Body
<p>I was asked to create custom TreeView based on basic TreeView from SDK. It all works, problem is: nodes/leaves do not stretch to their content, their width is always the same. Here's xaml markup:</p> <pre><code><Grid xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' xmlns:sdk='http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk'> <Grid.Resources> <Style x:Key='TreeViewChildStyle' TargetType='sdk:TreeViewItem'> <Setter Property='HorizontalContentAlignment' Value='Stretch'/> <Setter Property='Background' Value='Blue'/> </Style> <sdk:HierarchicalDataTemplate x:Key='ChildTemplate' x:Name='ChildTemplate'> <TextBlock HorizontalAlignment='Stretch' Text='{Binding Path=ChildPath}'/> </sdk:HierarchicalDataTemplate> <sdk:HierarchicalDataTemplate x:Key='NameTemplate' ItemsSource='{Binding Path= ChildrenCollectionPath}' x:Name='NameTemplate' ItemTemplate='{StaticResource ChildTemplate}'> <TextBlock HorizontalAlignment='Stretch' Text='{Binding Path=ParentPath}' Width='1000'/> </sdk:HierarchicalDataTemplate> </Grid.Resources> <sdk:TreeView Height='Auto' Background='Red' ItemContainerStyle='{StaticResource TreeViewChildStyle}' Name='treeView1' ItemTemplate='{StaticResource NameTemplate} VerticalAlignment='Stretch' HorizontalAlignment='Stretch' BorderThickness='0'/> </Grid> </code></pre> <p>I've already tried setting ItemContainer width in code behind, setting TextBlocks' width to 'Auto', setting ItemContainer width in style markup. Nothing works, TreeViewItems are always same width and it's way too narrow.</p> <p>Edit: Yes, there is SDK namespace added to grid, something just happened to editor and it's not shown, can't help it.</p> <p>Edit2: The TreeView actually changes its width to given value, yet, its Items are still not scaling.</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.
