What is DataContext ? How is it used ?

Platform: WPF| Category: DataBinding

Every FrameworkElement can be associated with a DataContext which will be used as the default data source during binding, if no other data source is specified in the binding code. Also, the children of this FrameworkElement auotmatically inherit this setting. This helps having to repeatedly specify this data source as the source of a binding, thereby letting you simplify the binding code.

The following code snippet is an example of implicit datasource using DataContext.


<StackPanel x:Name='Class' DataContext='{StaticResource student}'>
<Label x:Name='studcount' Content='{Binding Path=Count}'/>
<ListBox x:Name='Studname' DisplayMemberPath='Name' ItemsSource='{Binding}'/>
