    <p>I have a problem with a TextBox in an application...</p> <p>A window has a Grid with two columns. The left column contains a control with a constant width but with a height that adapts. The right column contains a TextBox that takes up all remaining space in the Grid (and thereby in the Window). </p> <p>The Grid is given a minimal width and height and is wrapped within a ScrollViewer. If the user resizes the window to be smaller than the minimal widht/height of the Grid, scrollbars are displayed.</p> <p>This is exactly how I want it to be. However, a problem occurs when the user starts typing text. If the text is to long to fit in one line in the TextBox, I want the text to wrap. Therefore I set TextWrapping="Wrap" on the TextBox. But since the TextBox has an automatic width and is wrapped in a ScrollViewer (its actually the whole Grid that is wrapped), the TextBox just keeps expanding to the right.</p> <p>I do want the TextBox to expand if the window is expanded, but I don't want the TextBox to expand by the text. Rather the text should wrap inside the available TextBox. If the text don't fit within the TextBox height, a scrollbar should be displayed within the TextBox.</p> <p>Is there a way to accomplish this?</p> <p>Below is some code that shows my problem.</p> <pre><code>&lt;Window x:Class="AdaptingTextBoxes.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="400" Background="DarkCyan"&gt; &lt;Grid Margin="10" Name="LayoutRoot"&gt; &lt;ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"&gt; &lt;Grid MinWidth="300" MinHeight="200"&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="auto" /&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Button Grid.Column="0" Margin="0,0,10,0" Content="Button" Width="100" /&gt; &lt;TextBox Grid.Column="1" AcceptsReturn="True" TextWrapping="Wrap" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Auto" /&gt; &lt;/Grid&gt; &lt;/ScrollViewer&gt; &lt;/Grid&gt; &lt;/Window&gt; </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
