如何获取DataGridTextColumn发送者的datagrid父级

private DataGrid FindParentDataGrid(DependencyObject child)
{
    DependencyObject parent = VisualTreeHelper.GetParent(child);

    while (parent != null && !(parent is DataGrid))
    {
        parent = VisualTreeHelper.GetParent(parent);
    }

    return parent as DataGrid;
}

private void DataGridCell_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
    DataGridCell cell = sender as DataGridCell;
    DataGrid dataGrid = FindParentDataGrid(cell);

    if (dataGrid != null)
    {
        // 在这里使用dataGrid进行操作
    }
}
