    <p>Although the DataGrid does not expose a Header Background property, it does have a property for the ColumnHeaderStyle. Using the technique that DaniCE has previously suggested for a single column we can replace the header template for all header columns including the empty space on the right hand side. The down side with replacing the entire template for a header is that we lose the sorting arrows and separators which are present in the default header template. Fortunately we can use a <a href="http://jesseliberty.com/2008/10/03/template-browser-%E2%80%93-an-indispensible-tool/" rel="nofollow noreferrer">template browser</a> to extract the default template being used and then modify a copy of it.</p> <p>Here I've thrown together a quick example that will change the background of the column headers to LightBlue while keeping the separators and sorting. Take a look at the default DataGridColumnHeader template in a <a href="http://jesseliberty.com/2008/10/03/template-browser-%E2%80%93-an-indispensible-tool/" rel="nofollow noreferrer">template browser</a> to see how to deal with modifying the Background when the mouse hovers over the ColumnHeader.</p> <p><a href="http://i34.tinypic.com/2q2ixch.jpg" rel="nofollow noreferrer">DataGrid Header Background http://i34.tinypic.com/2q2ixch.jpg</a></p> <pre><code>&lt;data:DataGrid x:Name="grid"&gt; &lt;data:DataGrid.ColumnHeaderStyle&gt; &lt;Style xmlns:primitives="clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls.Data" xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows" TargetType="primitives:DataGridColumnHeader" &gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate TargetType="primitives:DataGridColumnHeader"&gt; &lt;Grid Name="Root"&gt; &lt;vsm:VisualStateManager.VisualStateGroups&gt; &lt;vsm:VisualStateGroup x:Name="SortStates" &gt; &lt;vsm:VisualStateGroup.Transitions&gt; &lt;vsm:VisualTransition GeneratedDuration="00:00:0.1" /&gt; &lt;/vsm:VisualStateGroup.Transitions&gt; &lt;vsm:VisualState x:Name="Unsorted" /&gt; &lt;vsm:VisualState x:Name="SortAscending"&gt; &lt;Storyboard&gt; &lt;DoubleAnimation Storyboard.TargetName="SortIcon" Storyboard.TargetProperty="Opacity" Duration="0" To="1.0" /&gt; &lt;/Storyboard&gt; &lt;/vsm:VisualState&gt; &lt;vsm:VisualState x:Name="SortDescending"&gt; &lt;Storyboard&gt; &lt;DoubleAnimation Storyboard.TargetName="SortIcon" Storyboard.TargetProperty="Opacity" Duration="0" To="1.0" /&gt; &lt;DoubleAnimation Storyboard.TargetName="SortIconTransform" Storyboard.TargetProperty="ScaleY" Duration="0" To="-.9" /&gt; &lt;/Storyboard&gt; &lt;/vsm:VisualState&gt; &lt;/vsm:VisualStateGroup&gt; &lt;/vsm:VisualStateManager.VisualStateGroups&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="*" /&gt; &lt;RowDefinition Height="*" /&gt; &lt;RowDefinition Height="Auto" /&gt; &lt;/Grid.RowDefinitions&gt; &lt;Grid.ColumnDefinitions&gt; &lt;ColumnDefinition Width="Auto" /&gt; &lt;ColumnDefinition Width="*" /&gt; &lt;ColumnDefinition Width="Auto" /&gt; &lt;/Grid.ColumnDefinitions&gt; &lt;Rectangle x:Name="BackgroundRectangle" Stretch="Fill" Fill="LightBlue" Grid.ColumnSpan="2" Grid.RowSpan="2" /&gt; &lt;ContentPresenter Grid.RowSpan="2" Content="{TemplateBinding Content}" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Margin="{TemplateBinding Padding}" /&gt; &lt;Rectangle Name="VerticalSeparator" Grid.RowSpan="2" Grid.Column="2" Width="1" VerticalAlignment="Stretch" Fill="{TemplateBinding SeparatorBrush}" Visibility="{TemplateBinding SeparatorVisibility}" /&gt; &lt;Path Grid.RowSpan="2" Name="SortIcon" RenderTransformOrigin=".5,.5" HorizontalAlignment="Left" VerticalAlignment="Center" Opacity="0" Grid.Column="1" Stretch="Uniform" Width="8" Data="F1 M -5.215,6.099L 5.215,6.099L 0,0L -5.215,6.099 Z "&gt; &lt;Path.Fill&gt; &lt;SolidColorBrush Color="#FF444444" /&gt; &lt;/Path.Fill&gt; &lt;Path.RenderTransform&gt; &lt;TransformGroup&gt; &lt;ScaleTransform x:Name="SortIconTransform" ScaleX=".9" ScaleY=".9" /&gt; &lt;/TransformGroup&gt; &lt;/Path.RenderTransform&gt; &lt;/Path&gt; &lt;/Grid&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; &lt;/data:DataGrid.ColumnHeaderStyle&gt; &lt;/data:DataGrid&gt; </code></pre> <p>Hope this helps!</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.

SQuiL has stopped working due to an internal error.

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