绑定到一些嵌入式对象属性 [英] Bind to some embedded object properties

问题描述

我有一个汽车的IEnumerable ：

public IEnumerable<ICars> Cars { get; private set; }

对象车，实际上包含了类型IBrand的另一个对象的引用：

The object "Car" actually contains a reference to another object of type IBrand:

public interface ICar
{
    // Parent brand accessor
    IBrand Brand { get; set; }

    // Properties
    int CarId { get; set; }
    string CarName { get; set; }
}

该IBrand接口有一些属性：

The IBrand interface has some properties:

public interface IBrand
{
    // Properties
    string LogoName { get; set; }
    string Sector { get; set; }
}

我绑定此车的IEnumerable到DataGrid - 此workds完美的罚款

<DataGrid Name="Cars"
          ItemsSource="{Binding}"
          SelectedItem="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}, AncestorLevel=2}, Path=SelectedCar, Mode=TwoWay}">
  <DataGrid.Columns>
    <DataGridTextColumn Header="Car Id"
                        Binding="{Binding CarId}"
                        IsReadOnly="True" />
    <DataGridTextColumn Header="Car Name"
                        Binding="{Binding CarName}"
                        IsReadOnly="True" />
  </DataGrid.Columns>

我的问题是，我想结合从品牌的一些特性以及（适用于所有的车），例如像标志。 此synthax不工作，虽然

My problem is that I'd like to bind some properties from the Brand as well (common to all the cars), like for example the logo. This synthax doesn't work though:

<DataGridTextColumn Header="Logo Name"
                    Binding="{Binding Brand.LogoName}"
                    IsReadOnly="True" />

这是如何做到这一点任何想法？谢谢！

Any idea on how to do so? Thank you!

推荐答案

当你使用，你需要指定路径虚线路径明确关键字。这应该工作：

When you use a dotted path you need to specify the Path keyword explicitly. This should work:

<DataGridTextColumn Header="Logo Name" Binding="{Binding Path=Brand.LogoName}" IsReadOnly="True" />
