I created report in asp.net,c#

every time when i run the report it asks

Server Name,Database Name,User Name,Password

I have written the code given below

SqlConnection con = new SqlConnection(GetConnectionString());
con.Open();
try
{

string statement = " select a.CustomerNo,"
+ " CASE WHEN cd1.ContactType =1 "
+ " THEN cd1.CustomerName "
+ " ELSE cd1.CustomerName + ' / ' + cd1.CompanyName end as ContactDetails,"
+ " a.customerno,a.subject,a.mailto,cd1.companyname,"
+ " a.MeetingDate,a.MeetingType,a.subject,a.minutesofd iscussion,a.actiontaken ,"
+ " a.result,a.FollowupDate,a.FollowupAction,a.attendi es,a.Isactive,a.EmployeeName"
+ " from ( select customerno ,mailto,convert(varchar,fu.MeetingDate,105) as MeetingDate,"
+ " MeetingType,Subject,MinutesofDiscussion, Actiontaken,Result,FollowupDate,FollowupAction,"
+ " attendies,fu.Isactive,ud.EmployeeName from followup fu left outer join"
+ " userdetails ud on fu.mailto=ud.UNo) a,customerdetails cd1 where a.customerno= cd1.customerno";



string whereConcatenator = " And ";
if (Request.QueryString["prmCustomerNo"] != "0")
{
statement += whereConcatenator;
statement += "cd1.RelatedTo= " + Request.QueryString["prmCustomerNo"] + " ";
whereConcatenator = "AND ";
}


if (Request.QueryString["prmCustomerNo"] != "0")
{
statement += whereConcatenator;
statement += " a.CustomerNo = " + Request.QueryString["prmCustomerNo"] + " ";
whereConcatenator = "AND ";
}
if (Request.QueryString["prmCompanyNo"] != "0")
{
statement += whereConcatenator;
statement += " a.MailTo = " + Request.QueryString["prmCompanyNo"] + " ";
whereConcatenator = "AND ";
}
statement += " order by a.EmployeeName ";
SqlCommand cmd = new SqlCommand(statement, con);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);


if (dt.Rows.Count > 0)
{
TableLogOnInfo crTableLogOnInfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
CrystalDecisions.CrystalReports.Engine.Database crDatabase;
CrystalDecisions.CrystalReports.Engine.Tables crTables;
ReportDocument doc = new ReportDocument();
doc.Load(Server.MapPath("CrystalReport.rpt"));
var connectionInfo = new ConnectionInfo();
connectionInfo.ServerName = "ccc.com";
connectionInfo.DatabaseName = "xxx";
connectionInfo.Password = "ssss";

connectionInfo.UserID = "ttt";
connectionInfo.Type = ConnectionInfoType.SQL;
connectionInfo.IntegratedSecurity = true;


for (int i = 0; i < CrystalReportViewer1.LogOnInfo.Count; i++)
{
CrystalReportViewer1.LogOnInfo[i].ConnectionInfo = connectionInfo;
}

doc.SetDataSource(dt);
CrystalReportViewer1.ReportSource = doc;
