DataGrid使用右键选中当前行

今天有朋友问到DataGrid控件右键选中当前行的问题，对该方法做一个记录。

  void dg_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.MouseRightButtonDown += (s, a) =>
            {
                a.Handled = true;
                (sender as DataGrid).SelectedIndex = (s as DataGridRow).GetIndex();
                (s as DataGridRow).Focus();
            };
        }
