【WPF】WPF通过RelativeSource绑定父控件的属性

1.后台代码实现绑定父控件的属性

RelativeSource rs = new RelativeSource(RelativeSourceMode.FindAncestor);  
//设定为离自己控件最近的第一层父控件  
 rs.AncestorLevel = 1;  
//设定父控件为Gird类型
 rs.AncestorType = typeof(Grid);  
//绑定源为Grid的名称  
 Binding binding = new Binding("Name") { RelativeSource=rs};  
//将绑定的源放在文本显示内容中  
 this.textBox1.SetBinding(TextBox.TextProperty, binding);  

2.前台xaml实现绑定父控件的属性

<TextBox x:Name="textBox1" FontSize="24" Margin="10" Text="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type Grid},AncestorLevel=1},Path=Name}"/>
