title: Updating another property based on a property, vice versa
body: <p>My issue is I have three properties with mutually dependent in my WPF application. I have implemented InotifyPropertyChanged also for the class. I am not sure how to update second property based on other.</p>
  
  <p><strong>Example:</strong></p>
  
  <p>Properties : ActualValue, ChangedValue, Change</p>
  
  <p>ActualValue is Fixed, and it is possible to update ChangedValue and Change.  That means if I update ChangedValue, the Change is calculated like (ActualValue-ChangedValue) and set.  And when Change updates, the ChangedValue will be calculated based on ActualValue and Change.</p>
