FlowDocumentReader.Selection Property

Gets the selected content of the FlowDocumentReader.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public TextSelection Selection { get; }
You cannot set this property in XAML.

Property Value

Type: System.Windows.Documents.TextSelection
The selected content of the FlowDocumentReader.

Selection is introduced in the .NET Framework version 3.5. For more information, see .NET Framework 3.5 Architecture.

The following example shows how to get the text that a user has selected in the FlowDocumentReader.

    <Button Content="Show Selection" Click="ShowSelection_Click"/>
    <FlowDocumentReader Name="flowdocReader1"
        <FlowDocument ColumnWidth="400" 
            <Section FontSize="12">
                    <Bold>Neptune</Bold> (planet), major planet in the solar system, eighth planet
                    from the Sun and fourth largest in diameter.  Neptune maintains an almost constant
                    distance, about 4,490 million km (about 2,790 million mi), from the Sun.  Neptune
                    revolves outside the orbit of Uranus and for most of its orbit moves inside the
                    elliptical path of the outermost planet Pluto (see Solar System). Every 248 years,
                    Pluto’s elliptical orbit brings the planet inside Neptune’s nearly circular orbit
                    for about 20 years, temporarily making Neptune the farthest planet from the Sun.
                    The last time Pluto’s orbit brought it inside Neptune’s orbit was in 1979. In
                    1999 Pluto’s orbit carried it back outside Neptune’s orbit.
                    Astronomers believe Neptune has an inner rocky core that is surrounded by a vast
                    ocean of water mixed with rocky material. From the inner core, this ocean extends
                    upward until it meets a gaseous atmosphere of hydrogen, helium, and trace amounts
                    of methane. Neptune has four rings and 11 known moons. Even though Neptune's volume
                    is 72 times Earth’s volume, its mass is only 17.15 times Earth’s mass. Because of
                    its size, scientists classify Neptune—along with Jupiter, Saturn, and Uranus—as
                    one of the giant or Jovian planets (so-called because they resemble Jupiter).
                    Mathematical theories of astronomy led to the discovery of Neptune. To account for
                    wobbles in the orbit of the planet Uranus, British astronomer John Couch Adams and
                    French astronomer Urbain Jean Joseph Leverrier independently calculated the existence
                    and position of a new planet in 1845 and 1846, respectively. They theorized that the
                    gravitational attraction of this planet for Uranus was causing the wobbles in Uranus’s
                    orbit. Using information from Leverrier, German astronomer Johann Gottfried Galle first
                    observed the planet in 1846.
