    <p>I have an ItemsControl control that displays some buttons. When I click on one of the buttons I have to show some details of the selected resource (bound to the button).</p> <p>So when the button is clicked I set a property on the ViewModel called SelectedResource.</p> <p>That's working fine, what I'd like to do is to highlight the button clicked.</p> <p>I have a ControlTemplate for my button as follows:</p> <pre><code>&lt;ControlTemplate x:Key="ResourceButtonTemplate" TargetType="{x:Type ButtonBase}"&gt; &lt;Border Name="SelectedButtonBorder" CornerRadius="3"&gt; &lt;Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3" Background="{TemplateBinding Background}" SnapsToDevicePixels="True"&gt; &lt;StackPanel Orientation="Horizontal" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"&gt; &lt;Image Source="{Binding Type.Value, Converter={converter:ResourceTypeToStringConverter}}"&gt;&lt;/Image&gt; &lt;ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Focusable="False" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/&gt; &lt;/StackPanel&gt; &lt;/Border&gt; &lt;/Border&gt; &lt;ControlTemplate.Triggers&gt; &lt;DataTrigger Binding="{Binding SelectedResource}" Value=""&gt; &lt;Setter TargetName="SelectedButtonBorder" Property="BorderBrush" Value="Red" /&gt; &lt;Setter TargetName="SelectedButtonBorder" Property="BorderThickness" Value="2" /&gt; &lt;/DataTrigger&gt; &lt;/ControlTemplate.Triggers&gt; &lt;/ControlTemplate&gt; </code></pre> <p>I've tried the DataTrigger, but I can't bind the value property of the datatrigger.</p> <p>So, is there a way to do that using only XAML?</p> <p><strong>Edit:</strong></p> <p>I don't want to compare the SelectedResource to an empty string, I actually don't know what to compare to. I tried to compare one of the properties of the SelectedResource object to the text shown on the button.</p>

    3. COSelected is not a string, but it has a string property that I use to show in the content of the button. I tried to compare both but it didn't work

Guidance
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).
