下拉框不是用来单选的么？多行就没意义了吧？！

下面是我以前写的一个界面, 里面就有应用到DataTemplate.
关于DataTemplate, 你可以百度一下.
除了DataTemplate, 你还可以用ControlTemplate, 不过DataTemplate更轻量.

}
List<ST> ListSource = new List<ST>()
{
new ST(){ Id =101,Name="S1",Grade="G2"},
new ST(){ Id =102,Name="S2",Grade="G1"},
new ST(){ Id =103,Name="S3",Grade="G4"},
new ST(){ Id =104,Name="S4",Grade="G3"},
};
public Window2()
{
InitializeComponent();
List<ST> list = new List<ST>();
this.dataGrid1.ItemsSource = list;
this.h1.ItemsSource = ListSource;
}
}
}

如果我用DataTemplate感觉很难把选择的数据填入表格中

选择后第一列：填Id,第二列填：Name第三列填Grade
