Question

我需要从代码访问borderbrush，怎么绑定？

这不起作用：

BorderBrush="{Binding color}"

<Border x:Name="brd"  Background="Black" BorderBrush="White" BorderThickness="2" CornerRadius="3">

这是我的xaml。

<UserControl x:Class="window6.Kbd"
         x:Name="teclado"

喜欢这个吗？

brd.BorderBrush = new SolidColorBrush(Colors.Blue);

如果您需要绑定到另一个属性，那么：

brd.SetBinding(Border.BorderBrushProperty, new Binding("SomeProperty") { Source = someObject });

[编辑]尝试＃3：）

我不确定我完全理解，但这可能就是你要找的东西：

BorderBrush="{TemplateBinding BorderBrush}"

现在设置BorderBrush的{{1}}，它应该有效。
