    Example
    All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.
    The following example demonstrates how to recreate the default card-view header, which contains a ColumnManagerRow to the right of a GroupByControl.
    <Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">
  <Grid.Resources>
    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"
                                       Source="{Binding Source={x:Static Application.Current},
                                                        Path=Orders}"/>
  </Grid.Resources>
  <xcdg:DataGridControl x:Name="OrdersGrid"
                        ItemsSource="{Binding Source={StaticResource cvs_orders}}">
    <xcdg:DataGridControl.View>
      <xcdg:CardView UseDefaultHeadersFooters="False">
        <xcdg:CardView.FixedHeaders>

         <DataTemplate>
           <DockPanel>
             <!-- OneWay binding is used because we want the ColumnManagerRow's height to
                  follow what is defined by the GroupByControl. A FallbackValue
                  is specified so the initial measure pass has an acceptable minimal
                  value.-->
             <xcdg:ColumnManagerRow DockPanel.Dock="Right"
                                    Height="{Binding ElementName=groupByControl,
                                                     Path=ActualHeight,
                                                     Mode=OneWay,
                                                     FallbackValue=60}"/>
             <xcdg:GroupByControl x:Name="groupByControl"/>
