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.
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.
