BasedOn=“{StaticResource{x:Type TextBlock}”的Silverlight 3.0等价物是什么

{x:Type SomeType} 因为钥匙不起作用。

在Silverlight中,您需要制作控件样式的完整副本。您可以通过使用Blend来实现这一点,Blend有用于实现这一点的工具,或者从Silverlight文档中复制粘贴它。 Control Styles and Templates

当然,一旦有了初始样式的副本,就可以修改副本或创建其他样式,将此副本指定给BasedOn以创建一组变体。

我认为稍微后退一点会有用的,你可以做你的基本风格

<Style TargetType="Button" x:Key="MyButtonStyle">
    <Setter Property="PropertyName" Value="PropertyValue" />
</Style>

然后,您可以基于该样式创建所有按钮

<Style TargetType="Button" BasedOn="{StaticResource MyButtonStyle}" />

<Style TargetType="Button" BasedOn="{StaticResource MyButtonStyle}">
    <Setter Property="PropertyName" Value="PropertyValue" />
</Style>

或

<Style TargetType="Button" BasedOn="{StaticResource MyButtonStyle}" x:Key="MyOtherButtonStyle">
    <Setter Property="PropertyName" Value="PropertyValue" />
</Style>

according to Jesse Liberty )
BasedOn="{StaticResource TextBlock}"

您现在可以在Silverlight 5中实际执行此操作。

首先,宣布你的风格

<Style x:Key="TextBoxStyle" TargetType="TextBox" BasedOn="{local:Type TypeName=TextBox}">

</Style>

接下来,您需要创建一个在WPF和Silverlight 5中都能工作的MarkupExtension来替换x:Type

    public String TypeName { get; set; }

    public override Object ProvideValue(IServiceProvider serviceProvider)
    {
        if (Type == null)
        {
            if (String.IsNullOrWhiteSpace(TypeName)) throw new InvalidOperationException("No TypeName or Type specified.");
            if (serviceProvider == null) return DependencyProperty.UnsetValue;

            IXamlTypeResolver resolver = serviceProvider.GetService(typeof(IXamlTypeResolver)) as IXamlTypeResolver;
            if (resolver == null) return DependencyProperty.UnsetValue;

            Type = resolver.Resolve(TypeName);
        }
        return Type;
    }
}
