Body
my question is relatively easy, I guess. I have a page to display my data. On a click on a button I want to open a new page with the datacontext of an element 2 layers above the datacontext of the current element. Explanation: My ViewModel is a class (ViewModelContainer) that contains more ViewModels. One is a summary of values and one is the detailed view of that. <pre><code>public class SummaryViewModel { public int somevalue; // is a property public ObservableCollection<SummarizedItems> items; // is a property } public class DetailsViewModel { public int someOthervalue; // is a property public int stuffA; // is a property public int stuffB; // is a property } public class ViewModelContainer : ViewModelBase { private SummaryViewModel _sum; public SummaryViewModel sum { } // is a property private DetailsViewModel _det; public DetailsViewModel det { } // is a property } </code></pre> The View where I can press a button is bound to the value of the ObservableCollection of SummaryViewModel. Everything is fine till now. When I press the button, a new page, showing the details should be opened. I use an ICommand to handle the click, and pass it the details view as a CommandParameter. <pre><code><Button Name="OpenDetailsButton" Command="{Binding Path=ACommand}" CommandParameter="{DynamicResource Details}" </code></pre> I define a page as a resource in the same file, where the datacontext is still ViewModelContainer. <pre><code><pages:DetailsViewPage DataContext="{Binding Path=det }" x:Key="Details"/> </code></pre> The page opens, but the datacontext is not available. I get the following error: <pre><code> System.Windows.Data Error: 3 : Cannot find element that provides DataContext. </code></pre> Has anyone an idea how I could open the details view and providing the datacontext? I cannot move the DetailsViewModel to another class, because it is only possible to update it there. Thanks

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.
