title: Loading parent user control form dynamically from child usercontrol datagrid row click
body: <p>I am using mvvm model for my WPF application.</p>
  
  <p>i have a 2 usercontrols in the form
  1. Parent ( form with controls)
  2. Child ( child has a datagrid to show list of rows which are added from parent form)</p>
  
  <p>but the parent form is dynamic. means controls are not static.
  For editing if user click on datagrid row in child i need to reload the relevant parent form dynamically.</p>
  
  <p>how to achieve this using MVVM pattern. Both controls have their own view models.
  please suggest a solution.</p>
