New Post: How do I implement the logic to navigate once the service result is returned

I see. I will use this interface to notify me when the async operation is completed. But, since I am performing the operation on View1.ViewModel and displaying the result (collection of a type) on View2.View, how would I be able to retrieve the result on View2?

I can only send a query string to View 2. And, in this case since I will send the query string to the async operation, I don't have to send any query string to View2.

I am guessing, I need to create an ObservableCollection of the type. On View1.ViewModel I load this collection; on View2.View I display it. Is this correct?
