我有一个包含 DocumentViewer 控件的视图，并且我有另一个类，该类具有公开 FixedDocumentSequence 并实现 INotifyPropertyChanged 的​​属性。我正在尝试将 documentviewer 的文档属性数据绑定到 FixedDocumentSequence 属性，当我运行它时，documentviewer 不会加载 FixedDocumentSequence。视图中的所有其他绑定都在工作，但不是这个。

以下是任何帮助的代码片段，希望这是我忘记的一些微不足道的事情。

public class Generator : INotifyPropertyChanged
{
    private const string _fixedDocumentSequencePropertyName = "Fixed Document Sequence";


    private FixedDocumentSequence _fixedDocumentSequence;
    public FixedDocumentSequence FixedDocumentSeq
    {
        get { return _fixedDocumentSequence; }
        private set
        {
            this._fixedDocumentSequence = value;
            onPropertyChanged(_fixedDocumentSequencePropertyName);
        }
    }

    #region INotifyPropertyChanged Members

    public event PropertyChangedEventHandler PropertyChanged;

    private void onPropertyChanged(string propertyName)
    {
        if (this.PropertyChanged != null)
        {
            this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }

    }

    #endregion
}

这是相关的xaml：

<Window.Resources>
    <ResourceDictionary>
    <generator:Generator x:Key="gen"/>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Resources/StyleDictionary.xaml"/>
            <ResourceDictionary Source="Resources/AnimationDictionary.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

<Grid DockPanel.Dock="Top" 
          Margin="0,0,0,20" DataContext="{Binding Source={StaticResource gen}}">
        <DocumentViewer Name="documentViewer1" Margin="6,180,8,0" Visibility="Visible" Document="{Binding Path=FixedDocumentSeq, Mode=OneWay}"/>
</Grid>

被调用了吗？尝试返回 IDocumentPaginatorSource。您应该能够将 _fixedDocumentSequence 转换为 IDocumentPaginatorSource。
