Wpf 应用于日期选择器的按钮样式
我在Wpf 应用于日期选择器的按钮样式,wpf,datepicker,dropshadoweffect,Wpf,Datepicker,Dropshadoweffect,我在App.xaml中声明了默认按钮样式。它已应用阴影效果。奇怪的是DropShadowEffect也被应用到了DatePicker 任何人都可以帮助删除日期选择器中的DropShadowEffect吗？这是因为日期选择器控件使用您定义的标准（默认）按钮模板。我遇到了同样的问题，我的默认按钮样式弄乱了我所有的日期选择器的外观。有两种方法可以解决此问题： 解决方案1:（不理想） 为默认样式添加一个键，并将其应用于应用程序中应使用该键的所有按钮。这个解决方案对我来说是不可能的，因为我特别希望样式覆盖
App.xamlDatePicker任何人都可以帮助删除日期选择器中的DropShadowEffect吗？这是因为日期选择器控件使用您定义的标准（默认）按钮模板。我遇到了同样的问题，我的默认按钮样式弄乱了我所有的日期选择器的外观。有两种方法可以解决此问题： 解决方案1:（不理想） 为默认样式添加一个键，并将其应用于应用程序中应使用该键的所有按钮。这个解决方案对我来说是不可能的，因为我特别希望样式覆盖默认值。所以 解决方案2:（首选但有点痛苦的方式） 右键单击xaml设计器中的控件，覆盖App.xaml（或styles.xaml）文件中的默认按钮和日期选择器样式->编辑模板->编辑副本… 向新添加的按钮样式添加一个键，称为DefaultWpfButtonStyle（确保默认情况下不会使用它），然后将该样式应用于DatePicker样式/模板内的按钮控件。这将确保DatePicker为应用程序中的下拉按钮使用默认WPF按钮样式，而不是默认样式 或者，您可以复制粘贴以下代码：
