WPF dataGrid初步使用案例

xaml 1 界面设计  

 

<Window x:Class="Wpf.Template.One.Demo.NumberOne.dataGrid"
        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:Wpf.Template.One.Demo.NumberOne"
        mc:Ignorable="d"
        Title="dataGrid" Height="450" Width="800" Loaded="Window_Loaded">
    <Grid>
        
        <DataGrid FontSize="20" Name="grid1" ItemsSource="{Binding}" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridTextColumn Header="用户姓名" Binding="{Binding Name}">DataGridTextColumn>
                <DataGridTextColumn Header="年龄" Binding="{Binding Age}">DataGridTextColumn>
                
                <DataGridComboBoxColumn x:Name="depts" Header="部门" SelectedValueBinding="{Binding DeptId}">DataGridComboBoxColumn>
            DataGrid.Columns>
 
            
            
            
            
        DataGrid>
    Grid>
Window>

 2 逻辑代码

  

using System;
using System.Collections.Generic;
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.Shapes;
 
using Wpf.Template.One.Entity;
 
namespace Wpf.Template.One.Demo.NumberOne
{
    /// 
    /// dataGrid.xaml 的交互逻辑
    /// 
    public partial class dataGrid : Window
    {
        public dataGrid()
        {
            InitializeComponent();
        }
 
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            // 集合创建 
            List list = new List();
            list.Add( new userInfo() { Name="张三",Age=22,deptId=1001});
            list.Add(new userInfo() { Name = "李斯", Age = 32, deptId = 1002 });
            list.Add(new userInfo() { Name = "王武", Age = 42, deptId = 1003 });
 
 
            //集合 2 
            List deplist = new List();
            deplist.Add(new depInfo() { Id = "1001", DeptName = "研发技术部" });
            deplist.Add(new depInfo() { Id = "1002", DeptName = "销售部" });
            deplist.Add(new depInfo() { Id = "1003", DeptName = "人事部" });
 
            this.depts.ItemsSource = deplist;
            //展示项 用部门名称
            this.depts.DisplayMemberPath = "DeptName";
            this.depts.SelectedValuePath = "Id";
 
            //直接赋值 list 
            this.grid1.DataContext = list;
 
 
 
        }
    }
}

 还有2个实体类

  1 用户实体类

  

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

namespace Wpf.Template.One.Entity
{
     class userInfo
    {
        public string  Name { get; set; }
        public int Age { get; set; }
        public int deptId { get; set; }
    }
}
 

2 部门实体类

 

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

namespace Wpf.Template.One.Entity
{
      class depInfo
    {
        //prop 快捷输入 
        public string Id { get; set; }

        ///

        /// 部门名称
        ///

        public string  DeptName { get; set; }
    }
}
