Ag UserControl 是否可以公开供 XAML 绑定的属性？

我有一个由 UserControl01.cs 支持的新 UserControl，它公开了两个属性。一种是普通的旧 CLR 属性，另一种是较新的 DP 属性格式。例如：

string PropertyOne {get;set;}

第二个属性是公共 DP（构造太长，无法在此处列出）。

从 XAML 方面，我希望公开这些值。我怎样才能做到这一点？

在这两个属性（旧的 CLR 以及第二个 DP 包装器格式）上，我尝试过如下语法：

 <TextBlock Text={Binding Prop1}/>
 <TextBlock Text={Binding Source=., Path=Prop1}/>

我尝试在资源字典中放置对类类型的引用并引用它，

 <TextBlock Text={Binding Source={StaticReference myType}, Path=Prop1}/>

但这显然最终会导致堆栈溢出，如下所示该字典实例化该控件的第二个副本。

我在某处读到一篇文章，在 WPF 中可以 x:Name 控件本身，但是

  <TextBlock Text="{Binding {ElementName=theName, Path=Prop1}"/>

我们在 Ag 中没有 ElementName 绑定，所以这不是方法。

如何绑定到 UserControl 的属性？任何财产！
如果这是不可能的，并且您只能绑定到 DTO 或其他 BO，那么我们应该如何设计想要公开其值的 UserControls 的指导逻辑/解释是什么？

原文

I have a new UserControl backed by UserControl01.cs that is exposing two properties. One is a plain old CLR property, the other the newer DP property format.
eg:

string PropertyOne {get;set;}

and the second property is a public DP (construct is too long to list here).

From the XAML side, I wish to expose these value. How can I do that?

On both properties (old CLR as well as second DP wrapper format) I've tried syntax like:

 <TextBlock Text={Binding Prop1}/>
 <TextBlock Text={Binding Source=., Path=Prop1}/>

I've tried putting a ref to the class type in the Resource dictionary and referencing it with

 <TextBlock Text={Binding Source={StaticReference myType}, Path=Prop1}/>

but that obviously ends up being a stack overflow as the dictionary instantiates a second copy of the Control.

I read a post somewhere that in WPF one can x:Name the control itself, and then

  <TextBlock Text="{Binding {ElementName=theName, Path=Prop1}"/>

but we don't have ElementName binding in Ag, so that's not the way.

How can I bind to the UserControl's property? Any property!
If that's not possible, and you can only bind to DTO's or other BO's, what's the guiding logic/explanation as to how we should design UserControls that want to expose their values?
