    <p>I have a question of how I can use the visual tree helper to get an object that I need. I have a user controll called DialogItemControll that I call from my main page like this: </p> <pre><code>DialogItemControll ivDialogWindow = new DialogItemControll() ivDialogWindow.ivSave.Click += new RoutedEventHandler(ivSave_Click); ivDialogWindow.Show(); </code></pre> <p>And then I have the method ivSave_Click that gets called when I click the save button on my user controll. That method looks like:</p> <pre><code> void ivSave_Click(object sender, RoutedEventArgs e) { var button = sender as Button; var firstStack = button.Parent as StackPanel; var secondStack = firstStack.Parent as StackPanel; TextBox te = secondStack.FindName("ivUserComment") as TextBox;} </code></pre> <p>This is where you can see my attempts to use the get parent and so on. Not so nicely done. So what I want is to get the whole object like:</p> <pre><code>var controll = ?? as DialogItemControll </code></pre> <p>My DialogItemControll looks like this :</p> <pre><code> &lt;C1:C1Window x:Class="DialogItemControll" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:C1="clr-namespace:C1.Silverlight;assembly=C1.Silverlight" mc:Ignorable="d" d:DesignHeight="418" d:DesignWidth="401"&gt; &lt;Grid x:Name="LayoutRoot" Background="White"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="*" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;StackPanel Grid.Row="0" Margin="5,5,5,5"&gt; &lt;TextBlock Name="ivHelpComment" FontSize="18"&gt;test&lt;/TextBlock&gt; &lt;TextBox Name="ivUserComment" BorderThickness="2,2,2,2" Height="170"&gt;&lt;/TextBox&gt; &lt;StackPanel Orientation="Horizontal" HorizontalAlignment="Right" &gt; &lt;Button Name="ivSave" HorizontalAlignment="Right" Height="22" Width="70" Margin="0,10,20,0" Click="ivSave_Click"&gt;Spara&lt;/Button&gt; &lt;Button Name="ivCancel" HorizontalAlignment="Right" Height="22" Width="70" Margin="0,10,20,0" Click="ivCancel_Click"&gt;Avbryt&lt;/Button&gt; &lt;/StackPanel&gt; &lt;/StackPanel&gt; &lt;/Grid&gt; </code></pre> <p></p> <p>C1 window is the same as user control, its just a third party control. Please help me with how I should use the tree helper in a good way to get the whole object.</p> <p>Thanks</p>

    1. COI'm able to get it by writing: var button = sender as Button; var firstStack = button.Parent as StackPanel; var secondStack = firstStack.Parent as StackPanel; var thirdStack = secondStack.Parent as Grid; var lastItem = thirdStack.Parent as DialogItemControll; But I'm looking for some better way of doing this.

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.
