    <p>I have a dependency property <strong>double Text</strong>, and what I want to accomplish is to rotate (with animation) a line by <strong>Text</strong> degrees whenever I change the value of <strong>Text</strong> property.</p> <p>Is there a better way than to implement OnTextPropertyChanged and there process the animation? Or could that be done rather in XAML?</p> <p>Here is a demonstrating code:</p> <p>MainWindow.xaml</p> <pre><code>&lt;Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:l="clr-namespace:WpfApplication1" x:Class="WpfApplication1.MainWindow" Title="MainWindow" Height="200" Width="200" x:Name="Root"&gt; &lt;Grid&gt; &lt;TextBox Width="50" Height="20" VerticalAlignment="Top" Text="{Binding Text, ElementName=Root, Mode=TwoWay}"/&gt; &lt;Grid Width="100" Height="100" Background="Gray" x:Name="Grid"&gt; &lt;Line Grid.Row="1" X2="100" Y2="100" Stroke="Red"/&gt; &lt;/Grid&gt; &lt;/Grid&gt; &lt;/Window&gt; </code></pre> <p>and MainWindow.xaml.cs (without usings):</p> <pre><code>namespace WpfApplication1 { public partial class MainWindow : Window { public static readonly DependencyProperty TextProperty = DependencyProperty.Register( "Text", typeof(double), typeof(MainWindow), new FrameworkPropertyMetadata(0.0)); public double Text { get { return (double)GetValue(TextProperty); } set { SetValue(TextProperty, value); } } public MainWindow() { InitializeComponent(); } } } </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.
