    <p>I have a DataGrid (WPF 4) like this:</p> <pre><code>&lt;DataGrid Margin="0,0,0,5" VerticalAlignment="Top" Height="192" BorderBrush="#aaa" Background="White" HorizontalAlignment="Left" ItemsSource="{Binding Namen, Mode=OneWay}" ScrollViewer.VerticalScrollBarVisibility="Visible" AutoGenerateColumns="False" ColumnHeaderHeight="24" SelectionChanged="DataGridAuslaendischeAlteNamen_SelectionChanged"&gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Width="*" Header="Namenseintrag" Binding="{Binding DisplayName, Mode=OneWay}" /&gt; &lt;DataGridTextColumn Width="75" Header="gültig von" Binding="{Binding GueltigAb, StringFormat=d, Mode=OneWay}" /&gt; &lt;DataGridTextColumn Width="75" Header="gültig bis" Binding="{Binding GueltigBis, StringFormat=d., Mode=OneWay}" /&gt; &lt;DataGridTemplateColumn Width="20" IsReadOnly="True"&gt; &lt;DataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;Button Style="{DynamicResource CaratRemoveButton}" Click="Button_Click" CommandParameter="{Binding}" PreviewMouseDown="Button_PreviewMouseDown" /&gt; &lt;/DataTemplate&gt; &lt;/DataGridTemplateColumn.CellTemplate&gt; &lt;/DataGridTemplateColumn&gt; &lt;/DataGrid.Columns&gt; &lt;/DataGrid&gt; </code></pre> <p>The issue I experience is, that a button of the <code>DataGridTemplateColumn</code> does not fire the click-event, if its row is not selected. So I have to click a button twice, one time to select its row and then to raise the click event. I read about similiar problems with checkbox-columns, but there the suggestion was obviously to use a template column. I tested to use the PreviewMouseDown-Event of the button, which works, but is not what I want, since then the button does not follow its usual grpahical click behaviour.</p> <p>What am I missing here? How can I get that click event by just clicking once, regardless of whether the row was selected or not?</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.
