第一个风格XAML工程，我想，生产用setter方法奠定了内容的狂怒字形按钮和它的属性。这种风格的第二个版本是试图做同样的事情，但与内容一个DataTemplate，但它只是显示一个DataTemplate（即System.Windows.DataTemplate）的类型。

为什么不会在第二版显示相同的内容，第一？
假定修复是微不足道的，将风格的一个版本以任何理由超越个人喜好超过其他适合？

注：我显示了绑定，并在触发的情况下有东西在那里，是影响的内容，但它只是说改变风格的第一部分

干杯，

            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

你的Content属性设置为一DataTemplate

DataTemplates旨在与其一起使用Template的属性，并通过不直接插入的VisualTree Content属性

改变你的风格二传手设定ContentTemplate ，而不是Content ，它应该正常工作

<Setter Property="ContentTemplate">
    <Setter.Value>
        <DataTemplate>
            <TextBlock Text="a" FontFamily="Wingdings 3" FontWeight="Bold" FontSize="18" Foreground="Navy" />
        </DataTemplate>
    </Setter.Value>
</Setter>

至于你的第二个问题，我更喜欢第一个，因为它的简单，我认为它可能包含在Visual树较少的元素（我不得不仔细检查）
