    <p>You can use a <code>MultiBinding</code>, with a first binding taking the actual data context from the cell (that would be the row), and the second one taking the column. From there, you can retrieve the cell value.</p> <p>Converter code:</p> <pre><code>public class RowColumnToCellConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture) { DataRowView row = values[0] as DataRowView; DataGridColumn column = values[1] as DataGridColumn; return row != null &amp;&amp; column != null ? row[column.SortMemberPath] : DependencyProperty.UnsetValue; } public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture) { throw new NotSupportedException(); } } </code></pre> <p>XAML:</p> <pre><code> &lt;Style x:Key="{x:Type DataGridCell}" TargetType="{x:Type DataGridCell}"&gt; &lt;Setter Property="Template"&gt; &lt;Setter.Value&gt; &lt;ControlTemplate&gt; &lt;StackPanel&gt; &lt;TextBlock x:Name="TextOK" Text="OK" Visibility="Collapsed" /&gt; &lt;/StackPanel&gt; &lt;ControlTemplate.Triggers&gt; &lt;DataTrigger Value="True"&gt; &lt;DataTrigger.Binding&gt; &lt;MultiBinding Converter="{StaticResource RowColumnToCellConverter}"&gt; &lt;Binding /&gt; &lt;Binding RelativeSource="{x:Static RelativeSource.Self}" Path="Column" /&gt; &lt;/MultiBinding&gt; &lt;/DataTrigger.Binding&gt; &lt;Setter TargetName="TextOK" Property="Visibility" Value="Visible" /&gt; &lt;/DataTrigger&gt; &lt;/ControlTemplate.Triggers&gt; &lt;/ControlTemplate&gt; &lt;/Setter.Value&gt; &lt;/Setter&gt; &lt;/Style&gt; </code></pre> <p>I used a <code>TextBlock</code> instead an image for testing, but the code will be the same. Just avoid defining a style for the image if that can be done directly in the <code>DataGridCell</code>'s style.</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).
