Any way to make a WPF textblock selectable?

Can I make a textblock selectable in WPF application so that a user can copy it.

You could just make it into a TextBox that’s Read Only which just looks like a TextBlock, kind of like;

<Style x:Key="ReadOnlyTextBox" TargetType="TextBox">
   <Setter Property="IsReadOnly" Value="True" />
   <Setter Property="Padding" Value="5"/>
   <Setter Property="Margin" Value="0"/>
   <Setter Property="Background" Value="Transparent"/>
   <Setter Property="BorderBrush" Value="Transparent"/>
   <Setter Property="BorderThickness" Value="0"/>
   <Setter Property="IsTabStop" Value="False"/>
   <Setter Property="HorizontalScrollBarVisibility" Value="Disabled"/>
   <Setter Property="VerticalScrollBarVisibility" Value="Disabled"/>
   <Setter Property="Template">
      <Setter.Value>
         <ControlTemplate TargetType="TextBox">
            <Grid x:Name="RootElement">
               <ScrollViewer x:Name="ContentElement"
                             Margin="{TemplateBinding Margin}"
                             Background="{TemplateBinding Background}"
                             BorderBrush="{TemplateBinding BorderBrush}"
                             BorderThickness="{TemplateBinding BorderThickness}"
                             IsTabStop="{TemplateBinding IsTabStop}"
                             Padding="{TemplateBinding Padding}" 
                             HorizontalScrollBarVisibility="{TemplateBinding HorizontalScrollBarVisibility}"
                             VerticalScrollBarVisibility="{TemplateBinding VerticalScrollBarVisibility}"/>
            </Grid>
         </ControlTemplate>
      </Setter.Value>
   </Setter>
</Style>

The ScrollViewer ContentElement would be in a TextBox by default, you could substitute for a ContentPresenter instead if you like also.

Then put it into effect;

<TextBox Text="Blah Blah Blah you can copy me!" Style="{StaticResource ReadOnlyTextBox}"/>

Hope this helps!

ADDENDUM: As @doodleus pointed out in the comments. Template binding the Content Property within the template may be necessary. As “ContentElement” is a named part of the Silverlight TextBox control. One of the little nuance differences to watch for in the different xaml Variants. I must not have paid attention to the Tags when I originally created the example. So kudos to him for correcting me.
