for (int i = 0; i < dsCustomers.Tables[0].Rows.Count; i++)

        {

            string path = Application.StartupPath.Substring(0, (Application.StartupPath.Length - 10)) + "\\Reports\\RecieptReport.rpt";

            report1.Load(path);

            DateTime dateTime = Convert.ToDateTime(dsCustomers.Tables[0].Rows[i]["ContractStartdate"]);

            string ContractStartdate = dateTime.ToString("dd/MM/yyyy");

            report1.SetParameterValue("TodayDate", System.DateTime.Now.Date.ToString("dd/MM/yyyy"));

            report1.SetParameterValue("DepositeAmount", dsCustomers.Tables[0].Rows[i]["DepositeAmount"].ToString());

            report1.SetParameterValue("ReceiptNo", dsCustomers.Tables[0].Rows[i]["CustomerId"].ToString());

            report1.SetParameterValue("CustomerName", dsCustomers.Tables[0].Rows[i]["CustomerNameArabic"].ToString());

            report1.SetParameterValue("AmountInWord", dsCustomers.Tables[0].Rows[i]["AmountInWord"].ToString());

            report1.SetParameterValue("ContactStartdate", ContractStartdate);

            report1.SetParameterValue("BuildingCode", dsCustomers.Tables[0].Rows[i]["BuildingCode"].ToString());

            report1.SetParameterValue("FlatNo", dsCustomers.Tables[0].Rows[i]["FlatNo"].ToString());

            crystalReportViewer1.ReportSource = report1;

For displaying multiple you don't need to use foor loop.

You need to set the DataSource to the ReportDocument and reportDocument to the ReportSource property of CrystalReportViewer.

Using below article i have created the example.

Basic Crystal Report Tutorial with example in Windows Forms (WinForms) Application using C# and VB.Net

Check this example. Now please take its reference and correct your code.

Database

For this example I have used of Northwind database that you can download using the link given below.
