WPF DataGrid禁用一行但允许一个单元格

private void DataGridCell_Click(object sender, RoutedEventArgs e)
{
    // 获取当前点击的单元格
    DataGridCell cell = sender as DataGridCell;

    // 获取单元格所在行和列的索引
    int rowIndex = DataGridRow.GetRowContainingElement(cell.Parent as FrameworkElement).GetIndex();
    int columnIndex = cell.Column.DisplayIndex;

    // 将整行设置为禁用状态
    DataGridRow row = dataGrid.ItemContainerGenerator.ContainerFromIndex(rowIndex) as DataGridRow;
    row.IsEnabled = false;

    // 将当前单元格设置为可编辑状态
    cell.IsEditing = true;
}
