字典資源和綁定

Question

我需要從代碼訪問邊界刷，如何綁定？

這不行：

BorderBrush="{Binding color}" 

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

這裏我的XAML。

<UserControl x:Class="window6.Kbd"

Answer 1

喜歡這個？

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

如果您需要綁定到另一個屬性，那麼：

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

[編輯]嘗試3 :)

不知道我完全理解，但是這可能是你是什麼尋找：

BorderBrush="{TemplateBinding BorderBrush}" 

現在設置BorderBrush您RepeatButton和它的 應該管用。
