Property Value

Type: System.ComponentModel.SortDescriptionCollection
A collection of SortDescription objects that describe how the items in the collection are sorted in the view.

This property is forwarded to any collection view created from the current Source.

The following code example demonstrates the use of this property in XAML to apply sorting to a data source. The data is also defined in XAML to enable you to see the effects of the CollectionViewSource in the Silverlight Designer in Visual Studio 2010.

This example uses the Customer and CustomerCollection classes defined in Walkthrough: Using Sample Data in the Silverlight Designer. The walkthrough also describes how to use design-time attributes to display sample data in the Silverlight Designer.
