    <p>I'm trying to replace the content of a WPF grid control by another WPF grid defined in a second XAML file in code (c#).</p> <p>(simplified example) Window1.xaml: </p> <pre><code>&lt;Window x:Class="Demo1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"&gt; &lt;DockPanel&gt; &lt;Menu DockPanel.Dock="Top"&gt; &lt;MenuItem Header="_Set Grid" Click="MenuItem_Click" /&gt; &lt;/Menu&gt; &lt;StatusBar DockPanel.Dock="Bottom"&gt; &lt;StatusBarItem Name="statusItem"&gt;Status&lt;/StatusBarItem&gt; &lt;/StatusBar&gt; &lt;Grid Name="header" DockPanel.Dock="Top"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition /&gt; &lt;ColumnDefinition /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;TextBlock Name="txtHi" Grid.Row="0" Grid.Column="0"&gt;Hi&lt;/TextBlock&gt; &lt;TextBlock Name="txtName" Grid.Row="0" Grid.Column="1"&gt;X&lt;/TextBlock&gt; &lt;/Grid&gt; &lt;Grid Name="gridContent"&gt; &lt;/Grid&gt; &lt;/DockPanel&gt; </code></pre> <p></p> <p>Windows2.xaml contains the grid that replaces gridContent</p> <pre><code>&lt;Window x:Class="Demo1.Window2" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window2" Height="300" Width="300"&gt; &lt;Grid Name="grid2"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition /&gt; &lt;RowDefinition /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition /&gt; &lt;ColumnDefinition /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Label Grid.Column="1" Grid.Row="1"&gt;Hello !!!&lt;/Label&gt; &lt;/Grid&gt; </code></pre> <p></p> <p>The MenuItem_Click event in the code behind Windows1.xaml.cs contains:</p> <pre><code>private void MenuItem_Click(object sender, RoutedEventArgs e) { Window2 win2 = new Window2(); gridContent = win2.grid2; setStatus(); } private void setStatus() { statusItem.Content = "gridContent has " + gridContent.RowDefinitions.Count + " rows and " + gridContent.ColumnDefinitions.Count + " columns."; } </code></pre> <p>Although the statusItem say the gridContent contains 2 rows and 2 columns after a click on the menu, the window is not changed and does not contain the text Hello!!!</p> <p>Any ideas what I'm doing wrong? If there are better solutions to "embed" a grid from a second xaml file, please let me know.</p> <p>Thanks, Robbie</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.
