    <p>I have a 2-dimensional array of objects and I basically want to databind each one to a cell in a WPF grid. Currently I have this working but I am doing most of it procedurally. I create the correct number of row and column definitions, then I loop through the cells and create the controls and set up the correct bindings for each one. </p> <p>At a minimum I would like to be able to use a template to specify the controls and bindings in xaml. Ideally I would like to get rid of the procedural code and just do it all with databinding, but I'm not sure that's possible.</p> <p>Here is the code I am currently using:</p> <pre><code>public void BindGrid() { m_Grid.Children.Clear(); m_Grid.ColumnDefinitions.Clear(); m_Grid.RowDefinitions.Clear(); for (int x = 0; x &lt; MefGrid.Width; x++) { m_Grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star), }); } for (int y = 0; y &lt; MefGrid.Height; y++) { m_Grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star), }); } for (int x = 0; x &lt; MefGrid.Width; x++) { for (int y = 0; y &lt; MefGrid.Height; y++) { Cell cell = (Cell)MefGrid[x, y]; SolidColorBrush brush = new SolidColorBrush(); var binding = new Binding("On"); binding.Converter = new BoolColorConverter(); binding.Mode = BindingMode.OneWay; BindingOperations.SetBinding(brush, SolidColorBrush.ColorProperty, binding); var rect = new Rectangle(); rect.DataContext = cell; rect.Fill = brush; rect.SetValue(Grid.RowProperty, y); rect.SetValue(Grid.ColumnProperty, x); m_Grid.Children.Add(rect); } } } </code></pre>

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.
