    <p>I'm new to WPF, and am having trouble getting the values for properties for a custom user control from the MainWindow XAML file.</p> <p>Here, I want to get the value "8" as the number of rows and columns but in my InitializeGrid() method, the properties are never set. They are always "0". What am I doing wrong?</p> <p>Any references will also be appreciated.</p> <hr> <p>This is my MainWindow.xaml (the relevant portions):</p> <pre><code>&lt;local:BoardView BoardRows="8" BoardColumns="8" /&gt; </code></pre> <p>This is my BoardView.xaml:</p> <pre><code>&lt;UniformGrid Name="uniformGrid" Rows="{Binding BoardRows}" Columns="{Binding BoardColumns}" &gt; &lt;/UniformGrid&gt; &lt;/UserControl&gt; </code></pre> <p>And this is my BoardView.xaml.cs:</p> <pre><code>[Description("The number of rows for the board."), Category("Common Properties")] public int BoardRows { get { return (int)base.GetValue(BoardRowsProperty); } set { base.SetValue(BoardRowsProperty, value); } } public static readonly DependencyProperty BoardRowsProperty = DependencyProperty.Register("BoardRows", typeof(int), typeof(UniformGrid)); [Description("The number of columns for the board."), Category("Common Properties")] public int BoardColumns { get { return (int)base.GetValue(BoardColumnsProperty); } set { base.SetValue(BoardColumnsProperty, value); } } public static readonly DependencyProperty BoardColumnsProperty = DependencyProperty.Register("BoardColumns", typeof(int), typeof(UniformGrid)); public BoardView() { InitializeComponent(); DataContext = this; InitializeGrid(); } private void InitializeGrid() { int rows = BoardRows; int cols = BoardColumns; for (int i = 0; i &lt; rows; i++) { for (int j = 0; j &lt; cols; j++) { uniformGrid.Children.Add( ... ); // ... } } } </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
