[Solved] RadGridView - Master/Detail - WCF Data Service

[Nuno]

Hi,

I'm trying to have a Master/Detail association on a RadGridView, but i'm having problems in getting the detail values when the user expands the row.

The data comes from two tables ( [Artigo].ID == [ArtigoArmazem].ArtigoID) on an ADO.NET Entity Data Model, and i'm using a WCF Data Service ( referenced as a service reference on the client).

I'm filling the first radgridview with

        private void BeginRequest()
        {
            DataServiceQuery<Artigo> query = dbContext.CreateQuery<Artigo>("Artigo");
            query.BeginExecute(RequestCompleted, query);
        }

        private void RequestCompleted(IAsyncResult asyncResult)
        {
            DataServiceQuery<Artigo> query = asyncResult.AsyncState as DataServiceQuery<Artigo>;
            
            var artigos = query.EndExecute(asyncResult).ToList();
            this.radGridView.ItemsSource = artigos;
        }


I've read some of your examples but i'm not being able to  show the data from the second table on RowDetails when user selects a row.


Can you please help?

Thanks
