Hello, If i reset a controls DataContext (say to a List<MyClass> of MyClass objects) would i thereby remove the UI reference to the data source? And thus permitting the objects of the datasource (a list loaded from an xml file) to be garbage collected. My problem is that the UI seems not to release references to large list datasources (loaded from files) and so things are not garbage collected, and the memory footprint grows, eventually grinding the app to a halt. This is a resonably generic problem, of how to administer UI references to data, and have these references released when no longer needed. As an alternative to databinding i could populate the rows of my listview or listbox manually. I cant see apriori the advantage to this as far as removing UI references to my datasource goes. I would garbage collect just to test whatever technique (implicit or explicit) i use to remove UI references to my datasource. reagards, paul |
