. (They should also be dependency properties in WPF, or notify through INotifyPropertyChange in WinForms, so the binding is updated.)

Then, your button can simply do myBusinessEntity.CurrentIcon = whatever and the binding to that property will update the tree view.

Note that I don't have experience data binding the TreeView so please don't ask for details of how to implement that as I don't have them!
