A screenshot how the result looks would help to quickly find out if this sample is what someone is looking for.

Hi,

I have added an image showing how the application works. Thank you for your idea.

I am attempting a similar solution but the layout view (lvPictures) is itself a detail view (of gvLocation) and I want the detail grid view displayed in the PopupContainerControl to be a view (gvPicTags) I've created in the grid designer that itself uses editors created in the grid designer's In Place Editor Repository to add/update/delete records in gvPicTags.  Is this possible?

I've implemented the solution posted here to display the detail grid but doesn't appear to be picking up the grid layout (gvPicTags) I've created.  It does however display the raw data correctly...

Funny, sometimes writing a question helps clarify the solution...

In the lvPictures_GotFocus I execute:

       helper = New MasterDetailHelper(layoutView1, ViewType.Grid, gvPicTags)
       helper.CreateDetail()

LayoutView1 is the sender object (lvPictures) and I added an additional parameter referencing the detail grid view (gvPicTags) which I created in the designer.  In CreateView() I changed the detailView_Renamed assignment for GridView from New GridView(DetailGrid) to the detailGridView (gvPicTags) which I passed via the new parameter.

There is a file in this example called Database.mdf that requires SQL Server version 661. My server only supports 655. Can you please provide instructions or more files so that I can run this example?

Hi devexpress,
Thanks for the sample, but it doesn't work with EF 6. I tried using ((IObjectContextAdapter)my_context).ObjectContext in order to convert it to ObjectContext, but without success.
Any help please?

I have extracted your question into a separate ticket - T237245. Let's continue our discussion there.

Hi Ivan,
It seems the ticket T237245 is a private one. Please make it public.

Hi Mikhail,
I have decided to create a new public ticket on your behalf and post the solution there - How to upgrade E3863 to make it work with EF6. Please refer to it for more information.

I will also be interested to see the new ticket "How to upgrade E3863 to make it work with EF6".

Is there any plan to make that Behavior part of your MVVM framework?

Hi Pierre,
We don't have immediate plans to add this class to our MVVM framework.
I have marked the T237435: How to upgrade E3863 to make it work with EF6 ticket public. Please refer to it.

Question Comments

How come the view should be responsible of creating documents and panels? In a true MVVM design this should be the ViewModel's responsibility.

Is anyone from DevExpress monitoring comments on examples?

Hello David,
The View only creates root containers where dock panels are placed. This is a required step of creating the Docking UI.

Alex, I was refering to MainWindow.xaml.cs file. It has AddPanel_Click and AddDocument_Click methods, in which view models instances are created.

If the purpose of the example is to demonstrate how DX docking can be used with the MVVM pattern, then the DockLayoutManagerViewModel class should be responsible for creating / adding documents. Giving this responsibility to the view class goes straight against MVVM design rules, IMHO.

David, you're right. We have moved the code that creates Panels and Documents to View Models.

Thanks. You might want to clean up MainPage's code too. The DockLayoutManagerViewModel is instanciated in both the XAML and code behind. ;)

Can this example extended to using PRISM regions? or is there an example already with this feature utilizing Prism?

Hi, I need a dock UI with ability to host different types of views in Document Group (Tabs) at run time using Prism. Can you point me to an example of it ?

Hello Raju and Gagan,

We accidentally discovered that your initial posts were out of scope of our Support Center for a long time. Please accept our sincere apologies for not responding in a timely manner.

We have few samples showing of how to use the DXDocking suite with the Prism framework. Below is a list of them. Please take a moment to review them and let us know if you have additional questions.

Hi,

Just upgraded to 13.1.5, and this no longer compiles. Quite a few undocumented things looked to have changed.
Can we have a 13.4/5 version that works please?

Thanks.

It seems many problem, can this function to be support in new version ?

Hi Justin,

We cannot guarantee that this functionality will be available in the latest version. For now, you can try to extend this example manually. If you face difficulties doing this, do not hesitate to contact us.

Hi Alex,

how to implement this custom editor with MVVM?
Thanks, Viktor

This probably does the trick for standalone lookup editors, but I have doubts about using this inside a grid. If my understanding of both the code below and the grid's mechanics is correct, a query will be issued for each and every cell for which such an editor is present. Therefore, if you have 20 records on screen with five columns each having such an editor, that's a hundred of connections opening, querying and closing right there. And EVEN with just ONE column, it will still be under-performing when it will be sorted, grouped or filtered. Even for the non-virtualized rows.

This needs a proper solution. Urgently.

David, you are correct. The editor we implemented in this example is not designed to be used inside GridControl. With the current implementation, a new source/context will be created for each visible grid cell. Please refer to my comment in the LookUpEdit - server mode support ticket, where I clarified our plans regarding this feature.

