将 setter 属性的值绑定到 Code Behind 属性颜色答案

【问题标题】：Binding value of a setter property to a Code Behind Property Color将 setter 属性的值绑定到 Code Behind 属性颜色
【发布时间】：2021-10-16 10:25:55
【问题描述】：

我正在努力寻找一种方法来使用我自己的属性 (SelectedRowBackColor) 设置 Setter.Value。这行 XAML 不起作用：

<SolidColorBrush Color="{Binding XPath=SelectedRowBackColor}"></SolidColorBrush>

有人可以帮帮我吗？谢谢。

                </MenuItem>
            </ContextMenu>
        </ListView.ContextMenu>
    </ListView>
</UserControl>

这是属性：

private System.Windows.Media.Color? m_SelectedRowBackColor = System.Windows.Media.Color.FromArgb(255, 0x0A, 0x24, 0x6A);    //Colore di selezione originale

[Category("Properties")]
[Description("Selected Row Background Color")]
public System.Windows.Media.Color? SelectedRowBackColor
{
    get
    {
        return m_SelectedRowBackColor;
    }
    set
    {
        m_SelectedRowBackColor = value;
    }
}

编辑：我注意到此解决方案有效，但仅适用于 Windows 10，无法在 Windows 7 上设置颜色：

<SolidColorBrush Color="{Binding SelectedRowBackColor, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}"></SolidColorBrush>

【解决方案1】：

我了解 Windows 7 和 10 使用不同的方法，因此我实现了两者以在两者中实现相似的结果：

<ListView.Resources>
    <!-- Windows 7 -->
    <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="{Binding SelectedRowBackColor, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}" />
    <SolidColorBrush x:Key="{x:Static SystemColors.ActiveBorderBrushKey}" Color="{Binding SelectedRowBackColor, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}" />
    <!-- Windows 10 -->
    <Style TargetType="{x:Type ListViewItem}">
        <Style.Triggers>
            <Trigger Property="IsSelected" Value="True">
                <Setter Property="Background">
                    <Setter.Value>
                        <SolidColorBrush Color="{Binding SelectedRowBackColor, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}"></SolidColorBrush>
                    </Setter.Value>
                </Setter>
                <Setter Property="BorderBrush">
                    <Setter.Value>
                        <SolidColorBrush Color="{Binding SelectedRowBackColor, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}"></SolidColorBrush>
                    </Setter.Value>
                </Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
</ListView.Resources>
