[UWP]主题自定义控件，Generic.xaml样式未应用于设计器中。 [英] [UWP] Themed Custom Control, Generic.xaml style is not applied in designer.

问题描述

您好

我正在尝试创建一个可以重复使用的UWP控件。它位于一个控件库中，其样式为Themes / Generic.xaml。

I'm trying to create an UWP control that I can reuse. It lives in a control library with a style in Themes/Generic.xaml.

如果我将应用程序项目中的控件添加到我的MainPage.xaml中。设计器（VS和Blend）只显示控件的位置，但实际上并没有使用Generic.xaml中定义的样式。

If I add that control in the application project to my MainPage.xaml. The designer (VS and Blend) only shows an outline of where the control is, but does not actually use the style that is defined in Generic.xaml.

但是如果我运行程序那么它会正确显示。

However if I run the program then it gets displayed correctly.

让设计师知道如何找到并应用该风格的正确方法是什么？

What's the correct way of letting the designer know how to find and apply that style?

谢谢，

Markus

Hi Tokter，

Hi Tokter,

>>" What's the correct way of letting the designer know how to find and apply that style?"

根据我的经验，你可以使用"ms-appx：///"从app包中获取样式文件。我为您制作了一个代码示例。

In my experience, you could use "ms-appx:///" to get the style file from app package. I have made a code sample for you.

请参考我的以下代码示例和屏幕截图以供参考：

Please refer to my following code sample and screenshot for reference:

    <Style TargetType="Button">
        <Setter Property="Background" Value="Red"></Setter>
    </Style>
</ResourceDictionary>