Question Comments

FYI on this part "If you are using an XAF client, then in the simplest case, you can just set the XafApplication.ConnectionString to the address of your data store service (http://localhost:55777/Service1.svc). "

Literally do this:
WebApplication.Instance.ConnectionString = "http://localhost:55777/Service1.svc";

XpoDefault.DataLayer = XpoDefault.GetDataLayer("http://localhost:55777/Service1.svc",
           AutoCreateOption.DatabaseAndSchema);

           XpoDefault.Session = null;

           using (UnitOfWork uow = new UnitOfWork())
           {
           }

I got the  "Entity is too large"- execption even after I did the fix provided.  Adding behaviorConfiguration="WcfService1.Service1Behavior" attribute to the service node fixed the problem.

Hi,
I am trying to implement a drag select option for columns. something similar to what is already implemented for rows.
i.e. when the user drags across the column header I would like the grid to select all rows for the dragged columns.

I used the following code so far, but is not quite what I am looking for, it only works when a column header is clicked. I would like to be able to drag and select multiple columns.

   Private Sub gridView1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles gvJob.MouseDown
       Dim view As GridView = TryCast(sender, GridView)
       Dim hi As GridHitInfo = view.CalcHitInfo(New Point(e.X, e.Y))
       If hi.InColumn Then
           SelectCells(view, hi.Column)
       End If
   End Sub
   Private Sub SelectCells(ByVal view As GridView, ByVal column As GridColumn)
       For i As Integer = 0 To column.View.RowCount - 1
           view.SelectCell(i, column)
       Next i
   End Sub

Here is a short video of what I am looking for http://screencast.com/t/pAqDpiYPqt

So what are the design time bindings for controls set to in the report?

Hi Support Team,
I've just downloaded Example and I see error in the XtraReport1.cs tab saying

"Could not find type 'Reports.Data'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built using settings for your current platform or Any CPU. "

Unfortunately there is no ability to attach print screen.
What can I do to fix it?

Thanks!

Hello!

I have a dataset with several objects.
If I want a list of several different objects with only one datasource, how can I do that?

Missing design time objects in xtrareport1.cs

To process your recent post more efficiently, I created a separate ticket on your behalf: T131788: E1936 - Missing design time objects . This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.

Sorry, I see that the missing source code is in the Example Runner download.  It is only missing from the web viewable portion (such as definition for InitializeComponent()) which is in XtraReport1.designer.cs I'm guessing which isn't in the web viewable version.

I run this example in my 14.1 environment and it works fine.  If I swap out the Report Viewer for the ASPxDocumentViewer, I get the old "Object reference not set...."
Is there an example that uses ASPxDocumentViewer?  
I saw in this link: http://www.devexpress.com/Support/Center/Question/Details/T119505
That it's 'NOT' good to store the Xtrareport in a session variable, that it is too complex.  Is it more complex with the Doc Viewer instead of Report Viewer?

Please provide the Example in MVC for the same purpose.

Question Comments

Let me give you "some reasons" why this isn't such a specific scenario.
 - accountant company doing accounting for several different companies (it's business requirement that data for each company is in separate database)
 - building maintenance company - again - business requirements demands each building to live in separate database (because of financial data)
 - document managment companies doing document management for multiple companies - again, each company must live in seperate database
 - local community combined with utility company - same people do both things and want to keep things separated

If you like, I can go on. No, you can't go to this companies / communities and say "But, it's better if we put all this to one database" because they will reply "Thank you, we'll find someone who can do it with multiple databases".
The point is, there are many reason why one piece of software should be connecting to multiple databases, so it's not such a specific scenario really. It would be nice to have this functionality out of the box instead of implementing this hard to understand piece of code.
Also, since application is distributed to many different clients, it would be nice that end-user could setup application on first startup (add/create required databases with connection info).

This example doesn't work.
Go to WinChangeDatabaseController.cs and set breakpoint in changeDatabaseAction_Execute. This code never executes since created SingleChoiceAction is not visible on logon form, instead some default editor is created with PredefinedValues and it's behaviour is not modified.
Can you fix this code please?

@Mario: I have answered you in www.devexpress.com/issue=Q484359
This example worked correctly in my tests. In any event, I have just updated it to .NET Framework 4.0, just for more convenience.

Thanks Dennis. I understand now how this works.

Hi Dennis, each time i try to logon i keep on getting this error: "Make sure your user name is correct and retype the password in the correct case." What do you suggest?

Hi,

Great piece of code !

I noticed a weakness. In Web/Win controllers, preselection of correct item is done via following code :
if (Application.ConnectionString.Contains((string)item.Data))

This fails in case database name's string is contains elsewhere in ConnectionString. It also fails in case we have multiple databases with names containing each other, for example "customers" and "customers_geneva".

We should store the current database name in a static property somewhere and make a strong comparison.

Hi Dennis,

From the code below,

public const string Databases = "ChangeDatabase_DB1;ChangeDatabase_DB2";

Is there anyway I can pass a dynamic attribute value? I know this attribute requires a fixed value in compile time, but I don't think it is practical to put the database name or maybe a server address in a hard coded way. For example, it would be very practical if we can read this value from the app.config file, and pass it to the ModelDefault attribute.
