Cannot implicitly convert type 'System.Web.Mvc.RedirectToRouteResult' to 'System.Web.Mvc.JsonResult'

asp.net-mvc, asp.net-mvc-2, c#, json, model-view-controller

Solution

You need to use base class ActionResult so that you can return View,JSON,Content or Partial View:

public ActionResult AddTruckExpensesTransactionChild(string totaldays, string amount)
   {
        string Mess = objActive.Save();
        if (Mess == "1")
              return Json(new { Url = Url.Action("GetTruckExpensesChild", new { id = "", sid = "" }) });

        return Json(Mess, JsonRequestBehavior.AllowGet);
   }

But if you are calling this action via ajax you have to redirect to that action via javascript because returning `RedirectToAction` will return the html in response of ajax but not a redirect.

So you need to return action url via json with some flag and check that if response has that flag, redirect to that url via jquery.

In Ajax call success check if its url:

success: function(result) {
          if(result.Url.length > 0)
{
        window.location.href=result.Url;
}

Problem

How can i Redirect To Action from JsonResult to ActionResult but i m getting error. my error is "Cannot implicitly convert type 'System.Web.Mvc.RedirectToRouteResult' to 'System.Web.Mvc.JsonResult'". My Code Json Result: ``` public JsonResult AddTruckExpensesTransactionChild(string totaldays, string amount) { string Mess = objActive.Save(); if (Mess == "1") { return RedirectToAction("GetTruckExpensesChild", new { id="", sid="" }); } return Json(Mess, JsonRequestBehavior.AllowGet); } ``` ActionResult: ``` public ActionResult GetTruckExpensesChild(string id, string sid) { TruckExpensesTransactionClass Transaction = new TruckExpensesTransactionClass(); if (sid != null) { Transaction.TransactionChild = objActive.ShowTransactionChild(id, sid); return View(Transaction); } else { return View(Transaction); } } ```
