DataGrid 中Combox的使用

前台代码：

<Window x:Class="WpfApp1.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:core="clr-namespace:System;assembly=mscorlib"
xmlns:local="clr-namespace:WpfApp1"
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}}" />
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>

后台代码：

namespace WpfApp1
{

public class Customer
{
public SexEnum sex { get; set; }
}
public enum SexEnum { 男,女 };


public partial class MainWindow : Window
{
ObservableCollection<Customer> custdata = new ObservableCollection<Customer>();

public MainWindow()
{
InitializeComponent();

Customer cm = new Customer();
cm.sex = SexEnum.男;
custdata.Add(cm);

DG1.DataContext = custdata;

}
}
}
