我有一个包含数据网格的 WPF 应用程序。数据网格绑定到我的对象 OrderBlock,该对象包含 Orders 类型的列表。
<DataGrid DataContext="{Binding OrderBlock}"
Name="dataGridOrdersGood"
ItemsSource="{Binding Orders}"
这工作正常,并在我的数据网格中很好地显示。我的列表中有一个属性(StatusGood),尽管我想将其显示为一个组合框,其中只能有两个值,“发送”或“保持”。
如果组合框中的值是“保持”,我希望该行变成不同的颜色。理想情况下使用从银色到黄色的线性渐变。我已经尝试了下面的代码 - 实际上只是暂时尝试将行变为红色,但没有任何反应。我看不到下面的代码有什么问题。触发部分非常接近下面代码的底部。我是 WPF 的新手,目前正在努力解决它。下面的代码主要来自一个很好的帖子,可以在这里找到,http://www.codeproject.com/Articles/586132/WPF-DataGrid-Custommization-using-Style-and-Templa
