Question

我在一份申请书中向用户展示了某一字的含义。因此,我在前面使用一个名单Box。这里是法典。

XAML:

<ListBox Background="White" Grid.Row="1" ItemsSource="{Binding}" Height="605" HorizontalAlignment="Stretch" Margin="0,90,0,0" Name="listBox1" VerticalAlignment="Top">
  <ListBox.ItemTemplate>
    <DataTemplate>
      <StackPanel Orientation="Vertical" Height="50">
        <TextBlock Text="{Binding ActualWord}" Height="5" />
        <TextBlock Text="{Binding Meaning}"  Height="5"/>
        <TextBlock Text="{Binding Type}" Height="5"/>
        <TextBlock Text="{Binding Example}" Height="5" />
      </StackPanel>
    </DataTemplate>
  </ListBox.ItemTemplate>
</ListBox>

C# 添加背后的措辞。

listBox1.Items.Add(new WordClass()
{
    ActualWord = "Something",
    Type = "Something111",
    Meaning =  "Something222",
    Example =  "Something333"
});

问题是,该守则汇编了,但我看着一个空白的屏幕,或换言之,在名单箱中没有任何东西,即使我是在页台上这样做的。

删除<代码>ItemsSource=”{Bled}> part from You XAML. 由于你手工填写清单,你不需要填写清单,这可能造成问题。

另一种选择是将你的XAML留给它,以填写<代码>WordClass,并将其定为<代码>DataContext:

var list = new List<WordClass>();
list.Add(new WordClass()
{
    ActualWord = "Something",
    Type = "Something111",
    Meaning =  "Something222",
    Example =  "Something333"
});
...

this.DataContext = list;
