    Implements IDisposable

Remarks

<p>
    <xref href="C1.WPF.RichTextBox.C1RichTextViewManager" data-throw-if-not-resolved="false"></xref> must be used in conjunction with <xref href="C1.WPF.RichTextBox.C1RichTextPresenter" data-throw-if-not-resolved="false"></xref> to

display rich text. The Presenters collection contains C1RichTextPresenterSources that connect the C1RichTextViewManager with the C1RichTextPresenters that actually displays the content.

The Presenters collection always contains at least one element, and grows or shrinks when new presenters are needed. This makes it suitable to be used with an ItemsControl to create new presenters as needed. This is a sample of an ItemsControl displaying a Document:

<pre><code class="lang-XAML"><Grid>
    <Grid.Resources>
        <c1rtb:C1RichTextViewManager x:Key="viewManager" Document="{StaticResource someDocument}"/>
    </Grid.Resources>
    <ItemsControl ItemsSource="{Binding Presenters, Source={StaticResource viewManager}}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Border Margin="10" BorderThickness="2" BorderBrush="Red" Padding="2" Height="102">
                    <c1rtb:C1RichTextPresenter Source="{Binding}"/>
                </Border>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Grid></code></pre>
