用户控件：

前台界面

        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="22,0,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
        <ListView Name="lvData" Width="200" Height="200" Margin="12,29,88,71">
            <ListView.View>
                <GridView>
                    <GridViewColumn Width="100" Header="ID" DisplayMemberBinding="{Binding ID}"/>
                    <GridViewColumn Width="100" Header="Data" DisplayMemberBinding="{Binding Data}"/>
                </GridView>
            </ListView.View>
        </ListView>
    </Grid>
</UserControl>

实体类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace testUserControl
{
    public class ModelClass
    {
        public int ID { get; set; }
        public string Data { get; set; }//这个data对应不是数据库中的data字段啊？这个还不是随便你的么，规范的话，要一样，不一样么，反正程序是不会出错啦。
    }
}

 

方法一：

后台绑定用户控件

前台：

<Window x:Class="testUserControl.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
    
    <Grid Name="Layout">
       
    </Grid>
</Window>

后台：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace testUserControl
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            project project = new project();
            Layout.Children.Add(project);
        }
    }
}
