C# 如何基于项目属性设置按钮背景-WPF

我在动态创建单选按钮，这意味着我在数据库项目中循环，并显示样式单选按钮，下面是我的代码：

public ObservableCollection<Product> products = new ObservableCollection<Product>(ProductsController.SelectAllProducts());

if (products.Count > 0)
{
    foreach(var item in products)
    {
        SolidColorBrush mySolidColorBrush = new SolidColorBrush();
        mySolidColorBrush = (SolidColorBrush)(new BrushConverter().ConvertFrom("#004a80"));
        RadioButton a = new RadioButton();
        a.BorderThickness = new Thickness(1);
        a.Background = Brushes.Green;
        a.Foreground = new SolidColorBrush(Colors.Black);
        a.BorderBrush = mySolidColorBrush;
        a.Width = 118;
        a.Height = 70;
        a.Margin = new Thickness(5,0,0,5);
        Style style = Application.Current.Resources["MyRadioButtonAsButtonStyle"] as Style;
        a.Style = style;
        a.ApplyTemplate();
        a.Content = item.OrdinalNumber;
        Image imgControl = (Image)a.Template.FindName("img", a);
        Image imgControlWhite = (Image)a.Template.FindName("whiteImg", a);
        TextBlock text = (TextBlock)a.Template.FindName("text", a);

        if (fileNames.Count > 0)
        {
            if (!fileNames.Any(item.Description.Contains))
            {
                item.IsProcessed = true; // SETTING PROPERTY
            }
        }


        a.Click += (object sender, RoutedEventArgs e) =>
        {
            var radioButton = sender as RadioButton;
            MessageBox.Show(radioButton.Content.ToString());
        };
        text.Text = item.Title;
        imgControl.Source = image;
        spProducts.Children.Add(a);
    }
}

}

这是我的定制风格，我第一次将背景设置为绿色：

所以基本上我不知道如何检查

item.IsProcessed

在

app.xaml

中的值，所以我可能会根据该属性值为背景添加setter

任何形式的帮助都会很好

谢谢

在您的

样式中添加
数据触发器如何

<ControlTemplate.Triggers>
    <Trigger Property="IsChecked" Value="True">
        <Setter TargetName="gridProduct" Property="Background" Value="Orange"/>
        <Setter TargetName="tekst" Property="Foreground" Value="White"/>
    </Trigger>
    <DataTrigger Binding="{Binding IsProcessed}" Value="True">
        <Setter TargetName="gridProduct" Property="Background" Value="Green"/>
    </DataTrigger>
</ControlTemplate.Triggers>

通常，您将使用绑定到
可观察集合的
项控件
，并在
项模板
中定义
单选按钮
，您可以实现
IValueConverter
，它会将BoL转换为后台对象。你应该考虑使用ItEsScript控件，而不是在代码后面创建UI元素。@米莎·TurcZyn，我该怎么做？你能帮我举个例子吗，我从昨天开始就在努力解决这个问题：（@Clemens因为我的元素取决于我在数据库中有多少个项目，我认为这样创建可能会很好，你能提供你的例子吗？感谢“基于项目属性的背景”，这通常由绑定到item属性的DataTrigger完成。谁是老板？mm8是老板！非常感谢先生！
