Question

I have a Datagrid and inside it’s row details template I have another Datagrid

<DataGrid Name="dataGridWorkOrders" ItemsSource="{StaticResource workorders}" >
<DataGrid.RowDetailsTemplate>
  <DataTemplate>
        <Border BorderThickness="0" Background="BlanchedAlmond" Padding="10">
        <DataGrid IsReadOnly="True" AutoGenerateColumns="False" ItemsSource="{Element=dataGridWorkOrders,path=selectedItem}">
  </DataGrid>
 </Border>

Workorders Collection is like:

class WorkOrders : ObservableCollection<WorkOrder>
    {
        public WorkOrders()
        {
            var orderList = OrderDetailsProvider.GetOrders() as List<WorkOrder>;

            orderList.ForEach(
                        order => this.Add(order));
        }

The WorkorderClass has following fields exposed as proporties.

 private string orderID;
 private int totalQuantity;
 private string status;
 private ObservableCollection<Schedule> scheduleCollection;

Now in my second datagrid I want to bind to ScheduleCollection of the currently selected datagrid

Answer 1

The data context of the RowDetailsTemplate should be the selected item — so you should just bind to scheduleCollection:

<DataGrid IsReadOnly="true" ItemsSource="{Binding scheduleCollection}">

(… and either use AutoGenerateColumns="true", or add the DataGridColumns manually)
