    <p>Here is the generic soution for arbitrary amount of TextBox'es.</p> <p>The initialization of the TextBox'es list:</p> <pre><code>private readonly List&lt;TextBox&gt; _textBoxes; public MainWindow() { InitializeComponent(); _textBoxes = new List&lt;TextBox&gt; { _textBox1, _textBox2, _textBox3 }; } </code></pre> <p>The version with KeyUp event:</p> <pre><code>private void TextBox_KeyUp(object sender, KeyEventArgs e) { if (e.Key == Key.Tab) return; var current = (TextBox)sender; if (current.Text.Any()) return; var index = _textBoxes.IndexOf(current); if (index == 0) return; var previous = _textBoxes[index - 1]; previous.Focus(); previous.CaretIndex = previous.Text.Length; } </code></pre> <p>The above version dissalows to jump through TextBox'es in press and hold scenario. To get around this, use TextChanged event:</p> <pre><code>private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { var current = (TextBox)sender; if (current.Text.Any()) return; var index = _textBoxes.IndexOf(current); if (index == 0) return; var previous = _textBoxes[index - 1]; previous.Focus(); previous.CaretIndex = previous.Text.Length; } </code></pre> <p>Third solution with PreviewKeyDown that supports only Key.Delete:</p> <pre><code>private void TextBox_PreviewKeyDown(object sender, KeyEventArgs e) { if (e.Key != Key.Delete) return; var current = (TextBox)sender; if (current.Text.Length != 0) return; var index = _textBoxes.IndexOf(current); if (index == 0) return; var previous = _textBoxes[index - 1]; previous.Focus(); previous.CaretIndex = 0; } </code></pre> <p>Fourth solution also with PreviewKeyDown that supports both Key.Delete and Key.Back:</p> <pre><code>private void TextBox_PreviewKeyDown(object sender, KeyEventArgs e) { if (e.Key != Key.Delete &amp;&amp; e.Key != Key.Back) return; var current = (TextBox)sender; if (current.Text.Length != 0) return; var index = _textBoxes.IndexOf(current); if (index == 0) return; var previous = _textBoxes[index - 1]; previous.Focus(); if (e.Key == Key.Delete) previous.CaretIndex = 0; } </code></pre>

    1. COnew List<TextBox>(new[] { _textBox1, _textBox2, _textBox3 }); I'm not sure we need underscropes here. Generally your solution works, but I'm not clear about the second part. And why can't if be done via KeyDown event? So we won't need any TextChanged fixes at all. Do you have any ideas how to make code provided in my answer work with KeyDown? Let me know please.

    2. CO@Mike Key.Delete and Key.Back are not sent to KeyDown event handler but you can use PreviewKeyDown.

    3. CO@Mike I believe that maintaining a list of text boxes is more extensible, flexible, maintanable and have less logic repetitions than making a handler for each text box.

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.
