Reorder or hide columns when exporting

Question

Hello,
When woking with Reports and previewing it before sent to the client, may appear the desire to change the report before sanding.
by ex, one of our customers says: "This would be a nice extension of the column hiding & reordering capability, and would help with customers' requests that their reports come with certain data "eliminated."
I work mainly with the CrstalReports "ReportClass:ReportDocument" class.
Well, is there a possibility to hide some columns (when exporting)? To reorder them?
thanks.

Hello,
you could delete report fields and runtime without saving the report.
I attach code below for CS in VS2005:

        public Form1()
            InitializeComponent();
            //Create a new ReportDocument
            boReportDocument = new ReportDocument();
            // load the RPT file
            boReportDocument.Load("..
DeleteField.rpt");
            //Access the ReportClientDocument in the ReportDocument (EROM bridge)
            boReportClientDocument = boReportDocument.ReportClientDocument;
            // show in reportviewer
            crystalReportViewer1.ReportSource = boReportDocument;
        private void button1_Click(object sender, EventArgs e)
            //find the object in the report
            boReportObject = (CrystalDecisions.ReportAppServer.ReportDefModel.ReportObject) boReportClientDocument.ReportDefController.ReportDefinition.FindObjectByName("City1");;
            //Delete the object from the report
            boReportClientDocument.ReportDefController.ReportObjectController.Remove(boReportObject);
            //show in reportviewer
            crystalReportViewer1.ReportSource = boReportDocument;
        private void button2_Click(object sender, EventArgs e)
            //save report with new title
            boReportDocument.SaveAs("Test.rpt");
