>The issue is that in WPF I need to set the correct DataContext or Set the Grids ItemsSource each time an EntityList is retrieved (Parent, childs). So I want to set it by a simple code after the data is retrieved. Note that child object can be retrieved from the HookParentRetrieved.

OK, I am not sure I have much help with WPF. In web and windows stuff the controls subscribe to data retrieval events and resond on their own. WPF is different in this respect and I don't have the answers.

Have you read all the information on WPF in the Deve guide?
