To pass values from one action method to another use Tempdata. Other way is store information in session.

Thank you Chetan Ranpariya

Answer 3

TempData is used when you are redirecting from one controller action to another controller action. In your code there is no redirection happening. Both the Controller actions are returning views.

 

If I am correct, you want to store the PatientCode selected in Controller1 somewhere so that you can use that is Controller2.

 

To be able to do this I think you should use Session variable. You can store "PatiendCode" in Session from Controller1 and retreive it in Controller 2. 

 

//Write following in Controller1
Session["CurrentPatient"] = PatientCode;

//Write following in Controller2
string patCode = Session["CurrentPatient"].ToString();

 

Answer 4

This is my code.But it takes null value to the second contoller

Controller1: 

public ActionResult ExaminePatient(string PatientCode)

{

List<Models.ExaminePatient> itemList = new List<Models.ExaminePatient>();

ExaminePatient examine = new ExaminePatient();

ExamineVm vm = new ExamineVm();

ExamineLoadingValues drop = new ExamineLoadingValues();

vm.Status = drop.Statusload();

itemList = drop.Visitinfo(PatientCode);

ViewData["itemList"] = itemList;

if(PatientCode!=null)

{

patcode = PatientCode.ToString();

ViewBag.patcode = patcode;

TempData["patcode"] = patcode;

}

return View("ExaminePatient", vm);

}

 

Controller2:

public ActionResult TestSelection()

{

List<Models.TestOrdereds> itemList = new List<Models.TestOrdereds>();

TestOrderDbs test = new TestOrderDbs();

TestOrderViewmodel vm = new TestOrderViewmodel();

itemList = test.Testordervalues();

ViewData["itemList"] = itemList;

TempData["patcode"] = patcode;

return View("TestSelection", vm);

}
