Add New Row

Question

Dear Friends,

Here I have a grid which was filled only two column Item and subItem as dropdown and then other columns will come from database(SQL) as user has number of distributor Name as Dynamic Template Columns created in Grid and Then added text and textboxes ids created at runtime as the "dist" and number of distributor he has like "Dist1" , "Dist2" , "Dist3".

This create ok after that when I clicked on AddRow Button which is outside of the grid and I have created a loop for getting all dropdown as well as textboxes created inside grid but could not getting.

 

My think is that after filling of 10 record user will click on addrow to add new record.

Here I am not getting ID of textbox on the time of loop.

Please give me a good example how to solve this problem.

Thanks in advance

I'm not sure that it's a good idea to write a LINQ query which just changes the state of existing objects and then adds them to a List but, if you must do it, then I'd try this:

List<ServiceDetail> serviceDetails = ServiceDetails 

.Where(serviceItem =>

{

  serviceItem.Patient = Patients.Where(i => i.PatientId == serviceItem.PatientId).FirstorDefault();

  serviceItem.Registration = Registrations.Where(i => i.RegistrationId == serviceItem.RegistrationId).FirstorDefault();

  return true; // select everything regardless

})

.ToList();

Answer 5

Thanks for Response,

I have a Collection like ServiceDetails. It Contains 

Patient Object and Registration Object

ServiceDetail serviceDetail=new ServiceDetail ();
serviceDetail.Patient=new Patient();
serviceDetail.Registration=new Registration();

ServiceDetails(serviceDetail);

Above Is my Objct Formation.

In this case I have Two Other Collections Like 'Patients' and 'Registrations'

For above Object formation I wrote like below
 
List<ServiceDetail> serviceDetails=new List<ServiceDetail>();
foreach(ServiceDetail serviceItem in ServiceDetails)
{
          //Bind Patient Object
        serviceItem.Patient=Patients.where(i=>i.patientid==serviceItem.patientid)
                                        .firstorDefault();
          //Bind Registration Object
        serviceItem.Registration=Registrations.where(i=>i.registrationId==serviceItem.registrationid)
                                        .firstorDefault();
        serviceDetails.add(serviceItem);

}

  ServiceDetails=new List<ServiceDetail>(serviceDetails); 
  
 For above collection formation I used one foreach. My query is I don,t used even one foreach also to make a Collection, instead of foreach I want to use Lamda expression or Linq Query .

Could you give any Idea on this Query Please?

It's impossible for any one to answer this question unless you tell us what the relationship is between the Patient, Registration and ServiceDetails classes.

Jean's made a good guess that the first two inherit from the third but another possibility is that a ServiceDetails object is somehow constructed from instances of the other two classes.

Hello Murali,

I can provide a solution in which the above typed lists are casted to object.
(I believe the classes Registration and Patient are deriving from ServiceDetails)

            List<Registration> l1 = new List<Registration>();

            List<Patient> l2 = new List<Patient>();

            List<ServiceDetails> l3 = new List<ServiceDetails>();

            l3.AddRange(l1.Cast<ServiceDetails>());

            l3.AddRange(l2.Cast<ServiceDetails>());

The above code is in Lambda..

If the classes are not having base as ServiceDetail, you may declare an implicit operator overloading like..
(but not sure it will fit the above code)

 public class Patient

    {

        public static implicit operator ServiceDetail(Patient p)

        {

            return new ServiceDetail();

        }

    }
