The following example demonstrates how to clear the content of all header and footer sections of a grid using its view's UseDefaultHeadersFooters property.

XAML
Copy Code 
<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:DataGridControl.View>

   </xcdg:DataGridControl>

</Grid>
VB.NET
Copy Code 
Dim view As New CardView()

view.UseDefaultHeadersFooters = False

dataGridControl.View = view
C#
Copy Code 
CardView view = new CardView();

view.UseDefaultHeadersFooters = false;

dataGridControl.View = view;
