wpf绑定用户控件及listview（gridview）数据源

用户控件：

前台界面

<UserControl x:Class="testUserControl.project" 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> <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>

后台代码

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; using System.Collections.ObjectModel; namespace testUserControl { /// <summary> /// Interaction logic for project.xaml /// </summary> public partial class project : UserControl { #region Member private ObservableCollection<ModelClass> ModelClassList = new ObservableCollection<ModelClass>(); #endregion #region Properties /// <summary> /// 用于保存数据实体的集合 /// ObservableCollection这个集合可以实时和前台交互，也就是说 /// 只需要修改集合中的内容，前台的ListView会自动刷新，不需要手动刷新 /// </summary> public ObservableCollection<ModelClass> _ModelClassList { get { return ModelClassList; } set { ModelClassList = value; } } #endregion #region Constructor public project() { InitializeComponent(); //指定数据源来自哪个对象（我理解是这样的） lvData.DataContext = this; for (int i = 0; i < 100; i++) { ModelClass m = new ModelClass() // 我在这里给ModelClass赋值，不管你数据库里是Data还是pname ，到这里，都给Data，前台不需要动 { ID = i, Data = "test" }; _ModelClassList.Add(m); } //讲集合赋给listview lvData.ItemsSource = _ModelClassList; //照这个写，只要修改ModelClass类里的内容，然后添加到集合里就可以了 //DataGrid控件实际也是这样的 } #endregion #region Event private void button1_Click(object sender, RoutedEventArgs e) { ModelClass m = lvData.SelectedItem as ModelClass; _ModelClassList.Remove(m); } #endregion } }

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); } } }
