    <p>The ideal way to do this would be to create a <code>ClickEditableTextBlock</code> control, which by default renders as a TextBlock but shows a TextBox when the user clicks it. Because any given ClickEditableTextBlock has only one TextBlock and one TextBox, you don't have the matching issue. Then you use a ClickEditableTextBlock instead of separate TextBlocks and TextBoxes in your DataTemplate.</p> <p>This has the side benefit of encapsulating the functionality in a control so you don't pollute your main window code-behind with the edit behaviour, plus you can easily reuse it in other templates.</p> <hr> <p>If this sounds like too much effort, you can use Tag or an attached property to associate each TextBlock with a TextBox:</p> <pre><code>&lt;DataTemplate&gt; &lt;StackPanel&gt; &lt;TextBlock Text="whatever" MouseDown="TextBlock_MouseDown" Tag="{Binding ElementName=tb}" /&gt; &lt;TextBox Name="tb" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; </code></pre> <p>Note the use of <code>{Binding ElementName=tb}</code> on the Tag to refer to the TextBox named <code>tb</code>.</p> <p>And in your code-behind:</p> <pre><code>private void TextBlock_MouseDown(object sender, MouseButtonEventArgs e) { FrameworkElement textBlock = (FrameworkElement)sender; TextBox editBox = (TextBox)(textBlock.Tag); editBox.Text = "Wow!"; // or set visible or whatever } </code></pre> <p>(To avoid the use of the nasty Tag property, you could define a custom attached property to carry the TextBox binding, but for brevity I'm not showing that.)</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.
