WPF：固定文档在Visual Studio 2008设计 [英] WPF: FixedDocument in Visual Studio 2008 Designer

问题描述

这是 是Visual Studio的一个众所周知的漏洞显示了一个错误，当您尝试构建固定文档在XAML。例如，下面的片段

It's a well-known bug that Visual Studio shows an error when you try to construct a FixedDocument in XAML. For example, the following snippet

<DocumentViewer>
    <FixedDocument>
        <PageContent>
            <FixedPage Width="21.0cm" Height="29.7cm">
                <TextBlock>Hello World!</TextBlock>
            </FixedPage>
        </PageContent>
    </FixedDocument>
</DocumentViewer>

编译和运行完全正常，但Visual Studio中显示错误列表中的错误（属性页不支持类型PageContent的值。）这是很烦人的。

我正在寻找一个解决方案，让我建立我在Visual Studio中的XAML文件，文件没有得到该错误消息。我已经找到了解决办法，我想作为一个答案下面分享，但我很好奇，如果有围绕一个更好的（更优雅）的解决方案。

I'm looking for a solution that allows me to construct my documents in a XAML file in Visual Studio without getting that error message. I've found a workaround, which I'd like to share below as an answer, but I'm curious if there's a better (more elegant) solution around.

推荐答案

我知道这已经回答了，但我想这个答案是更好，因为它不要求你添加一个DocumentView。

I know this had already been answered, but I think this answer is nicer because it doesn't require you to add a DocumentView.

如果有一种方法通过密钥名称引用的资源，并把它们与XAML的固定文档，请让我知道。我似乎无法找到一个方法来做到这一点，但也许这是可能的。

If there's a way to reference the resources by the key name and put them in the FixedDocument with XAML, please let me know. I can't seem to find a way to do that, but maybe it's possible.

使用：

var doc = System.Windows.Application.LoadComponent(new Uri("/FixedDocumentExample.xaml", UriKind.Relative)) as FixedDocument;
doc.AddPages();

扩展方法：

using System.Collections;
using System.Windows.Documents;

public static class FixedDocumentExtended {
    public static void AddPages(this FixedDocument fixedDocument) {
        var enumerator = fixedDocument.Resources.GetEnumerator();
        while (enumerator.MoveNext()) {
            var pageContent = ((DictionaryEntry)enumerator.Current).Value as PageContent;
            if (pageContent != null) {
                fixedDocument.Pages.Add(pageContent);
            }
        }
    }
}

XAML：

XAML:

<FixedDocument
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <FixedDocument.Resources>
        <PageContent x:Key="page1">
            <FixedPage Width="793.76" Height="1122.56">
                <TextBlock Margin="50" Text="Page 1"/>
            </FixedPage>
        </PageContent>
        <PageContent x:Key="page2">
            <FixedPage Width="793.76" Height="1122.56">
                <TextBlock Margin="50" Text="Page 2"/>
            </FixedPage>
        </PageContent>
    </FixedDocument.Resources>
</FixedDocument>
