Hi ,

I am using Silverlight with telerik ORM.
Im my Sql database i have 2 tables

Table1(For combobox)
Id Name Description

Table 2
Id1 Name1 Id(of Table 1) Description

using the dataservice wizard i have created the service class to these tables in Telerik ORM

No i need to populate my radGrid view with data from Table2 and the data from Table1 should come as a combobox in the Id(of Table1)
column

My code is as follows but i am unable to display the required out put.

ObservableCollection<Table2> tc = new ObservableCollection<Table2>();

            DataServiceQuery<Table2> query1 = this.dataManagaer.Table2s;
            query1.BeginExecute(
               (IAsyncResult result) => EntitiesLoaded<Table2>(result, tc),
               query1);


            ObservableCollection<Table1> bm = new ObservableCollection<Table1>();

            DataServiceQuery<Table1> query2 = this.dataManagaer.Table2s;
            query1.BeginExecute(
              (IAsyncResult result) => EntitiesLoaded<Table2>(result, bm),
              query1);

            GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn();
            comboColumn.Header = " ID & Name";
            comboColumn.DataMemberBinding = new Binding("Id(of Table1)");
            comboColumn.SelectedValueMemberPath = "Id";
            comboColumn.DisplayMemberPath = "Name";
            comboColumn.ItemsSource = bm;
            comboColumn.ItemTemplate = this.Resources["ComboItemTemplate"] as DataTemplate;
            radGridView2.Columns.Add(comboColumn);


            radGridView2.ItemsSource = tc;

Please could some suggest how this can be done.

Regards,
Ron
