Question

我有一个使用自定义窗口控件的程序。在VS2013中，窗口在设计视图中渲染得很好，与VS2015中打开的解决方案完全相同。在运行时编译并正常工作。

相关代码的片段在这里：

<control:CustomWindow x:Class="CategoryView"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:control="clr-namespace:ClassAccounts;assembly=ClassAccounts"
    xmlns:l="clr-namespace:WpfAccounts"
    Title="Category" Width="470" Height="485" WindowStartupLocation="CenterScreen" OKVisibility="True">

<Window.Resources>

    <CollectionViewSource Source="{Binding Categories}" x:Key="Categories"/>
    <CollectionViewSource Source="{Binding Headings}" x:Key="Headings"/>

    <DataTemplate x:Key="CategoryTemplate">
        <TextBlock Text="{Binding comment}" Margin="0" Foreground="{Binding forecolor}"/>
    </DataTemplate>
</Window.Resources>

<Grid>
    ...
</Grid>

        <!-- Region SubMenu -->

感谢任何帮助。安迪

Answer 1

我发现了一些事情。我注意到在我发布的示例项目中，实际上它在VS2013中无法正确呈现。 Generic.xaml的关键是：

<Style TargetType="{x:Type local:CustomWindow}" x:Key="{x:Type local:CustomWindow}">

如果我将其更改为：

<Style TargetType="{x:Type local:CustomWindow}">

它在VS2013中渲染得很好（但仍然没有在VS2015中）。理论上（来自MSDN）这不应该产生差异，因为x：如果没有指定，Key是隐式的。

如上面的第一个示例所示，将TargetType属性设置为TextBlock而不使用x：Key指定样式允许将样式应用于所有TextBlock元素。实际发生的是，这样做会隐式地将x：Key设置为{x：Type TextBlock}。这也意味着如果您为Style赋予除{x：Type TextBlock}之外的任何内容的x：Key值，则Style将不会自动应用于所有TextBlock元素。相反，您需要明确地将样式应用于TextBlock元素。

（来自https://msdn.microsoft.com/fr-fr/library/ms745683(v=VS.85).aspx#styling_targettype）

似乎在VS2015中修复它（虽然它有点软糖）正在改变它：

<Style TargetType="{x:Type local:CustomWindow}" x:Key="CustomWindow">

并添加

<Style="{DynamicResource CustomWindow}">

到主项目中的每个窗口xaml。我认为我不应该这样做，我认为VS2013和VS2015都可能存在错误，因为前两个中的任何一个都应该有效。

感谢任何想法并感谢目前为止的投入。安迪

Answer 2

我正在做类似于你的事情，我的VS2015正常工作，我在设计师看到了我的风格窗口。我的设置略有不同。

的App.xaml：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/xxx.yyy;component/Themes/Generic.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

请注意不同的路径语法。我提到这一点是因为我在控件上遇到了相反的问题。出于某种原因，在一个窗口中，设计人员不会选择使用/xxx.yyy ;component语法的资源。当我将其切换为打包语法时，设计师能够看到资源。

就像我说的，我有一个自定义窗口（框架，客户端，一切都被覆盖）。设计师正在展示风格版本。

另外，我的generic.xaml类似。它只包含其他xaml文件：

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="/xxx.yyy;component/Themes/xxxWindow.xaml" />

Answer 3

我在VS 2015 Update 2中遇到了这个问题。我安装了Update 3，它解决了这个问题。

VS2015在设计视图中不渲染自定义窗口控件（适用于VS2013）
