Examples

The following example shows how to define a ListView control that implements a GridView as its View.

  <ListView ItemsSource="{Binding Source={StaticResource EmployeeData}, 
                         XPath=Employee}">
  <ListView.View>
    <GridView>
      <GridViewColumn Header="First Name" 
                      DisplayMemberBinding="{Binding XPath=FirstName}" />
      <GridViewColumn Header="Last Name" 
                      DisplayMemberBinding="{Binding XPath=LastName}" />
      <GridViewColumn Header="Favorite City"
                      DisplayMemberBinding="{Binding XPath=FavoriteCity}"/>
    </GridView>
  </ListView.View>
</ListView>

Remarks

The GridView class and its supporting classes provide the infrastructure to display data items that are specified for a ListView control in a series of columns. The columns have column headers, which are buttons that are derived from ButtonBase, and you can reorder the columns by using drag-and-drop operations. Note that the columns of a GridView display data and do not provide direct access to the source of the data.

To specify a GridView as the view mode for a ListView, set the View property to a GridView object.

The GridView class is derived from ViewBase. You can define custom views by inheriting from the ViewBase class that provides the supporting elements for a view. For more information, see How to: Create a Custom View Mode for a ListView.

The following illustration shows an example of a ListView that uses a GridView.

ListView with GridView output

The columns in a GridView are defined as GridViewColumn objects. In Extensible Application Markup Language (XAML), you can define GridViewColumn objects as child elements of the GridView. In code, you can add a GridViewColumn to the GridView by using the Columns property and the Add method that is defined for the Collection<T> class. Similarly, you can use other Collection<T> methods such as Remove and Insert to modify the columns in a GridView.

The following example shows how to define the columns of a GridView.


GridView myGridView = new GridView();
myGridView.AllowsColumnReorder = true; 
myGridView.ColumnHeaderToolTip = "Employee Information";

GridViewColumn gvc1 = new GridViewColumn();
gvc1.DisplayMemberBinding = new Binding("FirstName");
gvc1.Header = "FirstName";
gvc1.Width = 100;
myGridView.Columns.Add(gvc1);
GridViewColumn gvc2 = new GridViewColumn();
gvc2.DisplayMemberBinding = new Binding("LastName");
gvc2.Header = "Last Name";
gvc2.Width = 100;
myGridView.Columns.Add(gvc2);
GridViewColumn gvc3 = new GridViewColumn();
gvc3.DisplayMemberBinding = new Binding("EmployeeNumber");
gvc3.Header = "Employee No.";
gvc3.Width = 100;
myGridView.Columns.Add(gvc3);


Dim myGridView As New GridView()
myGridView.AllowsColumnReorder = True
myGridView.ColumnHeaderToolTip = "Employee Information"

Dim gvc1 As New GridViewColumn()
gvc1.DisplayMemberBinding = New Binding("FirstName")
gvc1.Header = "FirstName"
gvc1.Width = 100
myGridView.Columns.Add(gvc1)
Dim gvc2 As New GridViewColumn()
gvc2.DisplayMemberBinding = New Binding("LastName")
gvc2.Header = "Last Name"
gvc2.Width = 100
myGridView.Columns.Add(gvc2)
Dim gvc3 As New GridViewColumn()
gvc3.DisplayMemberBinding = New Binding("EmployeeNumber")
gvc3.Header = "Employee No."
gvc3.Width = 100
myGridView.Columns.Add(gvc3)


<GridView AllowsColumnReorder="true"
          ColumnHeaderToolTip="Employee Information">

  <GridViewColumn DisplayMemberBinding=
                      "{Binding Path=FirstName}" 
                  Header="First Name" Width="100"/>
    
              <GridViewColumn DisplayMemberBinding=
                      "{Binding Path=LastName}" 
                  Width="100">
                  <GridViewColumnHeader>Last Name
                      <GridViewColumnHeader.ContextMenu>
                      <ContextMenu  MenuItem.Click="LastNameCM_Click"  
                                    Name="LastNameCM">
                          <MenuItem Header="Ascending" />
                          <MenuItem Header="Descending" />
                      </ContextMenu>
                      </GridViewColumnHeader.ContextMenu>
                  </GridViewColumnHeader>
              </GridViewColumn>

              <GridViewColumn DisplayMemberBinding=
                      "{Binding Path=EmployeeNumber}" 
                  Header="Employee No." Width="100"/>
</GridView>

To style the rows in a GridView, define a style for the ListViewItem controls in the ListView.

To add visual elements, such as a CheckBox or Button control, to a GridView, use templates or styles. For an example, see How to: Create ListViewItems with a CheckBox.
