    <p>In my presentation layer (PrintViewModel.cs) I have the following code where I expose my dataset that will be used to populate a datagrid.</p> <pre><code> public const string ViewFullRecipeGroupingPropertyName = "ViewFullRecipeGrouping"; public List&lt;ViewFullRecipe&gt; _viewFullRecipeGrouping = new List&lt;ViewFullRecipe&gt;(); public List&lt;ViewFullRecipe&gt; ViewFullRecipeGrouping { get { return _viewFullRecipeGrouping; } set { Set(ViewFullRecipeGroupingPropertyName, ref _viewFullRecipeGrouping, value, true); } } </code></pre> <p>Now in my view layer (PrintPage.xaml.cs) I am creating a datagrid programatically and when done I need to set the itemsource, something like this:</p> <pre><code> private void Window_Loaded(object sender, RoutedEventArgs e) { var datagrid = new DataGrid(); datagrid.ItemsSource = PrintViewModel.ViewFullRecipeGrouping; } </code></pre> <p>However this is generating the following error:<br> An object reference is required for the non-static field, method, or property 'Presentation.Print.PrintViewModel.ViewFullRecipeGrouping.get'</p> <p>I know my dataset is ok because if I set it directly in the XAML it works perfectly fine (for my test datagrid created in the XAML itself).</p> <p>So, I guess the issue is on HOW I am accessing ViewFullRecipeGrouping from the PRESENTATION layer (in my VIEW layer).</p> <p>This is how the PrintViewModel is instantiated:</p> <pre><code>public class ViewModelLocator { static ViewModelLocator() { SimpleIoc.Default.Register&lt;PrintViewModel&gt;(true); } public PrintViewModel Print { get { return ServiceLocator.Current.GetInstance&lt;PrintViewModel&gt;(); } } </code></pre> <p>Any ideas or suggestions on either how to get this work or a better way (am I violating MVVM here?) Thanks,</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
