Runtime acces to Group Supress Formula

Question

Hello,
I'm using Crystal Reports 2008.
I want to remove a supress formula in runtime from a given group/section.
I can only access to a readonly object (ReportDefController) where these formula is defined.
Dim objGroupSection As CrystalDecisions.ReportAppServer.ReportDefModel.Section
                For Each objGroupSection In m_objReport.ReportClientDocument.ReportDefController.ReportDefinition.GroupFooterArea(intGroupNumber).Sections
                    objGroupSection.Format.ConditionFormulas.RemoveAll()
                Next
                For Each objGroupSection In m_objReport.ReportClientDocument.ReportDefController.ReportDefinition.GroupHeaderArea(intGroupNumber).Sections
                    objGroupSection.Format.ConditionFormulas.RemoveAll()
                Next
                'm_objReport.ReportClientDocument.ReportDefController.ReportStyle
                m_objReport.ReportClientDocument.ReportDefController.ReportDefinition.GroupFooterArea(1).Sections(0).Format.ConditionFormulas.RemoveAll()
What am I doing wrong? Is there any other way of accessing these object ?

Jos,
Yes you can do what you are attempting to accomplish. You'll want to use the ReportSectionController's SetProperty method to change the entire SectionFormat object.
See the code below for a small sample of what you need to do.
ISCDReportClientDocument boReportClientDocument;
boReportDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
boReportDocument.Load(Server.MapPath("CrystalReport.rpt"));
boReportClientDocument = boReportDocument.ReportClientDocument;
// Get the section that needs to be modified
CrystalDecisions.ReportAppServer.ReportDefModel.Section boSection = boReportClientDocument.ReportDefinition.Areas[0].Sections[0];
// Clone the SectionFormat so changes can be made
CrystalDecisions.ReportAppServer.ReportDefModel.SectionFormat boSectionFormat = boSection.Format.Clone(true);
// Get the ReportSectionController
CrystalDecisions.ReportAppServer.Controllers.ReportSectionController boReportSectionController = boReportClientDocument.ReportDefController.ReportSectionController;       
// Change the condition formula to its new value
boSectionFormat.ConditionFormulas[CrystalDecisions.ReportAppServer.ReportDefModel.CrSectionAreaFormatConditionFormulaTypeEnum.crSectionAreaConditionFormulaTypeEnableSuppress].Text = "false;";
// Use the SetProperty method on the section controller to modify the crReportSectionPropertyFormat
boReportSectionController.SetProperty(boSection, CrystalDecisions.ReportAppServer.Controllers.CrReportSectionPropertyEnum.crReportSectionPropertyFormat, boSectionFormat);
CrystalReportViewer1.ReportSource = boReportDocument;
