Question

我有两个对象练习和目标，每个练习都有一个目标。在后面的代码中，我设置了Exercises DataGrid的ItemsSource

 dgExercicios.ItemsSource = Repositorio<Exercicio>.GetAll();

在我的XAML中。

    <DataGrid Name="dgExercicios" CellStyle="{StaticResource CellStyle}" CanUserSortColumns="True" CanUserResizeColumns="True" AutoGenerateColumns="False">
         <DataGrid.Columns>
             <!--This bind works (Exercice.Nome)-->
             <DataGridTextColumn Header="Nome" Binding="{Binding Nome}" Width="200"   />
             <!--This bind DONT works (I Trying to bind to Exercise.Objective.Descricao)-->                     
             <DataGridTemplateColumn Header="Objetivo"  Width="80" >
                     <DataGridTemplateColumn.CellTemplate>
                         <DataTemplate  >
                             <StackPanel>
                                 <TextBlock Text="{Binding Path=Objective.Descricao}" T />
                              </StackPanel>
                          </DataTemplate>
                     </DataGridTemplateColumn.CellTemplate>
                 </DataGridTemplateColumn>
          </DataGrid.Columns>
      </DataGrid>

我想要做的是将属性Exercise.Objective.Descricao绑定到Exercice.Nome上的TextBlock

另一个问题，在这种情况下是否需要DataGridTemplateColumn？

Answer 1

如果Exercise类有一个名为Objective的属性，并且Objective类有一个名为Descricao的属性，那么它将起作用。

public class Exercicio
{
    public string Nome { get; set; }
    public Objective Objective { get; set; }

    public Exercicio(string nome, Objective objective)
    {
        this.Nome = nome;
        this.Objective = objective;
    }
}

public class Objective
{
    public string Descricao { get; set; }

    public Objective(string d)
    {
        this.Descricao = d;
    }
}

public MainWindow()
{
    InitializeComponent();

    var items = new ObservableCollection<Exercicio>(new[] {
        new Exercicio("Exercicio1", new Objective("Objective1")),
        new Exercicio("Exercicio2", new Objective("Objective2")),
        new Exercicio("Exercicio3", new Objective("Objective3"))
    });

    dgExercicios.ItemsSource = items;
}

如果您只想显示字符串，则不需要DataGridTemplateColumn：

<!-- Works now (also in a normal text column) -->
<DataGridTextColumn Binding="{Binding Path=Objective.Descricao}" Header="Objetivo" Width="80" />
