[英]How to bind a template element property in DataTemplate
I want to let a template element property create a binding with another element property, but I found a lot articles and none of them talk about. 我想让模板元素属性创建与另一个元素属性的绑定,但是我发现了很多文章,但都没有谈论。 So I ask for what should I do. 所以我问我该怎么办。

You can directly bind CompplexProperty.PartA and PartB also you can use ElementName method, In the below code you can see the both ways also. 您可以直接绑定CompplexProperty.PartA和PartB,也可以使用ElementName方法,在下面的代码中,您也可以看到两种方式。

<TextBlock.Text>
<MultiBinding Converter="{StaticResource join_converter}">
<Binding ElementName="ATextblock" Path="Text">
</Binding>
<Binding Path="ComplexProperty.PartB">
</Binding>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
