    <p>Why is the Canvas covering the other Children of the Dock Panel? I'm setting up a menu bar at the top of the client area and a status bar at the bottom of the client area of the window as per standard convention in xaml as follows:</p> <pre><code>&lt;Window x:Class="RichCoreW.ScenEditWnd" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="ScenEditWnd" Height="490" Width="776" HorizontalAlignment="Right"&gt; &lt;DockPanel Name="mapDockP"&gt; &lt;Menu IsMainMenu="True" DockPanel.Dock="Top"&gt; &lt;MenuItem Header="File"&gt; &lt;MenuItem Header="Save" Name="menuISave" Click="menuISave_Click"/&gt; &lt;MenuItem Header="Make Playable" Click="MakePlayable" /&gt; &lt;/MenuItem&gt; &lt;MenuItem Command="ApplicationCommands.Help" /&gt; &lt;/Menu&gt; &lt;StackPanel DockPanel.Dock="Bottom" Name="stackPanel1" Orientation="Horizontal" background="Yellow"&gt; &lt;Label Content="Playable:" Name="label1" /&gt; &lt;Label Name="labPlayable" /&gt; &lt;/StackPanel&gt; &lt;/DockPanel&gt; &lt;/Window&gt; </code></pre> <p>Then I add a an instance of the MapCanvEdit Class which inherits from Canvas in C# code as follows. As its the last child to be added to the Dockpanel it should take the remaining space in the Dockpanel. But it covers the menu and status bars as well covering the whole of the client area. To be precise it is the children of the Canvas that cover over the other two Stack Panels. Where the Canvas(MapCanvEdit) is empty you can see the Menu and Status bars:</p> <pre><code>public partial class ScenEditWnd : Window { ScenC scenC; MapCanvEdit mapCanvE; public ScenEditWnd(ScenC scenCI) { InitializeComponent(); scenC = scenCI; mapCanvE = new MapCanvEdit(scenC); mapDockP.Children.Add(mapCanvE); MouseWheel += mapCanvE.Zoom; mapCanvE.SizeChanged += delegate { mapCanvE.DrawHexs(); }; ContentRendered += delegate { mapCanvE.DrawHexs(); }; labPlayable.Content = scenC.playable.ToString(); } } </code></pre> <p>I've left out the other methods for simplicity. Any help appreciated!</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.
