DataGrid Fundamentals: Views and Themes Overview

The CardView and CompactCardView classes provide card-view layouts for the data items in a grid. Either layout can be used to display data items as cards; however, the compact card-view layout applies well when a database has many columns but few of the fields contain data. In this case, the fields that do not contain data will not be displayed in the cards, giving them a more compact appearance.  

The terms "card" and "insertion card" respectively refer to the DataRow and InsertionRow objects displayed in a grid's viewport when a grid is in a card-view layout.

By default, the data displayed in a card's title is determined by a grid's main (primary) column. The content of the cell whose field name matches the field name of the main column will be displayed in the corresponding card's title. If left unmodified, the main column will be the first column that is added to a grid's Columns collection; however, the main column can be changed by setting a column's IsMainColumn property to true (see Example 3).

The last column whose IsMainColumn property is set to true will be considered as a grid's main (primary) column.
The background and foreground of the card (including insertion card) titles can be modified through the CardTitleBackground and CardTitleForeground properties. DataTemplates can be provided through the CardTitleTemplate and InsertionCardTitleTemplate properties for complete control over the appearance of the card titles (see Templates).
The width of the cards—more specifically a "column" of cards—can be modified through the CardWidth property. Any insertion cards placed in the header and/or footer sections will acquire the width defined by the CardWidth property; however, insertion cards placed in the fixed header or fixed footer sections will not. Separator lines can also be drawn between card "columns" using the SeparatorLinePen property (see Example 4).
By default, cards will not display cells that do not contain content. To display all the cells in a card, regardless of if they contain content or not, set the HideEmptyCells property to false.

Headers and Footers

Views define their associated grid's fixed header and fixed footer sections, which are non-scrollable regions usually located at the top and bottom of a grid, and its header and footer sections, which are scrollable regions usually located, respectively, beneath the fixed header and above the fixed footer sections (see Example 1).

By default, a grid will have a HierarhicalGroupByControl and ColumnManagerRow in its fixed header section. In XAML, the content of a header, footer, fixed header, and footer sections can be cleared by setting the UseDefaultHeadersFooters property of a view to false (see Example 2). If left to true, any items that are added to a header or footer section will be added after the default headers and footers.

Setting the UseDefaultHeadersFooters property to false will exclude the default header and footer items from all header and footer sections.
In code, the collections can be cleared by calling the Clear method.

Examples

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.

Example 1: Adding an InsertionRow to the fixed headers

The following example demonstrates how to add an InsertionRow to the fixed header section of a grid. 

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:TableView>

           <xcdg:TableView.FixedHeaders>
              <DataTemplate>
                 <xcdg:InsertionRow/>
              </DataTemplate>
           </xcdg:TableView.FixedHeaders>
         </xcdg:TableView>
      </xcdg:DataGridControl.View>
   </xcdg:DataGridControl>
</Grid>

Example 2: Clearing a fixed header section

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;

Example 3: Changing the main (primary) column

The following example demonstrates how to set the ShipName column as a grid's main column. 

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}}"
                         View="CardView">
      <xcdg:DataGridControl.Columns>
        <xcdg:Column FieldName="ShipName" IsMainColumn="True"/>
      </xcdg:DataGridControl.Columns>
   </xcdg:DataGridControl>
</Grid>
VB.NET
Copy Code 
dataGridControl.Columns( "ShipName" ).IsMainColumn = True
C#
Copy Code 
dataGridControl.Columns[ "ShipName" ].IsMainColumn = true;

Example 4: Adding separator lines

The following examples demonstrates how to add separator lines between card "columns".

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>

           <xcdg:CardView.SeparatorLinePen>
             <Pen Thickness="1.5" Brush="Orange"
                  DashStyle="{x:Static DashStyles.DashDotDot}"/>
           </xcdg:CardView.SeparatorLinePen>
         </xcdg:CardView>
      </xcdg:DataGridControl.View>
   </xcdg:DataGridControl>
</Grid>
VB.NET
Copy Code 
Dim pen As New Pen()
pen.Thickness = 1.5
pen.Brush = Brushes.Orange
pen.DashStyle = DashStyles.DashDotDot

Dim view As New CardView()
view.SeparatorLinePen = pen

dataGridControl.View = view
C#
Copy Code 
Pen pen = new Pen();
pen.Thickness = 1.5;
pen.Brush = Brushes.Orange;
pen.DashStyle = DashStyles.DashDotDot;

CardView view = new CardView();
view.SeparatorLinePen = pen;

dataGridControl.View = view;

 

Example 5: Recreating the default card-view header

The following example demonstrates how to recreate the default card-view header, which contains a ColumnManagerRow to the right of a GroupByControl.

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: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"/>
           </DockPanel>
