# 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.
|
|
|
|
## Define a TextBox control
|
|
The following Extensible Application Markup Language (XAML) 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.

## OnClick event handler
|
|
The following C# example shows an <xref:System.Windows.Controls.Button.OnClick%2A> event handler for the button defined in the XAML for this example.
