Question

如何让我的类属性显示在ListBox中？

XAML：

<ListBox x:Name="lstPlayers" >
     <DataTemplate>
          <StackPanel Orientation="Horizontal">
              <TextBlock Text="{Binding Player.FirstName}"></TextBlock>
              <TextBlock Text="{Binding Player.LastName}"></TextBlock>
          </StackPanel>
     </DataTemplate>
</ListBox>

C＃：

public class Player
{
    string FirstName { get; set; }
    string LastName { get; set; }
}


public void LoadPlayers()
{
    foreach (Player player in Players)
    {
         lstPlayers.Items.Add(player);
     }
}

ListBox中唯一显示的是

TestApplication1.Player

Answer 1

您当前的实施遇到了一些问题。首先，DataTemplate应该放在ListBox的ItemTemplate中。其次，每个ListBoxItem的DataContext都是Player的实例，因此您应该直接绑定到FirstName和LastName。第三，Player中的属性应该公开，以使DataBinding起作用。

<ListBox x:Name="lstPlayers" >
    <ListBox.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding FirstName}"></TextBlock>
                <TextBlock Text="{Binding LastName}"></TextBlock>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

public class Player
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

此外，不要将项目逐项添加到ListBox，而只需将其设置为ItemsSource

lstPlayers.ItemsSource = Players;

Answer 2

DataTemplate应该在ListBox.ItemTemplate中。

Answer 3

设置集合，Players as ItemSsource

和

<ListBox x:Name="lstPlayers" >
        <ListBox.ItemTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal">
                    <TextBlock Text="{Binding FirstName}"></TextBlock>
                    <TextBlock Text="{Binding LastName}"></TextBlock>
                </StackPanel>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

Answer 4

您必须将DataType添加到DataTemplate。

<DataTemplate DataType="{x:Type local:Player}">
        <StackPanel Orientation="Horizontal">
            <TextBlock Text="{Binding FirstName}"></TextBlock>
            <TextBlock Text="{Binding LastName}"></TextBlock>
        </StackPanel>
    </DataTemplate>

local是TestApplication1.Player的命名空间。您可以将datatemplate设置为listebox.itemtemplate或任何“父对象”的资源

XAML ListBox仅显示类名
