WPF DataGrid中单元格运用Combobox的示例

 

效果图：

前端代码：

<Window x:Class="WPFDemo.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:WPFDemo"
         xmlns:core="clr-namespace:System;assembly=mscorlib"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Window.Resources>
        <ObjectDataProvider x:Key="SexEnumKey" MethodName="GetValues" ObjectType="{x:Type core:Enum}">
            <ObjectDataProvider.MethodParameters>               
                <x:Type Type="local:SexEnum"/>  
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
    </Window.Resources>
    <Grid>
        <DataGrid Name="DG1" ItemsSource="{Binding}" CanUserAddRows="False" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridComboBoxColumn Header="性别" SelectedItemBinding="{Binding Sex}" ItemsSource="{Binding Source={StaticResource  SexEnumKey}}"></DataGridComboBoxColumn>
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</Window>

后端代码：

using System.Collections.ObjectModel;
using System.Windows;

namespace WPFDemo
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        ObservableCollection<DTO> list = new ObservableCollection<DTO>();
        public MainWindow()
        {
            InitializeComponent();

            for (int i = 0; i < 5; i++)
            {
                list.Add(new DTO()
                {
                    Sex = i == 0 ? SexEnum.boy : SexEnum.girl
                });
            }
            DG1.DataContext = list;
        }
    }
    public enum SexEnum { boy, girl }
    public class DTO
    {
        public SexEnum Sex { get; set; }
    }
}
