window

I have a WPF Window that open a modal child window to load some data. Both window have a own viewmodel, now I have this problem: after I close the child window it seems still running in background!

To close the child window I set DialogResult from viewmodel command; now, if I create a new data and then I edit it from parent window (with the child window closed before), the child window still capture the property changed event for the properties previously bind.

How can avoid this?

I would clear every reference with data when I close modal window. Which is the best practise to do it?
