  Hello,
  
  I was wondering if there is a save way to detect if “myinfo” exists in the rpx script when you preview from the End User Report Designer?
  
  When I run my app I load the report with
  
  rpt.LoadLayout(xtr)
  
  and then
  
  rpt.AddNamedItem(“myInfo”, myObject)
  
  and then I call “myInfo” when the report is running.
  
  However in End User Report Designer preview I don’t want to call “myInfo”. Is there a way to tell if “myInfo” does not yet exist or maybe if I am in preview mode?
  
  Thanks
  
  Brian

  Hello Brian,

  Sorry to mention that I don’t understand your actual requirement.

  What I understand, you are loading the report layout in your application and use the following code to add class reference:

   rpt.AddNamedItem("myInfo", myObject)
  

  After that, you saved the report layout using “SaveLayout” method of section report.
  
  Use the 'GrapeCity.ActiveReports.Designer.exe" (End User Designer)(located at C:\Program Files (x86)\GrapeCity\ActiveReports 12\Tools) to preview the report.

  And you want to detect if “myinfo” exists in the RPX script at the time of preview in above exe. If yes, then “rpt.AddNamedItem(“myInfo”, myObject)” is never saved in your RPX layout. You need to add it through code always to use the “myinfo” in your report. Hence, there is no reference of “myinfo” exists when you preview the report in End User designer

  If my understanding is incorrect, please explain in detail.

  Thanks,

  Mr Mohitg,
  
  Not quite. Let me explain another way.
  
  The rpx report is created using the End User Designer.
  
  There is some script that references “myInfo” so that when my app loads the rpt and runs it, the report uses the part of the script that references “myInfo” and everythings happens as it should.
  
  When you try preview in EUD obviously “myInfo” does not exist so you correctly get a script error.
  
  What I would like is to detect that I am in preview mode so that I can put script to test and bypass the part of the script that references “myInfo” and thus get to see the preview without having to manually comment-out the references to “myInfo”.
  
  Regards
  
  Brian

  Hello,

  For this, you need to customize the EUD. You need to handle the “DesignerTabChanged” event of the designer to change the script at the time of preview. Please refer to the following lines of code;

  
  Private Sub reportDesigner_DesignerChanged(sender As Object, e As DesignerTabChangedEventArgs)
          If reportDesigner.ReportType = DesignerReportType.Section Then
              If e.ActiveTab = DesignerTab.Preview Then
                  'Change the script here
                  CType(reportDesigner.Report, SectionReport).Script = ""
                  'To reload the report with new script
                  reportDesigner.ReportViewer.LoadDocument(reportDesigner.Report)
              End If
          End If
      End Sub
  
  

  Also, you can refer the attached sample for implementing the same.

  Hope it helps.

  Thanks,

  Mr Mohitg,
  
  Oh, ok. I follow. The default designer is perfect for me so I did not think to change it. I will have a go at it.
  
  Thanks
