自定义控制

Question

我与数据绑定在一个自定义的控制

我我自定义的控制范围内得到了一些性质stuggeling与属性中绑定到一个集合。

public static DependencyProperty TitleProperty; 
public static DependencyProperty PageDictionaryProperty; 

public string Title 
{ 
    get 
    { 
     return (string)base.GetValue(TitleProperty); 
    } 
    set 
    { 
     base.SetValue(TitleProperty, value); 

    } 

} 

public Innax.ManualParts.PageDictionary PageDictionary 
{ 
    get 
    { 
     return (Innax.ManualParts.PageDictionary)base.GetValue(PageDictionaryProperty); 
    } 
    set 
    { 
     base.SetValue(PageDictionaryProperty, value); 
    } 

} 

绑定到表不是问题。这工作正常

但现在我想绑定到pageDictionary中的关键字属性。

public class PageDictionary 
{ 
    //some other properties.... 
    public List<string> Keywords 
    { 
     get 
     { 
      return GetKeyWords(); 
     } 
    } 
} 

这是XAML文件。

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             <Button Height="Auto" HorizontalContentAlignment="Stretch" Content="knoppie" /> 
            </ListView> 

            <ItemsControl ItemContainerStyle="{StaticResource alternatingWithTriggers}" 
              AlternationCount="2" 
              x:Name="RelatedItemsControl" 
              Grid.Row="1" 
              Grid.Column="0" 
              ItemsSource="{TemplateBinding PageDictionary}" 
              ItemTemplate="{StaticResource HelpTopicLineTemplate}"> 
            </ItemsControl> 

           </StackPanel> 
          </Grid> 
         </Grid> 
        </Border> 
       </ControlTemplate> 
      </Setter.Value> 
     </Setter> 

    </Style> 
</ResourceDictionary> 

如果有人可以帮我这个...

在你的情况PageDirectory类需要实现INotifyPropertyChanged接口。每次关键字里面也改变了你需要引发PropertyChanged事件是这样的：

if (PropertyChanged != null) 
PropertyChanged(this, new PropertyChangedEventArgs("Keywords")) 

捆扎带届时将有鉴于这样的：

{Binding Keywords, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type local:PageDictionary}}} 

如果当地的命名空间中声明上在XAML为访问PageDictionary类型。
