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 Extensible Application Markup Language (XAML) 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 user interface (UI).
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-xamlkeydown#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.
