如何为选中的数据网格行设置透明背景？

Question

如果我使用像红色这样的普通颜色，就可以了。但是如果我使用透明，它在未聚焦时显示为白色，聚焦时显示为蓝色。我必须为 window 启用特殊设置吗？

这里是最低代码：

using System.ComponentModel;
using System.Linq;

using System.Threading.Tasks;

namespace test
{
    public partial class MainWindow : Window
    {
        public event PropertyChangedEventHandler PropertyChanged;
        protected void SetField<T> ( ref T field, T value, string propertyName )
        {
            if ( !EqualityComparer<T>.Default.Equals ( field, value ) )
            {
                field = value;
                PropertyChanged?.Invoke ( this, new PropertyChangedEventArgs ( propertyName ) );
            }
        }

        ObservableCollection<Coin> _coins;
        public ObservableCollection<Coin> Coins { get => _coins; set => SetField ( ref _coins, value, nameof ( _coins ) ); }
        public ICollectionView CollectionView;

        public MainWindow ( )
        {
            this.Coins = new ObservableCollection<Coin> ( );
            this.Coins.Add ( new Coin ( "Coin 1", 1 ) );
            this.Coins.Add ( new Coin ( "Coin 2", 2 ) );
            this.Coins.Add ( new Coin ( "Coin 3", 3 ) );
            this.Coins.Add ( new Coin ( "Coin 4", 4 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 5 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 6 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 7 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 8 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 9 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 10 ) );
            this.Coins.Add ( new Coin ( "Coin 5", 11 ) );

            this.DataContext = this;

            InitializeComponent ( );
        }
    }

    public class Coin
    {
        public string Symbol { get; set; }
        public int PNL { get; set; }
        public SolidColorBrush Color2 { get; set; }

        public Coin ( string symbol, int pnl )
        {
            this.Symbol = symbol;
            this.PNL = pnl;

            Random rnd = new Random ( );
            Color c = Color.FromRgb ( ( byte ) rnd.Next ( 256 ), ( byte ) rnd.Next ( 256 ), ( byte ) rnd.Next ( 256 ) );

            this.Color2 = new SolidColorBrush ( c );
        }
    }
}

Answer 1

你创造了一切 - DataGridRow.Background、DataGridCell.Background - 透明

选择后您可以看到白色的 DataGrid 背景 (#FFF) - 通过行和单元格

要解决此问题，请删除 IsSelected 触发器中背景的 setter：

<Trigger Property="IsSelected" Value="True">
    <Setter Property="BorderBrush" Value="#1e90ff" />
    <Setter Property="BorderThickness" Value="1" />
    <!--<Setter Property="Background" Value="Transparent"/>-->
</Trigger>

它将确保之前的触发器之一有效：

<Trigger Property="AlternationIndex" Value="0">
    <Setter Property="Background" Value="#141414"/>
</Trigger>
<Trigger Property="AlternationIndex" Value="1">
    <Setter Property="Background" Value="#282828"/>
</Trigger>

Answer 2

如果您正在寻找这样的东西：

我通过向 DataGridCell 的属性添加透明背景并从 IsSelected 触发器上的 DataGridRow 中删除黄色背景来做到这一点

更新

问题更新后，我刚刚删除了

<Setter Property="Background" Value="Transparent"/> 来自

<Style x:Key="RowStyleWithAlternation" TargetType="DataGridRow"> 在问题本身粘贴的原始代码中，这就是网格对我的看法

这是您要找的东西还是我遗漏了什么？
