1）自动生成列"True" Name="datagrid" CanUserAddRows="False" MouseDoubleClick="datagrid_MouseDoubleClick" />2）取消自动生成列，手动绑定到相应字段"False" Name="datagrid" CanUserAddRows="False" MouseDoubleClick="datagrid_MouseDoubleClick">"编号" Binding="{Binding ID}">"公司" Binding="{Binding CompanyName}">"固定资产" Binding="{Binding FixedAssets}" Width ="*">最后一列设置Width ="*"是为了取消空白列。（3）后台代码private void Window_Loaded(object sender, RoutedEventArgs e){datagrid.ItemsSource =
AccessDAL.OleDbHelper.ExecuteDataTable("SELECT * from Customers").DefaultView;}//双击DataGrid，显示相应信息private void datagrid_MouseDoubleClick(object sender, MouseButtonEventArgs
e){DataRowView row = datagrid.SelectedItem
as DataRowView;MessageBox.Show(row["id"].ToString());}//如果绑定到对象集合，如ObservableCollection，代码如下：ObservableCollection col;public EmployeeManage(){InitializeComponent();col = new ObservableCollection();col.Add(new Employee() { Id = 1, Name =
"Jim", Salary = 2500.50f });col.Add(new Employee() { Id = 2, Name =
"John", Salary = 2600.50f });datagrid.ItemsSource = col;}private void datagrid_MouseDoubleClick(object sender, MouseButtonEventArgs
e){Employee emp=datagrid.SelectedItem
as Employee;MessageBox.Show(emp.Id.ToString());}（4）删除选中的多行数据private void Delete_Click(object sender, RoutedEventArgs e){for (int i = datagrid.SelectedItems.Count - 1; i >=
0; i--){Good good = datagrid.SelectedItems[i]
as Good;goods.Remove(good);}}
