【翻译】WPF中的数据绑定表达式
Self FindAncestor TemplatedParent PreviousData 让我们一个一个详细地探讨一下。 2.1 Self Self用于绑定源和绑定目标相同的场景中。 2.2 FindAncestor 顾名思义，当绑定源是绑定目标的祖先（父级）之一时使用此选项。使用FindAncestor扩展，可以找到任何级别的祖先。 让我们举个例子来更清楚地理解它。 Button></Button> </StackPanel> </Border> </StackPanel> </Grid> 现在，让我们使用FindAncestor ="Vertical"> <Button Height="50" Content="{Binding RelativeSource={RelativeSource <em>FindAncestor</em>

2019-7-24-为啥在Code Behind进行RelativeSource的binding会丢失
{ AncestorType = typeof(Window), Mode = RelativeSourceMode.FindAncestor { AncestorType = typeof(Window), Mode = RelativeSourceMode.FindAncestor 但是此时发现RelativeSource (FindAncestor) requires tree context,我们在查找RelativeSource 时，需要有上下文树，而此时条件不满足，我们的绑定就被延迟了
