Binding to a LINQ query (XML)

In This Topic

The following example demonstrates how to bind a grid to an XML query on an XDocument that loads the XML version of the Orders table of the Northwind database.

The content of the resulting grid will not be editable.

XAML	Copy Code
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"> <Grid.Resources> <xcdg:DataGridCollectionViewSource x:Key="cvs_orders" Source="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}}, Path=XmlData}"/> </Grid.Resources> <xcdg:DataGridControl x:Name="OrdersGrid" ItemsSource="{Binding Source={StaticResource cvs_orders}}"/> </Grid>

XAML

Copy Code

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">
  <Grid.Resources>
    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"
                    Source="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}},
                                     Path=XmlData}"/>
  </Grid.Resources>
 
  <xcdg:DataGridControl x:Name="OrdersGrid"
                       ItemsSource="{Binding Source={StaticResource cvs_orders}}"/>
</Grid>

The following code provides the implementation for the XmlData property, which returns the query result.

VB.NET	Copy Code
Public ReadOnly Property XmlData() As IEnumerable Get Dim document As XDocument = App.NorthwindDocument Dim data As IEnumerable = From order In document.Element("dataroot").Descendants("Orders") _ Select New With {.ShipCountry = order.Element("ShipCountry").Value, _ .ShipCity = order.Element("ShipCity").Value, _ .ShipAddress = order.Element("ShipAddress").Value, _ .ShipName = order.Element("ShipName").Value, _ .Freight = order.Element("Freight").Value} Return data End Get End Property

VB.NET

Copy Code

Public ReadOnly Property XmlData() As IEnumerable
  Get
    Dim document As XDocument = App.NorthwindDocument
    Dim data As IEnumerable = From order In document.Element("dataroot").Descendants("Orders") _
                              Select New With {.ShipCountry = order.Element("ShipCountry").Value, _
                                .ShipCity = order.Element("ShipCity").Value, _
                                .ShipAddress = order.Element("ShipAddress").Value, _
                                .ShipName = order.Element("ShipName").Value, _
                                .Freight = order.Element("Freight").Value}
    Return data
  End Get
End Property

C#	Copy Code
public IEnumerable XmlData { get { XDocument document = App.NorthwindDocument; IEnumerable data = from order in document.Element( "dataroot" ).Descendants( "Orders" ) select new { ShipCountry = order.Element( "ShipCountry" ).Value, ShipCity = order.Element( "ShipCity" ).Value, ShipAddress = order.Element( "ShipAddress" ).Value, ShipName = order.Element( "ShipName" ).Value, ShipVia = order.Element( "ShipVia" ).Value, Freight = order.Element( "Freight" ).Value }; return data; } }

Copy Code

public IEnumerable XmlData
{
 get
 {
   XDocument document = App.NorthwindDocument;
   IEnumerable data = from order in document.Element( "dataroot" ).Descendants( "Orders" )
                      select new
                      {
                        ShipCountry = order.Element( "ShipCountry" ).Value,
                        ShipCity = order.Element( "ShipCity" ).Value,
                        ShipAddress = order.Element( "ShipAddress" ).Value,
                        ShipName = order.Element( "ShipName" ).Value,
                        ShipVia = order.Element( "ShipVia" ).Value,
                        Freight = order.Element( "Freight" ).Value
                      };
   return data;
 }
}
