setter属性到Code Behind属性颜色的绑定值

Question

我正在努力寻找一种方法来设置Setter。值与我自己的属性(SelectedRowBackColor)。这行XAML不起作用:

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

有人能帮我一下吗?谢谢。

</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:我注意到这个解决方案只适用于Windows 10，它无法设置Windows 7的颜色:

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

Answer 1

我知道Windows 7和Windows 10使用不同的方法，所以我实现了两者，以达到相似的结果:

<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>
