如何将ListBox从UserControl传递到ManWindow [英] How Do I Pass ListBox from UserControl to ManWindow

问题描述

我是WPF的新手，我需要一些关于将我的列表框从Usercontrol传递到MainWindow的帮助。



ListBox中的单词已经存储在数据库中，我只需要将ListBox传递给MainWindow。



这是我的UserControl.XAML。

Hi,

I am new to WPF and I need some help regarding passing my listbox from Usercontrol to MainWindow.

The words in the ListBox has been stored inside the database and I just need to pass the ListBox to the MainWindow.

This is my of UserControl.XAML.

<UserControl x:Name="Cloud1"
             x:Class="WpfCloud.UserControl1"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300">
    <Grid>
        <ListBox Height="100" HorizontalAlignment="Left" Margin="73,80,0,0" Name="listBox1" VerticalAlignment="Top" Width="120" />
    </Grid>
</UserControl>

这是我的UserControl.CS。

This is my UserControl.CS.

namespace WpfCloud
{
    /// <summary>
    /// Interaction logic for Cloudl1.xaml
    /// </summary>
    public partial class UserControl1 : UserControl
    {
        ServiceSoapClient _service;

        public UserControl1()
        {
            InitializeComponent();
            _service = new iDigitalService.ServiceSoapClient();
        }

        //public string UserControlTextBlockTemplate

        //{
        //    get { return TextBlockTemplate.Text; }
        //    set { TextBlockTemplate.Text = value; }

        //}

        private void UserControl1_Loaded(object sender, RoutedEventArgs e)
        {
            WordCloud cloud = _service.getLatestWordCloud();
            PlayWord[] words = cloud.words;

            foreach (PlayWord word in words)
            {
                string text = "(";
                text += word.wordID.ToString();
                text += ")    ";
                text += word.word;
                text += " : ";
                text += word.count.ToString();

                listBox1.Items.Add(text);
            }
        }
    }
}

这是我的MainWindow.XAML < br $>

This is my MainWindow.XAML

<Page x:Class="WpfCloud.Page1"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:local="clr-namespace:WpfCloud;assembly=WpfCloud"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
      mc:Ignorable="d" 
      WindowTitle="WordPlay" 
      Title="Page1" 
      Loaded="OnLoad" 
      d:DesignHeight="600" d:DesignWidth="800">
</Page>

是我的MainWindow.CS

This is my MainWindow.CS

namespace WpfCloud
{
    /// <summary>
    /// Interaction logic for Page1.xaml
    /// </summary>
    /// 

    public partial class Page1 : Page
    {
        List<TextBlock> _list;  //control for list it is a class command

        public Page1()
        {
            InitializeComponent();
        }
    }

推荐答案

这是关于将一​​个Argument传递给一个类的全部内容。使用ListBox作为Argument为MainWindow类创建额外的contstructor。



UserControl

it's all about passing an Argument to a class. make use of creating additional contstructor for the MainWindow class with ListBox as Argument.

UserControl

/// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class UserControl1 : UserControl
    {
        public Window1()
        {
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(Window1_Loaded);
        }

        private void Window1_Loaded(object sender, RoutedEventArgs e)
        {
            MainWindow mainWindow = new MainWindow(listBox1);
            mainWindow.ShowDialog();
        }
    }

在MainWindow

In MainWindow

/// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        ListBox _listBox = null;
        public MainWindow()
        {
            InitializeComponent();
        }
        public MainWindow(ListBox listBox)
        {
            InitializeComponent();
            _listBox = listBox;

        }
    }
