Silverlight，通过UserControls的TemplateBindings的路径

Question

我有一个带有TextBox（Binding TextBoxText）的MainPage.xaml和一些嵌套的UserControls，它们都带有一个带有TemplateBinding/Binding的TextBox（4 TextBoxes）。
我想在每个框中都有相同的文本，当我在某处更改文本时。

解决办法：Link

我能做什么来同步所有文本？

谢谢！

MainPage.xaml中（TextBoxText是一个，我喜欢到处显示）

<myContDll:DefaultContainerTemplate Caption="NewCaption"> 
    <StackPanel x:Name="myStackPanel"> 
     <sdk:Label Content="Binding TextBoxText of MainPage"/> 
     <TextBox Text="{Binding TextBoxText}"/> 
     <myDll:MyButtonControl x:Name="ButtonControl" Count="44" 
          Button3Caption="NewButton3" 
          Button3Visibility="Visible" 
          DisplayText="Form2Text2" 
          TextBoxText="{Binding TextBoxText}"/> 
    </StackPanel> 
</myContDll:DefaultContainerTemplate> 

Generic.xaml：

<Style TargetType="local:MyButtonControl"> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="local:MyButtonControl"> 
       <StackPanel> 
        <sdk:Label Content="inner control test"/> 
        <sdk:Label Content="TemplateBinding TextBoxText of MyButtonControl"/> 
        <TextBox Text="{TemplateBinding TextBoxText}"/> 
        <Button Content="{TemplateBinding Button3Caption}" Visibility="{TemplateBinding Button3Visibility}" x:Name="Button3"/> 
        <local:CountDisplayControl x:Name="Control1" TextBoxText="{TemplateBinding TextBoxText}" Visibility="{TemplateBinding VisibilityText1}" Count="{TemplateBinding Count}" DisplayText="{TemplateBinding DisplayText1}"/> 
        <local:CountDisplayControl2 x:Name="Control2" TextBoxText="{TemplateBinding TextBoxText}" Visibility="{TemplateBinding VisibilityText2}" Count="{TemplateBinding Count}" DisplayText="{TemplateBinding DisplayText2}"/> 
        <local:CountDisplayUserControl TextBoxText="{TemplateBinding TextBoxText}"/> 
       </StackPanel> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 
<Style TargetType="local:CountDisplayControl"> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="local:CountDisplayControl"> 
       <Border Background="{TemplateBinding Background}" 
         BorderBrush="{TemplateBinding BorderBrush}" 
         BorderThickness="{TemplateBinding BorderThickness}"> 
        <StackPanel> 
         <sdk:Label Content="Control1"/> 
         <sdk:Label Content="{TemplateBinding Count}"/> 
         <sdk:Label x:Name="labelText" Content="{TemplateBinding Text}"/> 
         <sdk:Label Content="TemplateBinding TextBoxText of CountDisplayControl"/> 
         <TextBox Text="{TemplateBinding TextBoxText}"/> 
        </StackPanel> 
       </Border> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style> 
<Style TargetType="local:CountDisplayControl2"> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="local:CountDisplayControl2"> 
       <Border Background="{TemplateBinding Background}" 
         BorderBrush="{TemplateBinding BorderBrush}" 
         BorderThickness="{TemplateBinding BorderThickness}"> 
        <StackPanel> 
         <sdk:Label Content="Control2"/> 
         <sdk:Label Content="{TemplateBinding Count}"/> 
         <sdk:Label x:Name="labelText" Content="{TemplateBinding Text}"/> 
         <sdk:Label Content="TemplateBinding TextBoxText of CountDisplayControl2"/> 
         <TextBox Text="{TemplateBinding TextBoxText}"/> 
        </StackPanel> 
       </Border> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style>

尝试设置你的BindingMode到TwoWay结合：

<myContDll:DefaultContainerTemplate Caption="NewCaption"> 
    <StackPanel x:Name="myStackPanel"> 
     <sdk:Label Content="Binding TextBoxText of MainPage"/> 
     <TextBox Text="{Binding TextBoxText, Mode=TwoWay}"/> 
     <myDll:MyButtonControl x:Name="ButtonControl" Count="44" 
        Button3Caption="NewButton3" 
        Button3Visibility="Visible" 
        DisplayText="Form2Text2" 
        TextBoxText="{Binding TextBoxText, Mode=TwoWay}"/> 
    </StackPanel> 
</myContDll:DefaultContainerTemplate>
