Wpf 打印时DataGrid列未调整大小

我有一个从传感器获取数据的应用程序，然后从该数据输出图形和数据网格

什么有效： 我正在生成一个带有usercontrol的报告，该报告插入到一个fixedPage中，在DocumentViewer的帮助下显示在FixedDocument中

我当时所做的： 为了简化很多事情，比如启用文本搜索、预生成报告等等，我决定将我的FixedDocument转换为XpsDocument，并将其放入DocumentViewer

我的问题： 出于某种原因，除了我的DataGrid列之外，所有内容都通过转换保持不变。我正在用Xaml手动插入我的列，每个列的宽度为1*。但我得到的结果是，它似乎完全忽略了调整大小。它甚至不能根据内容正确调整大小

什么修复了它：当我放置一个固定的宽度时，它在查看器中受到尊重

代码：

var actualReport = new FixedDocument();
actualReport.DocumentPaginator.PageSize = new Size(8.5 * 96, 11 * 96);
actualReport.Pages.Add(new PageContent { Child = new FixedPage { Children = {
            new FrontPage { Width = 8.5 * 96, Height = 11 * 96, DataContext = d, }
        }
    }
});

[.. Three more pages ..]

var ms = new MemoryStream();
var pkg = Package.Open(ms, FileMode.Create, FileAccess.ReadWrite);

string pack = "pack://temp.xps";
PackageStore.AddPackage(new Uri(pack), pkg);

var doc = new XpsDocument(pkg, CompressionOption.SuperFast, pack);
XpsSerializationManager rsm = 
    new XpsSerializationManager(new XpsPackagingPolicy(doc), false);
rsm.SaveAsXaml(actualReport.DocumentPaginator);
Viewer.Document = doc.GetFixedDocumentSequence();

我也遇到了同样的问题。你找到解决办法了吗？@Balls of steel有更新吗？
