各种情况下 Data Binding 总结

绑定到另一个控件的属性

   
   
   

    
    
    <
    
    
    StackPanel
    
    
    >
    
    
    

    
    
    <
    
    
    TextBox 
    
    
    x:Name
    
    
    ="theTextBox"
    
    
    />
    
    
    

    
    
    <
    
    
    TextBlock 
    
    
    Text
    
    
    ="
    
    
    {Binding Text, ElementName=theTextBox}
    
    
    "
    
    
    />
    
    
    

    
    
    </
    
    
    StackPanel
    
    
    >
   
   
   

上面这个例子，TextBlock的内容绑定了TextBox，当在TextBox里输入文本是，TextBlock也同时显示

绑定到 RelativeSource

    
    
    

     
     
     <
     
     
     ListBox 
     
     
     ItemsSource
     
     
     ="
     
     
     {Binding MyDataSrc}
     
     
     "
     
     
      Width
     
     
     ="200"
     
     
      Padding
     
     
     ="0"
     
     
     >
     
     
     

     
     
     <
     
     
     ListBox.ItemTemplate
     
     
     >
     
     
     

     
     
     <
     
     
     DataTemplate
     
     
     >
     
     
     

     
     
     <
     
     
     Grid 
     
     
     Width
     
     
     ="
     
     
     {Binding Path=ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListBoxItem}}
     
     
     "
     
     
     >
     
     
     

     
     
     <
     
     
     Button 
     
     
     Content
     
     
     ="
     
     
     {Binding}
     
     
     "
     
     
     />
     
     
     

     
     
     </
     
     
     Grid
     
     
     >
     
     
     

     
     
     </
     
     
     DataTemplate
     
     
     >
     
     
     

     
     
     </
     
     
     ListBox.ItemTemplate
     
     
     >
     
     
     

     
     
     </
     
     
     ListBox
     
     
     >
    
    
    

    
    
    

     
     
     {Binding Path=xxx, RelativeSource={RelativeSource Self}}
{Binding Path=xxx, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type typeXXX}}}
{Binding Path=xxx, RelativeSource={RelativeSource TemplatedParent}}
{TemplateBinding Path=xxx}
