    <p>I have a DataGrid and in that DataGrid's DataGrid.RowDetailsTemplate I have put another DataGrid.Now my first Datagrid is having ItemsSource="{Binding MatchObsCollection}" and My inner Datagrid which is in my DataGrid.RowDetailsTemplate has separate ItemSource. But inner Datagrid is notpopulating. I am using MVVM and I am binding both the Datagrid s by ObservableCollections on Viewmodel. Can anyone help me please(My question is almost same as <a href="https://stackoverflow.com/questions/9773162/displaying-hierarchal-parent-child-data-in-wpf-datagrid">Displaying hierarchal parent child data in WPF DataGrid</a> but I have not found any good answer in that post also) .My xaml code is attached below.Thanking you, </p> <pre><code>&lt;DataGrid HorizontalAlignment="Stretch" Margin="0" x:Name="dataGridParent" ItemsSource="{Binding MatchObsCollection}" Style="{StaticResource EfesDataGridStyle}" FrozenColumnCount="14" GridLinesVisibility="All" HorizontalGridLinesBrush="#DADADA" VerticalGridLinesBrush="#DADADA" Cursor="Hand" AutoGenerateColumns="False" RowDetailsVisibilityMode="Visible" util:ParentMatchDataGridRowClickHandler.MethodName="ParentMatchDatagrdRowClick" SelectedItem="{Binding SelectedMatch}" &gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="Kod" Binding="{Binding MatchNo}" Width="50*" /&gt; &lt;DataGridTextColumn Header="Tarih" Binding="{Binding MatchDate}" Width="70*"/&gt; &lt;DataGridTextColumn Header="Ev Sahibi" Binding="{Binding MatchHome}" Width="100*"/&gt; &lt;DataGridTextColumn Header="Konuk" Binding="{Binding MatchVisitor}" Width="50*"/&gt; &lt;DataGridTextColumn Header="1" Binding="{Binding MatchResultHomeOdds}" Width="30*" &gt;&lt;/DataGridTextColumn&gt; &lt;DataGridTextColumn Header="X" Binding="{Binding MatchResultDrawOdds}" Width="30*" /&gt; &lt;DataGridTextColumn Header="2" Binding="{Binding MatchResultVisitorOdds}" Width="30*"/&gt; &lt;DataGridTextColumn Header="T1" Binding="{Binding MatchresultSingleHomeOdds}" Width="30*" /&gt; &lt;DataGridTextColumn Header="TX" Binding="{Binding MatchresultSingleDrawOdds}" Width="30*" /&gt; &lt;DataGridTextColumn Header="T2" Binding="{Binding MatchresultSingleVisitorOdds}" Width="30*" /&gt; &lt;DataGridTextColumn Header="+" CellStyle ="{StaticResource DataGridCellStyle}" Binding="{Binding TotalBets}" Width="30*"/&gt; &lt;DataGridTextColumn Header="Min" Binding="{Binding MatchMin}" Width="30*" /&gt; &lt;DataGridTextColumn Header="Lig" Binding="{Binding TeamName}" Width="70*" /&gt; &lt;DataGridTemplateColumn Header="Durum" Width="Auto" &gt; &lt;DataGridTemplateColumn.CellTemplate&gt; &lt;DataTemplate&gt; &lt;ToggleButton x:Name="toggleBtn" VerticalAlignment="Center" Margin="0" Style="{StaticResource SlidingToggleButton}" BorderBrush="{x:Null}" IsChecked="{Binding ToggleBtn}" Background="#FF2F63FF" /&gt; &lt;/DataTemplate&gt; &lt;/DataGridTemplateColumn.CellTemplate&gt; &lt;/DataGridTemplateColumn&gt; &lt;/DataGrid.Columns&gt; &lt;DataGrid.RowDetailsTemplate x:Uid="test123"&gt; &lt;DataTemplate x:Name="testTemplete"&gt; &lt;DataGrid x:Name="innerGrid" ItemsSource="{Binding SubBetMatchDataListforChildGrid}" Style="{StaticResource EfesDataGridStyle}" Margin="50,2,2,2" MinHeight="40" GridLinesVisibility="All" HorizontalGridLinesBrush="#DADADA" VerticalGridLinesBrush="#DADADA" Visibility="Collapsed" &gt; &lt;DataGrid.Columns&gt; &lt;DataGridTextColumn Header="Kod" Binding="{Binding Code}" Width="3*" /&gt; &lt;DataGridTextColumn Header="Alt Secenakler" Binding="{Binding SubOptions}" Width="7*" /&gt; &lt;/DataGrid.Columns&gt; &lt;/DataGrid&gt; &lt;/DataTemplate&gt; &lt;/DataGrid.RowDetailsTemplate&gt; &lt;/DataGrid&gt; </code></pre>

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.

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