this.PatientID = id;
this.MaxID = MaxId;
Print(MaxId);
}
private void Print(int id)
{
PatientPay = new RptPatientPaymentReport();
try
{
if (PatientPay != null)
{
PatientPay.SetParameterValue("MaxID", id);
CrpViewerPatientPayment.ReportSource = PatientPay; //At this Point i am getting that error
CrpViewerPatientPayment.Refresh();
