# How to: Retrieve a Text Selection
This example shows one way to use the <xref:System.Windows.Controls.TextBox.SelectedText%2A> property to retrieve text that the user has selected in a <xref:System.Windows.Controls.TextBox> control.
## Example
## Define a TextBox control
The following [!INCLUDE[TLA#tla_xaml](../../../includes/tlasharptla-xaml-md.md)] example shows the definition of a <xref:System.Windows.Controls.TextBox> control that contains some text to select, and a <xref:System.Windows.Controls.Button> control with a specified <xref:System.Windows.Controls.Button.OnClick%2A> method.
In this example, a button with an associated <xref:System.Windows.Controls.Primitives.ButtonBase.Click> event handler is used to retrieve the text selection. When the user clicks the button, the <xref:System.Windows.Controls.Button.OnClick%2A> method copies any selected text in the textbox into a string. The particular circumstances by which the text selection is retrieved (clicking a button), as well as the action taken with that selection (copying the text selection to a string), can easily be modified to accommodate a wide variety of scenarios.
[!code-xaml[TextBox_MiscCode#_TextBoxSelectTextXAML](~/samples/snippets/csharp/VS_Snippets_Wpf/TextBox_MiscCode/CSharp/Window1.xaml#_textboxselecttextxaml)]
## Example
## OnClick event handler
The following C# example shows an <xref:System.Windows.Controls.Button.OnClick%2A> event handler for the button defined in the [!INCLUDE[TLA2#tla_xaml](../../../includes/tla2sharptla-xaml-md.md)] for this example.
