## Example
The following example shows how to create an existing `Customer` object that contains changes to be saved to the data service. The object is attached to the context and the <xref:System.Data.Services.Client.DataServiceContext.UpdateObject%2A> method is called to mark the attached object as <xref:System.Data.Services.Client.EntityStates.Modified> before the <xref:System.Data.Services.Client.DataServiceContext.SaveChanges%2A> method is called.

## Example
The following example is from the code-behind page for an Extensible Application Markup Language (XAML) page that defines the `SalesOrders` window in WPF. When the window is loaded, a <xref:System.Data.Services.Client.DataServiceCollection%601> is created based on the result of a query that returns customers, filtered by country. All of the pages of this paged result are loaded, along with the related orders, and are bound to the <xref:System.Windows.FrameworkElement.DataContext%2A> property of the <xref:System.Windows.Controls.StackPanel> that is the root layout control for the WPF window.

## Binding Data to Windows Presentation Foundation Elements
Because the <xref:System.Data.Services.Client.DataServiceCollection%601> class inherits from the <xref:System.Collections.ObjectModel.ObservableCollection%601> class, you can bind objects to an element, or control, in a Windows Presentation Foundation (WPF) application as you would when using the <xref:System.Collections.ObjectModel.ObservableCollection%601> class for binding. For more information, see [Data Binding (Windows Presentation Foundation)](../../../../docs/framework/wpf/data/data-binding-wpf.md). One way to bind data service data to WPF controls is to set the `DataContext` property of the element to the instance of the <xref:System.Data.Services.Client.DataServiceCollection%601> class that contains the query result. In this case, you use the <xref:System.Windows.Controls.ItemsControl.ItemsSource%2A> property to set the object source for the control. Use the <xref:System.Windows.Controls.ItemsControl.DisplayMemberPath%2A> property to specify which property of the bound object to display. If you are binding an element to a related object that is returned by a navigation property, include the path in the binding defined for the <xref:System.Windows.Controls.ItemsControl.ItemsSource%2A> property. This path is relative to the root object set by the <xref:System.Windows.FrameworkElement.DataContext%2A> property of the parent control. The following example sets the <xref:System.Windows.FrameworkElement.DataContext%2A> property of a <xref:System.Windows.Controls.StackPanel> element to bind the parent control to an <xref:System.Data.Services.Client.DataServiceCollection%601> of customer objects:

When you use the **Add Service Reference** dialog to generate the client data service classes, a project data source is also created that is based on the generated <xref:System.Data.Services.Client.DataServiceContext>. With this data source, you can create UI elements or controls that display data from the data service simply by dragging items from the **Data Sources** window onto the designer. These items become elements in the application UI that are bound to the data source. For more information, see [How to: Bind Data Using a Project Data Source](../../../../docs/framework/data/wcf/how-to-bind-data-using-a-project-data-source-wcf-data-services.md).

## Binding Paged Data
A data service can be configured to limit the amount of queried data that is returned in a single response message. For more information, see [Configuring the Data Service](../../../../docs/framework/data/wcf/configuring-the-data-service-wcf-data-services.md). When the data service is paging response data, each response contains a link that is used to return the next page of results. For more information, see [Loading Deferred Content](../../../../docs/framework/data/wcf/loading-deferred-content-wcf-data-services.md). In this case, you must explicitly load pages by calling the <xref:System.Data.Services.Client.DataServiceCollection%601.Load%2A> method on the <xref:System.Data.Services.Client.DataServiceCollection%601> by passing the URI obtained from the <xref:System.Data.Services.Client.DataServiceQueryContinuation.NextLinkUri%2A> property, as in the following example:

In the following example, the <xref:System.Collections.Specialized.NotifyCollectionChangedAction.Remove> action is customized to call the <xref:System.Data.Services.Client.DataServiceContext.DeleteLink%2A> and <xref:System.Data.Services.Client.DataServiceContext.DeleteObject%2A> method to remove `Orders_Details` entities that belong to a deleted `Orders` entity. This custom action is performed because dependent entities are not automatically deleted when the parent entity is deleted.
