Xaml：

cs代码：

private void datagrid_MouseDoubleClick(object sender, MouseButtonEventArgs e){　　DataGrid datagrid = sender as DataGrid;　　Point aP = e.GetPosition(datagrid);　　IInputElement obj = datagrid.InputHitTest(aP);　　DependencyObject target = obj as DependencyObject;

　　while (target != null)　　{　　　　if (target is DataGridRow)　　　　{　　　　　　break;　　　　}　　　　target = VisualTreeHelper.GetParent(target);　　}}

// 获取点击行的数据

DataGrid datagrid = sender as DataGrid; Bom row = datagrid.SelectedItem as Bom;

WPF DataGrid使用简介 1）自动生成列 2）取消自动生成列，手动绑定到相应字段最后一列设置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); } }
