Refresh view is not working

Hello Dennis,
I appreciate your prompt response.
I used this code:
            IObjectSpace os = Application.CreateObjectSpace();
            Sales_Detail sl = os.CreateObject<Sales_Detail>();
            DetailView detailView = Application.CreateDetailView(os, sl);
            detailView.Refresh();
Also this one:
PickingList record = (PickingList)e.CurrentObject;
Session ses = record.Session;
CriteriaOperator criteriaDetail = CriteriaOperator.Parse("[Oid] ==?", detailPick.Part.Oid);
Sales_Detail itemDetail = ses.FindObject<Sales_Detail>(criteriaDetail);
ses.Reload(itemDetail);
None of them are working.
Please advise,
Gary

Gary, I checked your code, but could not find where you used any of the two solutions I suggested above. Take special note that you need to access the Sales_Details ListView (I guess that it is called as SalesHeader_SalesDetails_ListView in your application model).

Hello Dennis,
I am sorry to bother you, but to find the view and refresh is driving me crazy.
What I did:
1.- THIS WILL ACCESS TO THE SALES_HEADER_LISTVIEW
private XafApplication app;
View vc = (app.MainWindow.View);
vc.Refresh();
vc.ObjectSpace.Refresh();
I thought that this will refresh also the Nested Views, but was not working.
2. Then, based on VC, I get the ObjectSpace (in order to get the same Object Space that the Parent VIEW) and access to SALES_DETAIL_LISTVIEW.
IObjectSpace ob1 = vc.ObjectSpace.CreateNestedObjectSpace();
Sales_Detail sl = ob1.CreateObject<Sales_Detail>();
DetailView dsl = Application.CreateDetailView(ob1, sl);
dsl.Refresh();
dsl.ObjectSpace.Refresh();
Also is not working.
Regards,
Gary

I am afraid that neither of the two code blocks you wrote access the nested ListView and refresh it as I suggested earlier. To access a nested ListView, you can either 1) write a ViewController that will target this particular ListView OR 2) Use the DetailView.FindItem method to access the corresponding ListPropertyEditor and its ListView property. Here is some pseudo code for your reference:

C#
((ListPropertyEditor)theContactDetailView.FindItem("Tasks")).ListView.CollectionSource.Reload();  
//OR  
((ListPropertyEditor)theContactDetailView.FindItem("Tasks")).ListView.ObjectSpace.Refresh();  

I hope you find this information helpful.

Hello Dennis,
I have being fighting to apply something that should be reasonable simple as refresh the instance of an object in screen, that, the waste of time and testing your solutions and many of the solution exposed in the devexpress.con, are outside the boundary of a product that looks simple and full of functionality (which is sold as "Focus in the Business Processes instead to a complex programming details"), but weak in something like this refresh.
I have taken the critic from Daniel Ruoss five years ago in which you are also involved, and also have implemented the same Controller class and it doesn't works.

Also the next examples and cases were implemented in my system and nothing looks to work:

As a last try I have added a simplified project and also a PDF document, that explain you how to reproduce the case. Once you run the project 2 Orders with its lines are created in order that you just press the Action [Shipping Parts] and could check why I cannot find the reference to the Sales_Header_Sales_Details_View in any way and also even I subscribe a lot of Events to Sales_Details, or Picking it is not working.
As I hint what I see is that the code in the PickingController is acting as another user in a multi-user application writing the transactions in a different session/object Space, therefore none of the Controller subscribed to the events trigger the Update in the Sales_Details_View.
Finally I would like to remark that in this project I have removed the lines and Controllers that never worked in order to avoid to disturb you with a lot of useless lines and classes.

Hello Gary,
I should say that refreshing data in a View is straightforward in XAF (or at least no more difficult than it is implemented in other frameworks and technologies) and does not require any extra knowledge from developers. As I mentioned in my original answers, you can use either the required ListView's ObjectSpace.Refresh or CollectionSource.Reload methods.
As I wrote in the beginning, it is important to ensure to access the correct ListView object, and not call View.Refresh or View.ObjectSpace.Refresh for unrelated Views as you did.
Above, I also indicated how to ensure that you refresh the correct ListView object:
1. Take special note that you need to access the Sales_Details ListView (I guess that it is called as SalesHeader_SalesDetails_ListView in your application model).

2. If this does not work, then you used a wrong ListView object.
To ensure that this is what you are looking for, please inspect its Id or Caption properties while debugging.
After checking your project, I found out that you have implemented neither of my suggestions and that is the reason why it does not work in your project.
To make a long story short, I have modified your project to demonstrate the solutions I outlined in action. Take special note of the LinkToSalesHeaderFromPickingListController class I implemented and its use in your code. The purpose of this class is to provide a link to the correct ListView object, because your scenario is quite complex, i.e., it involves a chain of unrelated Views (in the simplest case, you could store the correct ListView object in a static variable, or somewhere else).
I hope you find this information helpful.

Hello Dennis,
I found also a Solution last Sunday which is working for me and looks much more simple that you provided.
In the same class ConfirmOrderController.cs and in the same line you added LinkToSalesHeaderFromPickingList
…
DialogController dc = Application.CreateController<DialogController>();
e.ShowViewParameters.Controllers.Add(dc);
e.ShowViewParameters.CreatedView.Closed += CreatedView_Closed; //My Added Line
          }
  }
void CreatedView_Closed(object sender, EventArgs e)
        {
            this.View.ObjectSpace.Refresh();
        }
It works well for my purpose.
Thanks for your support
Gary
