How to: Bind to the Results of a LINQ Query
This example demonstrates how to run a LINQ query and then bind to the results.
Example
The following example creates two list boxes. The first list box contains three list items.
[!code-xamlLinqExample#UI]
Selecting an item from the first list box invokes the following event handler. In this example, Tasks is a collection of Task objects. The Task class has a property named Priority. This event handler runs a LINQ query that returns the collection of Task objects that have the selected priority value, and then sets that as the xref:System.Windows.FrameworkElement.DataContext%2A:
[!code-csharpLinqExample#Using] [!code-csharpLinqExample#Tasks] [!code-csharpLinqExample#Handler]
The second list box binds to that collection because its xref:System.Windows.Controls.ItemsControl.ItemsSource%2A value is set to {Binding}. As a result, it displays the returned collection (based on the myTaskTemplate xref:System.Windows.DataTemplate).
