Question

下面是我的对象作为XML的示例。由于隐私，我不得不取出实际数据，但你应该得到一些事情的要点。目前我的绑定工作相当不错，但是我无法获得一个填充必要的Granchild信息的方框。列表框工作正常，它可能是我最终没有看到的逻辑问题。

每个医生都可以有一个或多个医生办公室，但每个医生办公室只属于一个集合，这个集合本身就是一个集合。 Nettiers启用IdSource属性，允许您定义孙元素而不是遍历层次结构。这就是我要填写的内容.GroupIdSource正在填充，但绑定根本没有抓住它。

<TextBlock Grid.Row="0" Grid.Column="1" Background="blue" FontSize="12" 
           FontWeight="Bold" >
  **<Label Content="{Binding Path=GroupIdSource.GroupName}**"/>

这是我的全XAML也可以提供帮助。我有一个。上面的数据绑定工作，但它绑定到我的数据视图的方式有所不同。它直接绑定到对象然后它的子...你可以在NPINumber的第一个列表框中看到它......

Answer 1

绑定XML数据源时，应使用XPath代替Path来获取所需的元素/属性。

编辑：您需要以某种方式将对象设置为控件（或其祖先之一）的datacontext，然后您可以引用它的任何属性或嵌套属性。例如，在您的情况下：

...{Binding Path=DoctorOfficesCollection[0].GroupIdSource.GroupName}...

我终于在阅读之后表现得很好。但实际上在语法上我的代码没有任何变化，除非我遗漏了关于wpf控件如何工作的内容。我可能会慢慢解除这些变化，因为无论如何它都在测试视图中，看看我是否可以复制问题。以下是可能遇到类似问题且需要知道如何执行此操作的任何人的工作代码。

                                    <TextBlock Text="{Binding Path=AlternatePhone1, StringFormat='Alternate Phone 1: {0}'}" 
                                       Visibility="{Binding Path=AlternatePhone1, Converter={StaticResource TextToVisibilityConverter}}" />
                                    <TextBlock Text="{Binding Path=AlternatePhone2, StringFormat='Alternate Phone 2: {0}'}"
                                        Visibility="{Binding Path=AlternatePhone2, Converter={StaticResource TextToVisibilityConverter}}" />
                                </StackPanel>
                            </StackPanel>

正如你所看到的，我所做的唯一不同的事情就是将一个组框设置为列表框的原始数据绑定，然后将itemsource更改为{bindings}。其他任何改变都不应该产生任何实际效果。

如何对子对象的子对象进行数据绑定？
