  I am trying to follow the example in the blog posting for ActiveReports 8 (https://www.grapecity.com/blogs/adding-exporting-functionality-to-wpf-viewer/) but there is no link to download the sample solution and the posted code seems to be missing some steps - no mention of how or where to define the “MainWindow.reportDocument”. I was able to get a little bit further when I found the forum posting here https://www.grapecity.com/forums/ar-dev/adding-exporting-to-wpf-vi. However, I am using version 12 not 7 and I also have it set up to where the user picks the report to load at runtime using a combobox and preview button.

  My problems:

  1. how to I set the value for reportDocument?
  2. how do I get the “PdfCommand” name to exist in the namespace “clr-namespace:AXReports”

  In my MainWindow.xaml.cs file I have the following:

  using System;
  using System.Windows;
  using System.Windows.Controls;
  
  namespace AXReports
  {
      /// <summary>
      /// 
      /// </summary>
      public partial class MainWindow : Window
      {
          static readonly string CurrentFileLocation = AppDomain.CurrentDomain.BaseDirectory + @"\Reports\";
          public static GrapeCity.ActiveReports.Document.PageDocument reportDocument { get; set; }
          public MainWindow()
          {
              InitializeComponent();
          }
          /// <summary>
          /// >Preview Button Click- Load selected report on click.
          /// </summary>
          /// <param name="sender"></param>
          /// <param name="e"></param>
          private void btnPreview_Click(object sender, RoutedEventArgs e)
          {
              ComboBoxItem _report = (ComboBoxItem)CmbListBox.SelectedItem;
              switch (_report.Content.ToString())
              {
                  case "AXDocOverview.rdlx":
                      ReportViewer.LoadDocument(CurrentFileLocation + _report.Content);
                      break;
                  case "AXGlobalUDLSpec.rdlx":
                      ReportViewer.LoadDocument(CurrentFileLocation + _report.Content);
                      break;
                  case "AXAppSpecReview.rdlx":
                      ReportViewer.LoadDocument(CurrentFileLocation + _report.Content);
                      break;
                  case "AXAppSpecSign.rdlx":
                      ReportViewer.LoadDocument(CurrentFileLocation + _report.Content);
                      break;
                  case "AXUserAccessRequestBasic.rdlx":
                      ReportViewer.LoadDocument(CurrentFileLocation + _report.Content);
                      break;
                  case "AXUserAccessRequestAdobeSign.rdlx":
                      ReportViewer.LoadDocument(CurrentFileLocation + _report.Content);
                      break;
              }
          }
          /// <summary>
          ///In the SelectionChanged event of the combo box, disable 'Preview' button, when no report is selected.
          /// </summary>
          /// <param name="sender"></param>
          /// <param name="e"></param>
          private void CmbListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
          {
              if (CmbListBox.SelectedIndex == 0)
              {
                  btnPreview.IsEnabled = false;
              }
              else
              {
                  btnPreview.IsEnabled = true;
              }
          }
      }
  }
  

  My PdfCommand.cs file has this:

  using System;
  using System.Windows;
  using System.Windows.Input;
  
  namespace AXReports
  {
      class PdfCommand : ICommand
      {
          public event EventHandler CanExecuteChanged;
  
          public bool CanExecute(object parameter)
          {
              return true;
          }
  
          public void Execute(object parameter)
          {
              GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport _exporter = new GrapeCity.ActiveReports.Export.Pdf.Section.PdfExport();
              _exporter.Export(MainWindow.reportDocument, "..\\..\\Test.pdf");
              MessageBox.Show("Exporting of Report to PDF Complete!");
          }
      }
  }
  

  My DefaultWPFViewerTemplates.xaml has this:

  <ResourceDictionary  ... xmlns:AXReports="clr-namespace:AXReports">
      <AXReports:PdfCommand x:Key="PdfCommand" />
  
  ...
  
    <!-- Custom buttons-->
    <Button Command="{StaticResource PdfCommand}" ToolTip="Export to PDF" >
      <StackPanel>
         <Image Source="Image\\pdf.gif" />
       </StackPanel>
    </Button>
  </ToolBar>

  Hello,

  Please refer to the attached sample to implement the same.

  1. how to I set the value for reportDocument?
     
     You can set the Report Document value as follow:
     
     case “AXUserAccessRequestAdobeSign.rdlx”:

    GrapeCity.ActiveReports.PageReport rpt = new GrapeCity.ActiveReports.PageReport();
                 rpt.Load(new System.IO.FileInfo(CurrentFileLocation + _report.Content);
                 rpt.Run();
                 GrapeCity.ActiveReports.Document.PageDocument MyDocument = new GrapeCity.ActiveReports.Document.PageDocument(rpt);
                 Viewer1.LoadDocument(MyDocument);
                 reportDocument = MyDocument;
   break;
  

  2. how do I get the “PdfCommand” name to exist in the namespace “clr-namespace:AXReports”
     
     On MainWindow.xaml before the opening tag, add the following code.

  <Window.Resources>                                
  <ResourceDictionary Source="DefaultWPFViewerTemplates.xaml" />
  </Window.Resources>
  

  Hope it helps.

  Thanks,
