Инфраструктура xamDataGrid и связывание с Entity Framework

Question

У меня есть рабочий пример кода, который использует Entity Framework, который связывает таблицы базы данных SQL. Он использует стандарт DataGrid. Я пытаюсь поменять код, чтобы использовать xamDataGrid, но отсутствует RowDetailsVisibilityMode = "VisibleWhenSelected". Я пытаюсь отобразить 2 сетки и мастер и родительский элемент, чтобы при нажатии на строку в мастере отображались подробности. Затем я могу отредактировать сетку на сетке деталей и обновить базу данных.

Это xaml, который работает:

   <DataGrid x:Name="categoriesDataGrid" Grid.Row="0"  AutoGenerateColumns="False" EnableRowVirtualization="True" ItemsSource="{Binding Source={StaticResource categoriesViewSource}}" Margin="0,0,0,0" RowDetailsVisibilityMode="VisibleWhenSelected">
            <DataGrid.Columns>
            <DataGridTextColumn x:Name="categoryIDColumn" Binding="{Binding CategoryID}" Header="Category ID" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="categoryNameColumn" Binding="{Binding CategoryName}" Header="Category Name" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="descriptionColumn" Binding="{Binding Description}" Header="Description" Width="400"/>
        </DataGrid.Columns>
    </DataGrid>
    <DataGrid x:Name="productsDataGrid" Grid.Row="1" AutoGenerateColumns="False" EnableRowVirtualization="True" ItemsSource="{Binding Source={StaticResource categoriesProductsViewSource}}" Margin="18,3,21,7" RowDetailsVisibilityMode="VisibleWhenSelected" >
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="categoryIDColumn1" Binding="{Binding CategoryID}" Header="Category ID" Width="SizeToHeader"/>
            <DataGridCheckBoxColumn x:Name="discontinuedColumn" Binding="{Binding Discontinued}" Header="Discontinued" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="productIDColumn" Binding="{Binding ProductID}" Header="Product ID" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="productNameColumn" Binding="{Binding ProductName}" Header="Product Name" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="quantityPerUnitColumn" Binding="{Binding QuantityPerUnit}" Header="Quantity Per Unit" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="reorderLevelColumn" Binding="{Binding ReorderLevel}" Header="Reorder Level" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="supplierIDColumn" Binding="{Binding SupplierID}" Header="Supplier ID" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="unitPriceColumn" Binding="{Binding UnitPrice}" Header="Unit Price" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="unitsInStockColumn" Binding="{Binding UnitsInStock}" Header="Units In Stock" Width="SizeToHeader"/>
            <DataGridTextColumn x:Name="unitsOnOrderColumn" Binding="{Binding UnitsOnOrder}" Header="Units On Order" Width="SizeToHeader"/>
        </DataGrid.Columns>
    </DataGrid>

Это xamdataGrid, который не работает, когда я нажимаю на главную строку:

   <igDP:XamDataGrid x:Name="categoriesDataGrid" Grid.Row="0" DataSource="{Binding}"  MouseDoubleClick="categoriesDataGrid_MouseDoubleClick">

        <igDP:XamDataGrid.FieldLayoutSettings>
            <igDP:FieldLayoutSettings AutoGenerateFields="False"/>
        </igDP:XamDataGrid.FieldLayoutSettings>

        <igDP:XamDataGrid.FieldLayouts>
            <igDP:FieldLayout>

                <igDP:UnboundField Name="CategoryID" Width="40" Binding="{Binding CategoryID}">
                    <igDP:Field.Settings>
                        <igDP:FieldSettings  />
                    </igDP:Field.Settings>
                </igDP:UnboundField>
                <igDP:Field Name="CategoryID" Width="40" >

                        <igDP:FieldSettings  />
                    </igDP:Field.Settings>
                </igDP:Field>
                <igDP:UnboundField Name="CategoryName" Width="Auto" Binding="{Binding CategoryName}" >

                        <igDP:FieldSettings />
