The solution is:

  • When an element gets Unloaded from the UI tree, detect properties with a binding expression and reset all the values stored in the DP.
  • Once element is added to the UI tree again (Loaded), then evaluate those expressions again to restore the effective value.

When property is not using bindings, at least we should show a warning indicating the possible memory leaks and what property is causing it.
