Hi,
Sorry but after reading the documentation and looking at the demo, I did not see how to populate the child grid. I certainly missed a point somewhere.
I've read this one : http://www.telerik.com/help/silverlight/gridview-basic-hierarchies.html
I have 2 seperate collections of data with a relation. Ok I did set the hierarchy as described in the documentation and I can see that the grid acts like expected. I see the parent data but of course since I don't know where to put my second collection I see nothing when I press the + button. Where's the second ItemsSource, How do I access the second grid ?
The grid have my first collection of data in the ItemsSource and the grid is ready for hierarchy. All I need now is to populate the child grid. Thank you for any hints

By the way, I have 2 collections of DataContract object that comes from WCF call
I also tried this code which have a collection of Application inside my Customer Object which I populate
I still don't see the data in the child grid
I can see that everything is tehre in place which is each Customer object having it's own collection of Applications
I also tried this code which have a collection of Application inside my Customer Object which I populate
foreach
(GAM_Customer Customer
in
_Customers)
Customer.Applications =
new
ObservableCollection<GAM_Application>(_Applications.Where<GAM_Application>(a => a.CustomerId == Customer.CustomerId).ToList());
I still don't see the data in the child grid
I can see that everything is tehre in place which is each Customer object having it's own collection of Applications

The code for the relation is here :
rgvCustomers.ChildTableDefinitions.Clear();
GridViewTableDefinition gtd =
new
GridViewTableDefinition() { Relation =
new
Telerik.Windows.Data.PropertyRelation(
"CustomerId"
) };
rgvCustomers.ChildTableDefinitions.Add(gtd);

Hello Marc Roussel,
Maya

I am sending you a sample project illustrating one possible way for defining Hierarchy Grids and setting their ItemsSource-s, using WCF RIA Services.
Let me know if it helps and corresponds to your requirements.

Sorry, there's nothing fonctional for me in there as I'm using just PURE WCF call,
[DataContract]
public class Customer
{
}
and
[DataMember]
Properties
{
}
A class which comes from a simple WCF call.
Here's an example of it :
When back from the GetCustomer and GetApplication , I populate my collections and this is done for 2 separate collection with a relation between them
The class above is just an example of the object coming by from the Async call to the WCF service .svc. There's no mention of Domain in there. It's a pure call, nothing fency !

Hello Marc Roussel,
Basically, the reason for the exception is not caused by the RadGridView and you may use the project for a reference on the approach for setting the ItemsSource of the grids. However, the error you are getting may be due to the fact the .Web project is not the Start-up one.

Let say I have 2 collections of object
with a key relation in each different object
how would you populate the grid in a hierarchy way ?
Also, if it's about adding a collection of application in each distinct Customer, that is something I already tried and nothing seems to appear on the chiuld grid
Collection 1
Customer1.CustomerId
Collection2
Application1.CustomerId
Application2.CustomerId
Customer2.CustomerId
Collection2
Application3.CustomerId
Application4.CustomerId
Customer3.CustomerId
Colleciton2
Application5.CustomerId
Application6.CustomerId

The Project.Web is really the one as startup and the .aspx is the page as startup
however it doesn't work. I tried to read everywhere where I have to take some code example in there that reflect what I need and I do not seem to figure out

I already tried the collection of application INSIDE each customer and as I already mentioned, this was giviming only a blank child grid
I will give you a repro project so we can work out this in the repro
