I never really like using the visual tree helper for some reason but in cases like this it can be used.
出于某种原因，我从不喜欢使用可视化树助手，但在这种情况下可以使用它。
Basically what it does is hit test the control under the mouse as the right button is clicked and use the visual tree helper class to navigate up the visual tree until you hit a cell object.
基本上它的作用是在单击右键时对鼠标下的控件进行命中测试，并使用可视化树帮助器类向上导航可视化树，直到您击中一个单元格对象。
private void DataGrid_MouseRightButtonUp_1(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
var hit = VisualTreeHelper.HitTest((Visual)sender, e.GetPosition((IInputElement)sender));
DependencyObject cell = VisualTreeHelper.GetParent(hit.VisualHit);
while (cell != null && !(cell is System.Windows.Controls.DataGridCell)) cell = VisualTreeHelper.GetParent(cell);
System.Windows.Controls.DataGridCell targetCell = cell as System.Windows.Controls.DataGridCell;
// At this point targetCell should be the cell that was clicked or null if something went wrong.
}
