C# – Programmatically hide text/lines in a Crystal Report

ccrystal-reports

I have a Crystal Report that I populate before displaying to the user using a CrystalReportViewer.

I have some static text items and line segments that I would like to show and hide programatically depending on conditions in the business logic. Is there a way I can group a bunch of these items together and hide them as a group?

At the moment, my other option is to have two separate reports that are identical except for these superficial differences.

By all means, please don't create two separate reports :)

In the Report Design view, you should be able to create sub-sections of your detail section (assuming you're talking about the detail section), right-clicking on the Detail section and selecting "Insert Section Below".

You should now have "Details a" and "Details b" sections. You can put your text in the "Details b" section, and apply a conditional suppression formula to it.

To conditionally suppress the "Details b" section, right-click on it in the Design View, select "Format section...", click on the button next to the "Suppress" checkbox, and add your formula there.

R – Override the Refresh Crystal Report that brings up their criteria page

You don't say which version of Visual Studio or Crystal Reports, but the Viewer control should have a property called ShowRefreshButton.

Alternatively, there is also a ReportRefresh event which will fire when you click the button, but I think this will be fired when you initially load the report as well so you'll need to selectively override it by setting e.Handled to True.

C# – Generate Crystal Report ‘on the fly’

This isn't exactly what you are looking for... but this is a code snippet that we use to generate PDF copies of Crystal Reports on the fly.

Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared

Using rpt As New ReportDocument()
  With rpt
    .Load("/Path/To/RTPFile.rpt", OpenReportMethod.OpenReportByTempCopy)
    .SetDataSource(dataSource)
    .ExportToDisk(ExportFormatType.PortableDocFormat, "/Path/To/Report.pdf")
  End With
  rpt.Close()
End Using

In this case 'datasource' is an XSD Dataset that has been loaded with the report data ready-to-go.
