You can add any sort of arbitrary content to a C1Book control. This includes text, images, layout panels, and other standard and 3rd-party controls. In this example, you'll add a TextBlock control to a C1Book control, but you can customize the steps to add other types of content instead.

In XAML

For example, to add a TextBlock control to the book add <TextBlock Text="Hello World!"/> within the <Extended:C1Book> tag so that it appears similar to the following:

<Extended:C1Book Name="c1book1" Height="300" Width="450">
    <TextBlock Text="Hello World!"/>
</Extended:C1Book>

In Code

For example, to add a TextBlock control to the book, add code to the page's constructor so it appears like the following:

Public Sub New()
    InitializeComponent()
Dim c1book1 as New C1Book
    c1book1.Height = 300
    c1book1.Width = 450
    Grid1.Children.Add(c1book1)
    Dim txt1 as New TextBlock
    txt1.Text = "Hello World!"
    c1book1.Items.Add(txt1)
End Sub

public MainPage()
{
    this.InitializeComponent();
    C1Book c1book1 = new C1Book();
    c1book1.Height = 300;
    c1book1.Width = 450;
    Grid1.Children.Add(c1book1);

    TextBlock txt1 = new TextBlock();
    txt1.Text = "Hello World!";
    c1book1.Items.Add(txt1);
}

What You've Accomplished

You've added a control to the C1Book control. Run the application and observe that the TextBlock control has been added to the C1Book control. You can similarly add other content and controls.
