C#WPF在CellEditEnding事件后更改数据网格单元格背景

我的C#wpf应用程序中有一个Datagrid(DataGridMeterValues(。每当用户退出单元格的编辑模式时，都会触发CellEditEnding事件。

现在，我希望在触发事件时更改单元格的背景。

这就是我目前所得到的：

private void DataGridMeterValues_CellEditEnding(object sender, System.Windows.Controls.DataGridCellEditEndingEventArgs e)
{
// Code to change background color here
}

我可以用以下代码更改整行的背景：

e.Row.Background = Brushes.Yellow;

现在我的问题是，我可以做同样的事情，但只针对1个单元格(选定的一个(，而不是整个行

编辑：这是数据网格的XAML
