使用Silverlight 4，我们似乎无法让Childwindows显示隐式样式。我们的app上的每个其他控件都采用隐式样式，但是子窗口（甚至子窗口上的控件都采用隐式样式）
（我们正在使用工具包样式）

答案 0 :(得分：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)。
从“ChildWindow”继承自己的类，并在构造函数中设置以下内容：
DefaultStyleKey = typeof(MyChildWindow);
或者通过创建“键”并在子窗口控件上应用该样式键来使用显式样式。

Color="{StaticResource ExpressionBottomGradientBrush2}"
请注意，如果将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，它就不适用，我想这就是您无法看到它的原因。 ：）
