New Post: Prism-MEF: how to navigate to view in different module using UriQuey

Hi isakavis
Thanks for your effort.

I used following code in ControllerA to navigate to View_B (TestPacksView) and send the parameter
SubsystemNo

 var uriQuery = new UriQuery();
            if (Subsys != null)
            {
                uriQuery.Add("SubsystemNo", Subsys.SubsystemNo);

            }

            var uri = new Uri("TestPacksView" + uriQuery.ToString(), UriKind.Relative);
           
            regionManager.RequestNavigate("TestPackGridRegion", uri);

        }

then i got this ActivationException:


"Activation error occured while trying to get instance of type Object, key "TestPacksView"

i don't know if this is because View_B (TestPacksView) in different module or because the parameter
"SubsystemNo" is not received by the ViewModel_B hence View_B not constructed ...
