Can't get Heirarchal data to show up

[Chris]

Hi,

I have a situation where I have successfully shown data in a ParentGrid, but now I have setup a child grid but cant get it to display data.

XAML:

 <telerik:RadGridView Name="CustomersGrid" ShowInsertRow="True" Grid.Column="0" SelectionChanged="CustomersGrid_SelectionChanged">
            <telerik:RadGridView.ChildTableDefinitions>
                <telerik:GridViewTableDefinition/>
            </telerik:RadGridView.ChildTableDefinitions>            
            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerik:RadGridView Name="ChildGrid" ShowInsertRow="True" Loaded="ChildGrid_Loaded" />
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>
        </telerik:RadGridView>


C#:

 public MainWindow()
        {
            InitializeComponent();
            var customers = Repo.GetCustomers();
            CustomersGrid.RowIsExpandedChanging += CustomersGrid_RowIsExpandedChanging;
            CustomersGrid.ItemsSource = customers;
            
            DataContext = this;
        }

This works fine and shows the child grid when clicking on the + sign. The ParentGrid is bound to Customers (Select * FROM Customers) I need to know how to bind the child grids to Agreements (Select * From Agreements where CUST_NO = '" + CUST_NO + "'"). I cant seem to access the Child Grid's itemsource to set the data binding.

What am I doing wrong?

Thank you very much!
Ron

Hi,

I would advise you to move the data loading logic into your view model and expose the result as a new property. Then you would be able to bind the ItemsSource to it.
