Question

在Silverlight 4中会有RelativeSource FindAncestor,AncestorType ......吗？

Answer 1

在Silverlight 4中,RelativeSource属性Binding仍然只支持"Self"和"TemplatedParent",Silverlight 3在此区域没有变化.

Answer 2

RelativeSource AncestorType Silverlight 5支持,现已上市.

<TextBlock Text="{Binding Name}" 
           FontSize="{Binding DataContext.CustomFontSize, 
               RelativeSource={RelativeSource AncestorType=UserControl}}"
/>
