Silverlight 子窗口 +隐式样式不起作用

Question

使用 Silverlight 4，我们似乎无法让 Childwindows 显示我们的隐式样式。我们应用程序上的所有其他控件都采用隐式样式，但子窗口（甚至子窗口上的控件也采用其隐式样式）

（我们正在使用工具包样式）

Answer 1

这似乎是 Silverlight 4 的一个问题，因为默认样式键未设置为 typeof(ChildWindow)。

要么从“ChildWindow”继承您自己的类，并在构造函数中设置以下内容：

DefaultStyleKey = typeof(MyChildWindow);

或者通过创建“键”并在“键”上应用该样式键来使用显式样式。子窗口控件。

Answer 2

Color="{StaticResource ExpressionBottomGradientBrush2}"

请注意，如果 ExpressionBottomGradientBrush2 定义为 System.Windows.Media.SolidColorBrush，则无法将其设置为 System.Windows.Media.Color。

如果您的子窗口样式有任何错误，它就不会适用，我想这就是您看不到它的原因。 :)
