RE: DataGrid.RowDetailsTemplate

Hi

Define a MaxHeight property for the second datagrid

...

           <DataGrid.RowDetailsTemplate>

               <DataTemplate>

                 <DataGrid

                    x:Name="ordGrid"

                    MaxHeight="200"

                    ItemsSource = "{Binding Path = custOrders}"

...

So if necessary a separate scrollbar will be created for the second datagrid

Regards
