# How to: Detect When the Enter Key Pressed
|
|
This example shows how to detect when the <xref:System.Windows.Input.Key.Enter> key is pressed on the keyboard.
|
|
|
|
This example consists of a [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] file and a code-behind file.
|
|
|
|
## Example
|
|
When the user presses the <xref:System.Windows.Input.Key.Enter> key in the <xref:System.Windows.Controls.TextBox>, the input in the text box appears in another area of the [!INCLUDE[TLA#tla_ui](../../../includes/tlasharptla-ui-md.md)].
|
|
|
|
The following XAML creates the user interface, which consists of a <xref:System.Windows.Controls.StackPanel>, a <xref:System.Windows.Controls.TextBlock>, and a <xref:System.Windows.Controls.TextBox>.
|
|
|
|
[!code-xaml[keydown#KeyDownUI](~/samples/snippets/csharp/VS_Snippets_Wpf/KeyDown/CSharp/Window1.xaml#keydownui)]
|
|
|
|
The following code behind creates the <xref:System.Windows.UIElement.KeyDown> event handler. If the key that is pressed is the <xref:System.Windows.Input.Key.Enter> key, a message is displayed in the <xref:System.Windows.Controls.TextBlock>.
