    <p>I'm trying to display a "No record found" Message in my WPF Datagrid</p> <p>I tried the solution from the same question here: <a href="https://stackoverflow.com/questions/4687414/show-no-record-found-message-on-a-wpf-datagrid-when-its-empty">Show &quot;No record found&quot; message on a WPF DataGrid when it&#39;s empty</a></p> <p>But so far I didn't find a way to add a empty line only when my ObservableCollection is empty. This is the code for my datagrid:</p> <pre><code> &lt;DataGrid DataContext="{Binding RelativeSource={RelativeSource AncestorType=Window}}" ItemsSource="{Binding CameraListObjCode}" AutoGenerateColumns="False" Height="145" HorizontalAlignment="Left" Margin="62,105,0,0" Name="dataGrid1" VerticalAlignment="Top" Width="361" IsReadOnly="True"&gt; &lt;DataGrid.Resources&gt; &lt;conv:IntIsEqualOrGreaterThan x:Key="intIsEqualOrGreaterThan"/&gt; &lt;conv:IntIsLessThan x:Key="intIsLessThan"/&gt; &lt;Style TargetType="DataGrid"&gt; &lt;Setter Property="RowDetailsVisibilityMode" Value="Collapsed"&gt;&lt;/Setter&gt; &lt;Style.Triggers&gt; &lt;!--&lt;DataTrigger Binding="{Binding Path=CameraListObjCode.Count, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}, Converter={StaticResource intIsEqualOrGreaterThan}, ConverterParameter=1}" Value="True"&gt;--&gt; &lt;DataTrigger Binding="{Binding Path=CameraListObjCode.Count, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}, Converter={StaticResource intIsLessThan}, ConverterParameter=1}" Value="True"&gt; &lt;Setter Property="RowHeight" Value="0"&gt;&lt;/Setter&gt; &lt;Setter Property="RowDetailsVisibilityMode" Value="Visible"&gt;&lt;/Setter&gt; &lt;/DataTrigger&gt; &lt;/Style.Triggers&gt; &lt;/Style&gt; &lt;/DataGrid.Resources&gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="Camera Model:" Binding="{Binding CameraModel}" /&gt; &lt;DataGridTextColumn Header="Serial Nr:" Binding="{Binding SerialNr}" /&gt; &lt;DataGridTextColumn Header="IP Address:" Binding="{Binding IPAddress}" /&gt; &lt;/DataGrid.Columns&gt; &lt;DataGrid.RowDetailsTemplate&gt; &lt;DataTemplate&gt; &lt;StackPanel&gt; &lt;TextBlock Text="No Record Found" Visibility="Visible" /&gt; &lt;/StackPanel&gt; &lt;/DataTemplate&gt; &lt;/DataGrid.RowDetailsTemplate&gt; &lt;/DataGrid&gt; </code></pre> <p>The Triggers all work as as expected. But the message is not displayed. When I change the Trigger Converter from "intIsLessThan" to "intIsEqualOrGreaterThan" the Message is shown instead of the actual datagrid entry.</p> <p>So I guess just the empty default row is missing. But how can I add an empty default row?</p> <p>I hope anyone can help me with this problem. I'm already searching for two days now to find a solution...</p>

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.
