在控件模板中编辑模板绑定

Question

我创建了一个 ControlTemplate 这样的：

<ControlTemplate x:Key="FieldTemplate" TargetType="ContentControl">
  <Border Background="LightGray" >
    <DockPanel >
      <TextBlock DockPanel.Dock="Left" Text="{TemplateBinding c1}" />
      <TextBlock DockPanel.Dock="Left" Text="{TemplateBinding c2}" />
      <TextBox />
    </DockPanel>
  </Border>
</ControlTemplate>

现在我想编辑两个文本块，我该怎么做？我尝试了类似的方法和其他变体，但没有用：

<ContentControl c1="hello" c2="olleh" 
       Template="{StaticResource FieldTemplate}" x:Name="NameControl"/>

A ContentControl 没有 c1 和 c2 属性。如果您创建一个自定义控件并将它们定义为依赖属性，它将起作用：

public class MyControl : ContentControl
{
    public string C1
    {
        get { return (string)GetValue(C1Property); }
        set { SetValue(C1Property, value); }
    }
    public static readonly DependencyProperty C1Property = DependencyProperty.Register(nameof(C1), typeof(string), typeof(MyControl));

    public string C2
    {
        get { return (string)GetValue(C2Property); }
        set { SetValue(C2Property, value); }
    }
    public static readonly DependencyProperty C2Property = DependencyProperty.Register(nameof(C2), typeof(string), typeof(MyControl));
}

XAML:

<ControlTemplate x:Key="FieldTemplate" TargetType="local:MyControl">
    <Border Background="LightGray" >
        <DockPanel >
            <TextBlock DockPanel.Dock="Left" Text="{TemplateBinding C1}" />
            <TextBlock DockPanel.Dock="Left" Text="{TemplateBinding C2}" />
            <TextBox />
        </DockPanel>
    </Border>
</ControlTemplate>
...
<local:MyControl C1="hello" C2="olleh" Template="{StaticResource FieldTemplate}" x:Name="NameControl"/>
