Provider issue with RadBook and RadRichTextPageView

[Jared]

I'm trying to recreate the integration between the Rich Text Editor and the Radbook control as demonstrated Q3 for 2010 demos. However, when I get to this statement:

                IDocumentFormatProvider provider = DocumentFormatProvidersManager.GetProviderByExtension(extension);

                IDocumentFormatProvider provider = DocumentFormatProvidersManager.GetProviderByExtension(extension);

                IDocumentFormatProvider provider = DocumentFormatProvidersManager.GetProviderByExtension(extension);

IDocumentFormatProvider provider = DocumentFormatProvidersManager.GetProviderByExtension(".docx");

provider is always null. I've looked through the source code with the provided sample and everything is the same, but it just won't find the provider. Is there a step that I need to add to load the providers? or a way to find out which providers exist?

Ok, I got the providers to load but now the document isn't showing up. Based on the integration example, I have the following xaml:

<telerik2:DocumentViewManager x:Name="viewManager"></telerik2:DocumentViewManager>
<DataTemplate x:Key="PageTemplate">

            <Grid Background="White">

                <telerik2:RadRichTextPageView HorizontalAlignment="Center"

                    VerticalAlignment="Center"

                    ViewManager="{Binding ElementName=viewManager}"

                    PageIndex="{Binding Path=PageIndex}"

                    >

                    <telerik2:RadRichTextPageView.RenderTransform>

                        <ScaleTransform ScaleX="0.7" ScaleY="0.7"></ScaleTransform>

                    </telerik2:RadRichTextPageView.RenderTransform>

                </telerik2:RadRichTextPageView>

                <TextBlock Height="30" HorizontalAlignment="Center" VerticalAlignment="Bottom" FontSize="9"

                    Foreground="#5B5B5B" Margin="0,0,0,5" Text="{Binding Path=PageIndexDisplay}" />

            </Grid>

        </DataTemplate>

        <DataTemplate x:Key="ContentTemplate">

            <Grid>

                <telerikNavigation:RadBook x:Name="book" Visibility="Collapsed" RightPageIndex="1"

                                           LeftPageTemplate="{StaticResource PageTemplate}" RightPageTemplate="{StaticResource PageTemplate}">

                </telerikNavigation:RadBook>

        </DataTemplate>

And the following code:

private void LoadDocument(System.ServiceModel.DomainServices.Client.InvokeOperation<byte[]> result)
{
    RadDocument doc;
    byte[] resultFinal;
    resultFinal = result.Value;
    byte[] empty = new byte[0];
        IDocumentFormatProvider provider = new DocxFormatProvider();
        if (provider != null)
        {
            doc = provider.Import(resultFinal);
        }
        else
        {
            MessageBox.Show("Unknown format.");
            return;
        }

        this.book.RightPageIndex = 0;

        this.viewManager.Document = doc;
        bindingSource.Document = doc;
 }

Any thoughts?

static Example()

        {

            ExamplesFormatProvidersManager.RegisterFormatProviders();

        }

        public Example()

        {

            InitializeComponent();

        }

static Example()

        {

            ExamplesFormatProvidersManager.RegisterFormatProviders();

        }

        public Example()

        {

            InitializeComponent();

        }

Turns out I was missing this line:

book.ItemsSource = bindingSource;
