Adding the columns dynamically in crystal report

Question

Hi,
  I am developing a application using asp.net and crystal report. In a report the column is created dynamically( ie, the report gets input from a sp which returns N no. of columns). Since i dont know the column name and no. of columns at design time i am not able to create the report. If any of you have any idea on adding the columns dynamically please send me the code or the link.
Thanks

Hello Sankar,
please see CS code for VS 2005 below to add a database field to a report using inproc RAS.
This sampels retrieves the table column name from the database and adds it to the report.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.DataDefModel;
namespace CS_Add_Field_inproc
    public partial class Form1 : Form
        // CR Declarations
        ReportDocument boReportDocument;
        ISCDReportClientDocument boReportClientDocument;
        CrystalDecisions.ReportAppServer.ReportDefModel.Section boSection;
        CrystalDecisions.ReportAppServer.ReportDefModel.FieldObject boFieldObject;
        public Form1()
            InitializeComponent();
            //Create a new ReportDocument
            boReportDocument = new ReportDocument();
            // load the RPT file
            boReportDocument.Load("..
AddField.rpt");
            //Access the ReportClientDocument in the ReportDocument (EROM bridge)
            boReportClientDocument = boReportDocument.ReportClientDocument;
            //Get the first section in the details section
               boSection = boReportClientDocument.ReportDefController.ReportDefinition.DetailArea.Sections[0];
               //Create the field object that we will add to the report and set all of its properties
               boFieldObject = new CrystalDecisions.ReportAppServer.ReportDefModel.FieldObject();
            //Set which field to use for the data to be displayed
               boFieldObject.DataSourceName = "{Customer.City}";
               boFieldObject.FieldValueType = CrystalDecisions.ReportAppServer.DataDefModel.CrFieldValueTypeEnum.crFieldValueTypeStringField;
               boFieldObject.Left = 4 * 1440; //1440 twips per inch
               boFieldObject.Width = 3 * 1440;
               boFieldObject.FontColor = new CrystalDecisions.ReportAppServer.ReportDefModel.FontColor();
               boFieldObject.FontColor.Font.Name = "Arial";
               boFieldObject.FontColor.Font.Size = 10;
               boFieldObject.Format.HorizontalAlignment = CrystalDecisions.ReportAppServer.ReportDefModel.CrAlignmentEnum.crAlignmentLeft;
               //Add the object to the report
               boReportClientDocument.ReportDefController.ReportObjectController.Add(boFieldObject, boSection, -1);
            // show in reportviewer
            crystalReportViewer1.ReportSource = boReportDocument;
        private void button1_Click(object sender, EventArgs e)
            //Get the first section in the details section
            boSection = boReportClientDocument.ReportDefController.ReportDefinition.DetailArea.Sections[0];
            //Create the field object that we will add to the report and set all of its properties
            boFieldObject = new CrystalDecisions.ReportAppServer.ReportDefModel.FieldObject();
            //Set which field to use for the data to be displayed
            boFieldObject.DataSourceName = "{Customer.City}";
            boFieldObject.FieldValueType = CrystalDecisions.ReportAppServer.DataDefModel.CrFieldValueTypeEnum.crFieldValueTypeStringField;
            boFieldObject.Left = 4 * 1440; //1440 twips per inch
            boFieldObject.Width = 3 * 1440;
            boFieldObject.FontColor = new CrystalDecisions.ReportAppServer.ReportDefModel.FontColor();

            boFieldObject.Format.HorizontalAlignment = CrystalDecisions.ReportAppServer.ReportDefModel.CrAlignmentEnum.crAlignmentLeft;
            //Add the object to the report
            boReportClientDocument.ReportDefController.ReportObjectController.Add(boFieldObject, boSection, -1);
            // show in reportviewer
            crystalReportViewer1.ReportSource = boReportDocument;
