如何为选定的数据网格行设置透明背景？答案

【问题标题】：How to set transparent background for the selected data grid row?如何为选定的数据网格行设置透明背景？

【问题描述】：

如果我使用像红色这样的普通颜色，它会起作用。但是如果我使用透明，它在未聚焦时显示为白色，在聚焦时显示为蓝色。我必须为窗口启用特殊设置吗？

这是最少的代码：

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 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 );
        }
    }
}

【问题讨论】：

会不会是窗口背景造成的？您能否将窗口的背景设置为红色或透明，看看这是否会影响您看到的内容。
@XAMlMAX 这个我刚试过，还是一样，不知道怎么回事。
所以你的主要问题是什么时候没有被选中或者什么时候被选中？不管怎样，这看起来像是DataGridRow 风格的问题。我建议在 Blend 中编辑并覆盖模板。这可能与 Button 的问题相同。那里有一个不打球的边界。试一试，看看会发生什么。
@XAMlMAX 被选中时。当它没有被选中时，它看起来是正确的。当窗口不在焦点时，它也会改变选择颜色，所以我也必须改变它。我不想让焦点改变选择颜色。
我明白了，我会看看并尝试重现这个（现在是上午 10 点我所在的位置），今天下午。我认为一旦你覆盖了模板，它就会修复它。

【解决方案1】：

如果你正在寻找这样的东西：

我通过在 DataGridCell 的属性中添加透明背景并在 IsSelected 触发器上从 DataGridRow 中删除黄色背景来做到这一点

更新

问题中更新后，我刚刚删除了

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

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

这是你要找的还是我错过了什么？

【讨论】：

谢谢我刚刚尝试了交替行颜色，它似乎不起作用。你能试一试吗？我更新了 OP。
嘿，我尝试使用新代码并更新了我的答案。您能否看一下屏幕截图，如果您希望网格看起来像这样，请告诉我？
非常感谢，当我复制粘贴您的代码时，它不起作用。是否可以将您的更改添加到我的代码中，以便我可以复制粘贴并区分更改？否则很难跟上变化，对我来说更容易出错。
贴出完整代码。它有两行被注释掉并且对我来说工作正常。我还注意到，当网格不在焦点时（第一个单元格中的数字变为黑色），您选择的网格行的行为会有所不同。我不知道你是否也想解决这个问题，但可以查看stackoverflow.com/questions/40710351/…。希望这会有所帮助！
非常感谢它有效！顺便说一句，为什么选定的行看起来也发生了变化？是否也可以解决这个问题？我发布了关于它但没有回复。

【解决方案2】：

您制作了所有内容 - DataGridRow.Background、DataGridCell.Background - 透明

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

要解决此问题，请在 IsSelected 触发器中删除背景设置器：

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

它将确保以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>

【讨论】：

谢谢我试过了，但它不起作用。实际上我不得不更改 OP 代码，因为在某些单元格上还会发生另一种背景颜色。
所以不确定为什么选择使用备用背景颜色，但如果没有选择，则使用单个单元格背景。
@JoanVenge，另一个 bg 仅适用于一列。在<Style TargetType="DataGridCell">中尝试<Setter Property="Background" Value="Transparent" />
谢谢，我刚试过，但它的颜色与您的示例中删除透明 bg 的颜色相同。
