When I run this line of code when it reaches the report.Render() that will show this error :

XAML:

    public partial class MainWindow : Window  
    {  
        public MainWindow()  
        {  
            InitializeComponent();  
        }  
  
        private void Window_Loaded(object sender, RoutedEventArgs e)  
        {  
            var report = new StiReport();  
            report.Load(@"D:\Myreport1.mrt");  
            report.Render();  
            rptviewer1.Report = report;  
        }  
    }

report.Render();  
report.ShowWithWpf();
