Hi I am developing an application in MVC3. and i am stuck at one place. Everytime when control goes to IIndex1
action its argument value has become 0. But it should be same as value in IIndex
action argument. I have used session, ViewBag, ViewData but my problem is remains. Please suggest me.
public ActionResult GetMDN(string msisdn)
{
number = msisdn.Substring(0, msisdn.IndexOf('$'));
if (number.ToLower() != "unknown" && number.Length == 12)
{
number = number.Remove(0, 2);
}
Session["msdresponse"] = number;
Session["moptr"] = msisdn.Substring(msisdn.LastIndexOf('$') + 1);
number = msisdn;
int sngid=int.Parse(ViewData["isongid"].ToString());
return RedirectToAction("IIndex1", new { iid = sngid });
}
public ActionResult IIndex(int id)
{
ViewBag.isongid = id;
ViewData["isongid"] = id;
Response.Redirect("http:XXXXXXXXXXXXXXXX");
return RedirectToAction("GetMDN");
}
public ActionResult IIndex1(int iid)
{
}
TempData is used to pass data from one HTTP request to next HTTP request. o In other words, TempData is used to pass data from one controller to another controller or action to another action. TempData is a property of BaseController class.
You can have two method with the same name (and in fact it's a good practice to do that for forms). There are two requirements to have similar named methods. The methods must have different parameters. This is dictated by the programming language and is basically method overloading.
There are a number of ways in which you can pass parameters to action methods in ASP.NET Core MVC. You can pass them via a URL, a query string, a request header, a request body, or even a form. This article talks about all of these ways, and illustrates them with code examples.
You can use TempData.You can pass every types of data between to action, whether they are in same controller or not. Your code should be something like it:
public ActionResult GetMDN(string msisdn)
{
int sngid=10;
TempData["ID"] = sngid;
return RedirectToAction("IIndex");
}
public ActionResult IIndex()
{
int id = Convert.ToInt32(TempData["ID"]);// id will be 10;
}
Use TempData instead of ViewData/ViewBag to store data that should persist after redirect. ViewData/ViewBag allow to pass value from controller to view.
