    public long BookId

            {
              return _BookTitle.Substring(0, 35) + "...";
           }
            else
                return _BookTitle;
        }
        set
        {
            _BookTitle = value;
        }
    }

Answer 1

It does not work because the title is not binded.

The right syntax is:

<phone:Panorama x:Name="pnBookDetails" Title="{Binding BookTitle, Mode=OneWay}">
    <phone:Panorama.TitleTemplate>
    <DataTemplate>
        <TextBlock Text="{Binding }" />
    </DataTemplate>
 </phone:Panorama.TitleTemplate>

Answer 2

It seems other people have had the same issue; maybe you could try without the TitleTemplate?
