with two DataTemplate
dependency properties: Template1
and Template2

中的Template1
。 How do I bind to this? 我该如何绑定? I tried using the following, but got binding exceptions:
我尝试使用以下内容,但遇到绑定异常:

<MyUserControl>
<MyUserControl.Template1>
<DataTemplate>
<StackPanel>
<TextBlock Text="This is in Template1!" />
<ContentControl ContentTemplate="???" />

</DataTemplate>
</MyUserControl.Template1>
