    <p>In MainPage.xaml.cs (Silverlight Application) I can do something like this:</p> <pre><code>StackPanel myStackPanel = new StackPanel(); Button myButton = new Button(); myButton.Content = "Button"; myButton.Width = 200; myButton.Height = 30; Button myButton1 = new Button(); myButton1.Content = "Button 1"; myButton1.Width = 200; myButton1.Height = 30; myStackPanel.Children.Add(myButton); myStackPanel.Children.Add(myButton1); this.LayoutRoot.Children.Add(myStackPanel); </code></pre> <p>What is the equivalent of this code in a custom control when I'm trying to create these controls from the code?</p> <p><strong>Update:</strong></p> <p>My question is probably too confusing. I'l try better formulation. So, I have</p> <p><strong>Generic.xaml</strong></p> <pre><code>&lt;ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:DemoAddControlLib"&gt; &lt;Style TargetType="local:DemoControlShowtime"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="local:DemoControlShowtime"&gt; &lt;Grid x:Name="LayoutRootControl"&gt; &lt;Button x:Name="Button1" Content="Hi" Width="150" Height="30"&gt;&lt;/Button&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; &lt;/ResourceDictionary&gt; </code></pre> <p>And code:</p> <p><strong>DemoControlShowtime.cs</strong></p> <pre><code>[TemplatePart(Name = "Button1", Type=typeof(Button))] public class DemoControlShowtime : Control { public DemoControlShowtime() { this.DefaultStyleKey = typeof(DemoControlShowtime); } // Events public override void OnApplyTemplate() { Button1 = (Button)GetTemplateChild("Button1"); } private Button button1; private Button Button1 { get { return button1; } set { if (button1 != null) { Button1.Click -= new RoutedEventHandler(myButton_Click); } button1 = value; button1.Click += new RoutedEventHandler(myButton_Click); } } void myButton_Click(object sender, RoutedEventArgs e) { Button1.Content = "Hello Button"; } } </code></pre> <p>If I click on Button1 the Content changes from "Hi" to "Hello Button". I want, when Button1 is clicked, to add StackPanel with two buttons as its Children into the Grid LayoutRootControl. I know there is Visibility property and put it into the xaml would be easier but I'm curious how to do it from the code.</p> <p>I hope this is much clearer than the question was before.</p>

    1. COCould you clarify your question? I don't understand exaclty what you're looking for. Are you wondering how to add a CustomControl to your myStackPanel? Or are you wondering how to make myStackPanel be a custom control that you add to the LayoutRoot?

    2. COI'm interested how to add programmatically StackPanel with its Children to my Custom Control (Silverlight Library) - i.e. MyDemoControl.cs (here should be the code with myStackPanel) + Generic.xaml. Maybe I'm accessing the problem in a totally wrong way.

    3. COSo you would like to do something like this: MyDemoControl has a button and a MyCustomControl, where MyCustomControl has something in it (like a StackPanel)?

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.
