xamdatagrid基于列表框中选定的项目绑定

Question

我正在尝试基于从列表框中的选定项目加载datagrid。

您能帮我如何实现。

下面是我的模型

艺术家班

public class Artist.
{
public string Name { get; set; }
public int Age { get; set; }
}

电影类

public class Movie
{
private string _Name = string.Empty;
public string Name
{
get
{
return _Name;
}
set
{
_Name = value;
}
}
private List _Artists = new List();
public List Artists
{
get
{
return _Artists;
}
set
{
_Artists = value;
}
}
}

ViewModel类

public class ViewModel
{
private List _Movies;
public List Movies
{
get
{
return _Movies;
}
set
{
_Movies = value;
}
}
public ViewModel()
{
_Movies = new List();
Movie movie = new Movie();
movie.Name = "Movie 1";
List artists = new List();
Artist artist1 = new Artist();
artist1.Name = "Artist 1";
artist1.Age = 27;
artists.Add(artist1);
movie.Artists = artists;
_Movies.Add(movie);
//2nd record
movie = new Movie();
movie.Name = "Movie 2";
artists = new List();
artist1 = new Artist();
artist1.Name = "Artist 2";
artist1.Age = 27;
artists.Add(artist1);
movie.Artists = artists;
_Movies.Add(movie);
}
}

下面是XAML- viewModel对象绑定到窗口datacontext

<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ListBox Name="MoviesList" Grid.Column="0" Width="150" ItemsSource="{Binding Movies}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<igWPF:XamDataGrid Grid.Column="1" DataSource="{Binding Movies}">
<igWPF:XamDataGrid.FieldLayouts>
<igWPF:FieldLayout>
<igWPF:Field Name="Name"/>
</igWPF:FieldLayout>
</igWPF:XamDataGrid.FieldLayouts>
</igWPF:XamDataGrid>
</Grid>

如果要在DataGrid中展示所选电影的艺术家，请尝试一下：

<igWPF:XamDataGrid Grid.Column="1" DataSource="{Binding SelectedItem.Artists, ElementName=MoviesList}">
