我有一個視圖,其中包含一個DocumentViewer控件,並且我有另一個具有公開FixedDocumentSequence並實現INotifyPropertyChanged的屬性的類。我試圖將documentviewer的document屬性綁定到FixedDocumentSequence屬性,當我運行它時,documentviewer不會加載FixedDocumentSequence。視圖中的所有其他綁定正在工作,但不是這一個。數據綁定到DocumentViewer.Document屬性
這裏是代碼片段的任何幫助將不勝感激,希望這是我微不足道的僞造。
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
}
,這裏是相關的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>
如果我在get上設置了一個斷點,它會在窗口第一次加載時觸發,但不在之後觸發。我用IDocumentPaginatorSource嘗試過,但沒有運氣,演員的作品,但結果是一樣的。 – jfin3204 2011-12-20 21:04:37
您可以做的另一件事是創建一個帶有catch塊的pass through轉換器,並且有時會發現一個錯誤。你確定文件不只是空白? – Paparazzi 2011-12-20 22:15:42
嘗試調用NotifyPropopertyChanged(「FixedDocumentSeq」);如果get只是在負載上調用,那麼你需要看看set。 – Paparazzi 2011-12-20 22:31:35
