Question

我无法绑定全景标题。任何想法怎么样？其他绑定工作正常。

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

.cs文件

await bookdetailsvm.GetBookDetails(Convert.ToInt64(bookid));
ContentPanel.DataContext= bookdetailsvm.booksdetailsObject;  returns Books object

书籍对象

 public class Books : INotifyPropertyChanged
{
    private long _BookId = 0;
    public long BookId
    {
        get
        {
            return _BookId;
        }
        set
        {
            _BookId = value;
            RaisePropertyChanged("BookId");
        }
    }

    private string _ISBN = string.Empty;
    public string ISBN
    {
        get
        {
            if (string.IsNullOrEmpty(_ISBN))
            {
                return "No ISBN found";
            }
            else
            {
                return _ISBN;

            }
        }
        set
        {
            _ISBN = value;
            RaisePropertyChanged("ISBN");
        }
    }

    private string _BookTitle = string.Empty;
    public string BookTitle
    {
        get
        {
            if (_BookTitle.Length > 35)
            {
              return _BookTitle.Substring(0, 35) + "...";
           }
            else
                return _BookTitle;
        }
        set
        {
            _BookTitle = value;
        }
    }

Answer 1

它不起作用，因为标题没有绑定。

正确的语法是：

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

Answer 2

似乎其他人也有同样的问题;也许你可以尝试没有TitleTemplate？
