我有一个listview,想要使用某种控件动态地添加项目。例如 enter image description here

提供" pack1" " PACK2"是ListViewItems我希望有额外的(红色方块)控件,它始终可见并添加新的" pack"点击项目。 所以任务很标准。通常如何完成?

更新 CompositeCollection似乎是一个很好的解决方案。

我用listview做了一个非常简单的布局。我在listview项目中添加了一个按钮,并在按钮之前监听单击以插入新对象。

public MainWindow()
    {
        InitializeComponent();
        listViewtst.Items.Add("test");
        listViewtst.Items.Add("test2");
        Button btn = new Button();
        btn.Content = "+";
        btn.Click += Btn_Click;
        listViewtst.Items.Add(btn);
    }

    private void Btn_Click(object sender, RoutedEventArgs e)
    {
        listViewtst.Items.Insert(listViewtst.Items.Count - 1, "added by the btn");

    }

不确定这是否是最佳解决方案,但如果没有人向我展示更好的方法,我会这样做:)

其他解决方案:

背后的代码

    /// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    private ObservableCollection<MyObject> _windows = new ObservableCollection<MyObject>();

    public MainWindow()
    {
        InitializeComponent();
        Windows.Add(new MyObject { Title = "Collection Item 1" });
        Windows.Add(new MyObject { Title = "Collection Item 2" });
    }

    private void Btn_Click(object sender, RoutedEventArgs e)
    {


    }

    public ObservableCollection<MyObject> Windows
    {
        get { return _windows; }
        set { _windows = value; }
    }

    private void button_Click(object sender, RoutedEventArgs e)
    {
        Windows.Add(new MyObject { Title = "From Btn" });
    }
}

public class MyObject
{
    public string Title { get; set; }
}

Xaml:

<Window x:Class="Move_To_Prd_Dev.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="246" Width="325" Name="UI">
<Window.Resources>
    <CollectionViewSource Source="{Binding ElementName=UI, Path=Windows}" x:Key="YourMenuItems"/>
</Window.Resources>
<Grid DataContext="{Binding ElementName=UI}">
    <ListBox x:Name="listTxt" HorizontalAlignment="Left" Height="163" Margin="10,29,0,0" VerticalAlignment="Top" Width="297">
        <ListBox.ItemsSource>
            <CompositeCollection>
                <CollectionContainer Collection="{Binding Source={StaticResource YourMenuItems}}" />
                <Button x:Name="button" Content="Button" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Click="button_Click"/>

            </CompositeCollection>
        </ListBox.ItemsSource>
    </ListBox>

</Grid>

这使用CompositeCollection将按钮控件添加到列表中(优点是按钮始终为Last)
