DataGrid Fundamentals: Views and Themes

The TableView class

The TableView class provides a traditional, non-animated table-view layout for the data items in a grid.

The TableflowView class

The Tableflow™ view is represented by the TableflowView class. Although it also provides a table-view layout, it differs greatly from the TableView class from which it derives. It provides a rich, fluid, and high performance user experience, featuring a capabilities such as inertial smooth scrolling and animated full-column reordering—which mimic the physics of real-life movement. For details on these visual features, see Smooth Scrolling and Other Animated Effects.

Gridlines and Group Levels

The grid lines displayed when a grid is in table-view layout are determined by the VerticalGridLineBrush and HorizontalGridLineBrush properties, in conjunction with the VerticalGridLineThickness and HorizontalGridLineThickness properties (see Example 3). 
The width of the group-level indicators (see Figure 2) can be modified through the GroupLevelIndicatorWidth property. The group-level indicators can be hidden by setting the ShowIndicators attached property of the GroupLevelIndicatorPane to false; however, the space reserved for the indicators in the group-level indicator pane will remain visible and provide the rows with an indentation when they are grouped. To completely remove the group-level indicator pane, a style must be created for GroupLevelIndicatorPane objects and the Visibility property set to Collapsed (see Example 4).
Through the ShowRowSelectorPane property, the row-selector pane (see Figure 3) can be shown or hidden (see Example 3).

Each theme provides an alternate row color, which can be activated by setting the TableView's IsAlternatingRowStyleEnabled property to true. By default, alternating row styles are not enabled.

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.

Fixing Elements (other than columns)

Elements, such as group-by and group-header controls, can also be fixed to prevent them from scrolling with the grid content through the use of the CanScrollHorizontally attached property. The CanScrollHorizontally attached property has been set to false for the GroupByControl, HierarchicalGroupByControl,  GroupHeaderControl, and RowSelectorPane in each table-view theme. If these elements are added manually to a fixed section of a grid in table-view layout, only the CanScrollHorizontally property of the group-by control must be explicitly set to false (see Example 6); the group-header control and row-selector pane, by default, already have their CanScrollHorizontally property set to false.

Rows—regardless of their type—will ignore the CanScrollHorizontally property and scroll with the grid content.

Column Virtualization

In addition to the built-in container recycling, which applies to all views, the TableView class provides column virtualization, meaning that columns and cells that are not visible in the viewport are not created until they are brought into the viewport or accessed. If required, column virtualization can be disabled by setting the IsColumnVirtualizationEnabled property to false (by default, true).

By default, a grid will take all the room that it requires; therefore, if it is not given a size constraint, such as when it is placed in a StackPanel, and a large amount of data items are present, UI virtualization will be lost—resulting in a significant loss in performance. To preserve virtualization when a grid is in a StackPanel, the MaxWidth and MaxHeight properties (or Width and Height) must be used to constrain the grid. As an alternative, a DockPanel or Grid can be used as both impose size constraints on their child elements.

Using column stretching in combination with column virtualization may result in unpredictable behaviors.

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: 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 2: Adding vertical and horizontal grid lines

The following example demonstrates how to add vertical and horizontal grid lines to a grid in table-view layout. A style for the ColumnManagerRow objects has been added to the resources to remove the horizontal grid line drawn above the column-manager row in the fixed headers.

XAML
Copy Code 
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">

   <Grid.Resources>

      <Style TargetType="{x:Type xcdg:ColumnManagerRow}">

         <Setter Property="BorderThickness" Value="0"/>

      </Style>

      <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 HorizontalGridLineThickness="1" VerticalGridLineThickness="1">

           <xcdg:TableView.HorizontalGridLineBrush>

              <SolidColorBrush Color="Orange"/>

           </xcdg:TableView.HorizontalGridLineBrush>

           <xcdg:TableView.VerticalGridLineBrush>

              <SolidColorBrush Color="Orange"/>

           </xcdg:TableView.VerticalGridLineBrush>

        </xcdg:TableView> 

      </xcdg:DataGridControl.View>

   </xcdg:DataGridControl>

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

view.HorizontalGridLineThickness = 1

view.VerticalGridLineThickness = 1



view.HorizontalGridLineBrush = Brushes.Orange

view.VerticalGridLineBrush = Brushes.Orange



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

view.HorizontalGridLineThickness = 1;

view.VerticalGridLineThickness = 1;



view.HorizontalGridLineBrush = Brushes.Orange;

view.VerticalGridLineBrush = Brushes.Orange;



dataGridControl.View = view;

Example 3: Hiding the group-level indicator pane

The following example demonstrates how to hide the group-level indicator pane by creating a style which sets the Visibility property of GroupLevelIndicatorPane objects to Collapsed.

