WPF——ListBox创建并连接后台数据
对如何通过WPF来创建一个listBox，并同后台数据链接，做一个简单的样例介绍。
首先现在XAML中创建一个ListBox并给个名字，以便在CS中引用到他。
<Window x:Class="listBox.MainWindow" 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:listBox" mc:Ignorable="d" Title="MainWindow" Height="450" Width="800"> <Grid> <ListBox Name="listBoxEmployee" Margin=" 5"/> </Grid></Window>
在CS中先定义一个employee类，并创建一个包含多个employee对象的list。再把list赋予给listBox且对要显示的对象属性进行一个声明。
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;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 listBox{/// <summary> /// MainWindow.xaml 的交互逻辑 /// </summary> public partial class MainWindow : Window {public MainWindow() {InitializeComponent(); //this.listBoxEmployee.SelectedValuePath = "id"; //把list和listBox做一个连接 this.listBoxEmployee.ItemsSource = emplist; //DisplayMemberPath告诉listBox应该显示list中每个对象的哪个属性 this.listBoxEmployee.DisplayMemberPath = "name"; } //创建一个employee对象的list List<Employee> emplist = new List<Employee>() {new Employee(){id = 11,name = "aaaa",age = 21 }, new Employee(){id = 2,name = "bbb",age = 22 }, new Employee(){id = 3,name = "ccc",age = 23 }, new Employee(){id = 4,name = "ddd",age = 24 }, new Employee(){id = 5,name = "eeee",age = 25 }, new Employee(){id = 6,name = "ffff",age = 26 }, new Employee(){id = 7,name = "gggg",age = 27 }, new Employee(){id = 8,name = "hhh",age = 28 }, new Employee(){id = 9,name = "iii",age = 29 }, new Employee(){id = 10,name = "jjjj",age = 30 } }; //创建一个Employee的类 public class Employee {public int id { get; set; } public string name { get; set; } public int age { get; set; } }
注：当代码复杂时，可以把类的定义以及list的生成换到别的位置，来优化下代码的可读性。
