MVC form load calling both controller method and its overload method instead of calling on click methos ?...
0
i am saving data on click button but view when load first time entering to overload method ?
my view code is like,
@using (Html.BeginForm("ManageQuestion", "Questions", FormMethod.Post))
{
<input type="submit" value="Save" />
}
and my Controller is like,
public ActionResult ManageQuestion()
{
//List<SelectListItem> QuestionType = Survey();
//return View(QuestionType);
return View();
}
[HttpPost]
public ActionResult ManageQuestion(Question Objquest)
{
if (ModelState.IsValid)
{
SurveyAppEntities ObjEntity = new SurveyAppEntities();
string strDDLValue = Request.Form["DDlDemo"].ToString();
Objquest.QuestionType = strDDLValue;
ObjEntity.Questions.Add(Objquest);
ObjEntity.SaveChanges();
ViewData["error"] = "Question Saved successfully";
if (Objquest.ID > 0)
{
// ViewBag.Success = "Inserted";
}
ModelState.Clear();
}
return View();
}
}
I am thinking that it must call overload ManageQuestion method on button click but when view load first time it is entering in overload methos resulting in error.
I got one example from net having same scenario but overload method is not calling there on first form load ?
Hopes for your suggestion
Thanks

don't make another method, i mean mark the existing method with the attribute [HttpGet] so you will have two methods named "ManageQuestion" one will be used to render the view initially and the other to post the data and then rerender the view
