This example shows one way to use the property to retrieve text that the user has selected in a TextBox control.
In this example, a button with an associated Click event handler is used to retrieve the text selection. When the user clicks the button, the OnClick 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.
The following C# example shows an OnClick event handler for the button defined in the XAML for this example.
