[英]Binding nested JSON to listbox in XAML
這是我的情態
public class main
{
public List<categories> categorieslist { get; set; }
}
public class categories
{
public int categoryId { get; set; }
public string categoryName { get; set; }
public List<pdf> pdfdocs { get; set; }
public List<video> videoFiles { get; set; }
}
public class pdf
{
public string URL { get; set; }
public string language { get; set; }
public string createdDate { get; set; }
public bool isFavorite { get; set; }
public bool isRead { get; set; }
}
我正在使用JSON.NET反序列化
main mainobj = JsonConvert.DeserializeObject<main>(App.hello);
我需要顯示選定類別的PDF列表,我使用LINQ來過濾特定類別,我無法綁定PDF列表。
pdf.ItemsSource = App.mainobj.categorieslist.Where(i => i.categoryId.Equals(s));
<ListBox x:Name="pdf" Margin="0,0,0,363" ItemsSource="{Binding}" Foreground="White">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding pdf.URL}" Foreground="White"></TextBlock>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListBox ItemsSource="{Binding categorieslist}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding categoryId }" FontSize="20" />
<ItemsControl ItemsSource="{Binding pdf}" Margin="0 20 0 0">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Blue" BorderThickness="2">
<TextBlock Text="{Binding URL }" FontSize="20" />
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
<ItemsControl ItemsSource="{Binding videoFiles}" Margin="0 20 0 0">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Red" BorderThickness="2">
<TextBlock Text="{Binding URL}" FontSize="20" />
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