XAML
Copy Code 
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">

  <Grid.Resources>

     <Style TargetType="{x:Type xcdg:GroupLevelIndicatorPane}">

       <Setter Property="Visibility" Value="Collapsed"/>

     </Style>

    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"

                                    Source="{Binding Source={x:Static Application.Current},

                                                      Path=Orders}">

      <xcdg:DataGridCollectionViewSource.GroupDescriptions>

        <xcdg:DataGridGroupDescription PropertyName="ShipCountry"/>

      </xcdg:DataGridCollectionViewSource.GroupDescriptions>

    </xcdg:DataGridCollectionViewSource>

  </Grid.Resources>

  <xcdg:DataGridControl x:Name="OrdersGrid"

                        ItemsSource="{Binding Source={StaticResource cvs_orders}}"/>

</Grid>

Example 4: Hiding the row-selector pane

The following example demonstrates how to hide the row-selector pane. 

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 ShowRowSelectorPane="False"/>

      </xcdg:DataGridControl.View>

   </xcdg:DataGridControl>

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

view.ShowRowSelectorPane = False

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

view.ShowRowSelectorPane = false;

dataGridControl.View = view;

Example 6: Allowing horizontal scrolling

The following example demonstrates how to prevent horizontal scrolling of the group-by control in the fixed header section.

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}">

      <xcdg:DataGridCollectionViewSource.GroupDescriptions>

        <xcdg:DataGridGroupDescription PropertyName="ShipCountry"/>

      </xcdg:DataGridCollectionViewSource.GroupDescriptions>

    </xcdg:DataGridCollectionViewSource>

  </Grid.Resources>



  <xcdg:DataGridControl x:Name="OrdersGrid"

                        ItemsSource="{Binding Source={StaticResource cvs_orders}}">

    <xcdg:DataGridControl.View>

      <xcdg:TableView UseDefaultHeadersFooters="False">

        <xcdg:TableView.FixedHeaders>

          <DataTemplate>

            <xcdg:GroupByControl xcdg:TableView.CanScrollHorizontally="True"/>

          </DataTemplate> 

          <DataTemplate>

            <xcdg:ColumnManagerRow/>

          </DataTemplate>

        </xcdg:TableView.FixedHeaders>

      </xcdg:TableView>

    </xcdg:DataGridControl.View>

  </xcdg:DataGridControl>

</Grid>

Example 7: Using routed view properties

The following example demonstrates how to set routed view properties on detail configurations to change the width of their detail indicators as well as to fix columns and remove the fixed-column splitter.

XAML
Copy Code 
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"

      xmlns:local="clr-namespace:Xceed.Wpf.Documentation">

  <Grid.Resources>

     <xcdg:DataGridCollectionViewSource x:Key="cvs_employees"

                                        Source="{Binding Source={x:Static Application.Current},

                                                    Path=Employees}" />

  </Grid.Resources>

  <xcdg:DataGridControl x:Name="EmployeesGrid"

                      ItemsSource="{Binding Source={StaticResource cvs_employees}}"

                      AutoCreateDetailConfigurations="True">

     <xcdg:DataGridControl.Columns>

        <xcdg:Column FieldName="Photo"

                     Visible="False" />

     </xcdg:DataGridControl.Columns>

     <xcdg:DataGridControl.DetailConfigurations>

        <xcdg:DetailConfiguration RelationName="Employee_Orders"

                                  Title="Employee Orders"

                                  xcdg:TableView.DetailIndicatorWidth="50"

              <xcdg:DetailConfiguration RelationName="Order_OrderDetails"

                                        Title="Order Details"

                                        xcdg:TableView.ShowFixedColumnSplitter="False"

                                        xcdg:TableView.DetailIndicatorWidth="50"/>

           </xcdg:DetailConfiguration.DetailConfigurations>

        </xcdg:DetailConfiguration>

detailConfiguration.Title = "Employee Orders"

detailConfiguration.Columns( "EmployeeID" ).Visible = False

detailConfiguration.SetValue( TableView.DetailIndicatorWidthProperty, 50 )

detailConfiguration.SetValue( TableView.FixedColumnCountProperty, 2 )

Dim childDetailConfiguration As New DetailConfiguration()

childDetailConfiguration.RelationName = "Order_OrderDetails"

childDetailConfiguration.Title = "Order Details"

childDetailConfiguration.SetValue( TableView.ShowFixedColumnSplitterProperty, false )

childDetailConfiguration.SetValue( TableView.DetailIndicatorWidthProperty, 50 )

detailConfiguration.DetailConfigurations.Add( childDetailConfiguration )

dataGridControl.DetailConfigurations.Add( detailConfiguration )
