2019-7-24-为啥在Code Behind进行RelativeSource的binding会丢失
当我们尝试将一个RelativeSource从xaml转到code behind时，原本好好的binding表达式居然出现binding错误。 UserControl x:Class="WpfApp1.UserControl1"> <Grid> <TextBlock Name="TextBlock" Text="{Binding <em>RelativeSource</em> ={<em>RelativeSource</em> AncestorType=Window},Path=Title}" /> </Grid> </UserControl> <Window x:Class="WpfApp1 ={<em>RelativeSource</em> AncestorType=Window},Path=Title,PresentationTraceSources.TraceLevel=High}" /> </ 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

【翻译】WPF中的数据绑定表达式
DataContext绑定 RelativeSource绑定 集合当前项绑定 1、DataContext绑定 DataContext是一个依赖属性，它是绑定的默认源。 输出 2、RelativeSource 绑定 RelativeSource是一个属性，它用相对关系设置绑定源以绑定目标。此扩展主要用于必须将元素的一个属性绑定到同一元素的另一个属性时。 RelativeSource有四种类型，如下所示。 Self FindAncestor TemplatedParent PreviousData 让我们一个一个详细地探讨一下。 <Grid> <Ellipse Fill="Black" Height="100" Width="{Binding <em>RelativeSource</em>={<em>RelativeSource</em> Self}, Margin="35" Content="{Binding <em>RelativeSource</em>={<em>RelativeSource</em> TemplatedParent},Path=Content
