列表框不显示项目c# xaml
本文关键字:xaml 项目 显示 列表 | 更新日期: 2023-09-27 18:03:39
我已经在xaml:
中写了这个 <ListBox x:Name="WorkersList">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding name}"></TextBlock>
<TextBlock Text="{Binding gehalt}"></TextBlock>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
然后我写了一个名为"worker"的c#类,并将以下代码添加到mainpage.cs中:
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
List<Worker> sourceworkerlist = new List<Worker>();
sourceworkerlist.Add(new Worker { name = "Franz", gehalt = 200 });
WorkersList.DataContext = sourceworkerlist;
}
}
我运行程序,但结果是我没有看到listboxitem:(我做错了什么?谢谢你的回答!
如果你想在你的代码后面使用DataContext
,那么你的XAML应该是这样的:
<ListBox x:Name="WorkersList" d:DataContext="{d:DesignInstance {x:Type local:Worker}}" ItemsSource="{Binding Mode=OneWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding name}"/>
<TextBlock Text="{Binding gehalt}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
完整的XAML文件:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication11" mc:Ignorable="d"
x:Class="WpfApplication11.MainWindow"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ListBox x:Name="WorkersList" d:DataContext="{d:DesignInstance {x:Type local:Worker}}" ItemsSource="{Binding Mode=OneWay}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding name}"/>
<TextBlock Text="{Binding gehalt}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Window>
您需要将ItemsSource绑定到DataSource,或者在代码中设置ItemsSource。
WorkersList.ItemsSource = sourceworkerlist;
或
<ListBox x:Name="WorkersList" ItemsSource="{Binding}">
