这是ReportSourceBehaviour:

命名空间Wpf_Mvvm_CrystalReport.Reports
 {
     公共静态类ReportSourceBehaviour
     {
         公共静态只读System.Windows.DependencyProperty ReportSourceProperty =
         System.Windows.DependencyProperty.RegisterAttached(
             " ReportSource",
             typeof(对象),
             typeof(ReportSourceBehaviour),
             新的System.Windows.PropertyMetadata(ReportSourceChanged));


         私有静态无效ReportSourceChanged(System.Windows.DependencyObject d,System.Windows.DependencyPropertyChangedEventArgs e)
         {
             var crviewer = d作为SAPBusinessObjects.WPF.Viewer.CrystalReportsViewer;
             如果(crviewer!= null)
             {
                 crviewer.ViewerCore.ReportSource = e.NewValue;
             }
         }


         公共静态无效SetReportSource(System.Windows.DependencyObject目标,对象值)
         {
             target.SetValue(ReportSourceProperty,value);
         }


         公共静态对象GetReportSource(System.Windows.DependencyObject target)
         {
             返回target.GetValue(ReportSourceProperty);
         }
     }
 }
 

这是MainWindow.xaml:

         xmlns =" http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x =" http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:d =" http://schemas.microsoft.com/expression/blend/2008"
         xmlns:mc =" http://schemas.openxmlformats.org/markup-compatibility/2006"
         xmlns:local =" clr-namespace:Wpf_Mvvm_CrystalReport.Views"
         xmlns:Viewer =" clr-namespace:SAPBusinessObjects.WPF.Viewer; assembly = SAPBusinessObjects.WPF.Viewer" x:Class =" Wpf_Mvvm_CrystalReport.Views.MainWindow"
         mc:Ignorable =" d"
         xmlns:dd =" clr-namespace:Wpf_Mvvm_CrystalReport.ViewModels"
         d:DataContext =" {d:DesignInstance dd:MainWindowViewModel,IsDesignTimeCreatable = True}"
         xmlns:prism =" http://prismlibrary.com/"
         棱镜:ViewModelLocator.AutoWireViewModel =" True"
         xmlns:rpt =" clr-namespace:Wpf_Mvvm_CrystalReport.Reports"
         Title =" MainWindow" Height =" 300" Width =" 300">
     <网格>
         
             
             
         
         
             
             
         
         
     
 


 

这是MainWindowViewModel.cs:

使用CrystalDecisions.CrystalReports.Engine;
 使用Prism.Mvvm;
 使用Wpf_Mvvm_CrystalReport.Reports;
 命名空间Wpf_Mvvm_CrystalReport.ViewModels
 {
     类MainWindowViewModel:BindableBase
     {
         公共ReportDocument报告{ 组;  }
         私人ushort _Flow = 2;
         公共超短流
         {
             得到{return _Flow;  }
             设置{SetProperty(ref _Flow,value);  }
         }
         公共MainWindowViewModel()
         {
             报告=新的CrystalReport1();
         }
     }
 }
