C#-ReportViewer-使类不是静态的

我有一个类DependencyReportViewer，它对应于在程序中创建ReportViewer控件。这门课学得很好。在XAML中，我们只为想要的每个报告定义这一行：

  <ctr:DependencyReportViewer EmbeddedReportName="Program.View.Reports.ReportName.rdlc" ReportData="{Binding ReportData}"/>

课程的第一部分：

问题是，此代码仅在只有一个UserControl打开此ReportViewer的情况下正常工作。如果我们打开两个或多个控件，那么最后一个打开的控件将接管ReportViewer。换句话说，可以同时只打开一个ReportViewer

现在，我想有一个可能打开多个控件与多个报告查看器。我得到的问题是这个类是静态的。当我们定义一个新控件时，在“this.Child=DependencyReportViewer.ReportViewer；”行中，我们只是将这个查看器重置为最新的控件

---

但是写这篇文章的人比我现在有更高的技巧。我多次未能使用XamlParseException将此类设置为非静态。如何将该类转换为非静态？

另一个要考虑的选项是。它是一个WPF控件，一个免费的社区版本是可用的。它是一个WPF控件，提供免费的社区版本。
