MVC Razor passing Model from View to Controller
Question
My Controller which calls the View:
public ActionResult Excel()
{
myClass arg = new myClass(string arg1, object arg2);
return View(arg);
}
My View:
@model myClass
@using (Html.BeginForm("createXML", "Excel", new { arg = Model }))
{ { @Html.ValidationSummary(true)
<div class="container-full" style="background-color:aliceblue">

}
Controller Function which should be called:
public ActionResult createXML(myClass arg)
{
//Code here...
return View("~/Views/Excel/Excel.cshtml");
}
My Problem is that "arg" is passed as null to createXML. I can't figure out why. One has to say that I am normally a WPF/WinForms Programmer.
UPDATE
I updated my code a bit, to make it clearer maybe.
UPDATE 2
I found out a part of the problem. My Object has only one constructor, where i need some paramateres. This generates somehow an error. I created a constructor without any parameter and it works, but it somehow creates a new object when I start my form and does not use the object i passed on to the view.

change view like this
@using (Html.BeginForm("createXML", "Excel", FormMethod.Post))
and
add this above createxml
[HttpPost]
UPDATE
I tried your codes and worked. Here is codes
HomeController codes. You can place this methods in your ExcelController
public ActionResult Excel()
{
myClass arg = new myClass();
arg.p = 5;
return View(arg);
}
[HttpPost]
public ActionResult createXML(myClass arg)
{
int a = arg.p;
return View();
}
Home/Excel.cshtml codes
@model Identity.Controllers.myClass
@{
Layout = null;
}
@using (Html.BeginForm("createXML", "Home", FormMethod.Post))
{ @Html.ValidationSummary(true)
<div class="container-full" style="background-color:aliceblue">
<h3 class="= container">Einstellungen:</h3>
<div class="container">
@Html.TextBoxFor(x => x.p)
<input type="submit" value="Submit" />
</div>
</div>
}

You are using wrong overload.
You can use this overload. BeginForm( this HtmlHelper htmlHelper, string actionName, string controllerName, Object routeValues, FormMethod method, Object htmlAttributes )
@Html.BeginForm("createXML", "Excel", new { arg = Model },FormMethod.Post,null)
or remove the argument and use hidden field within the form:
@using(Html.BeginForm("createXML", "Excel",FormMethod.Post))
{
.....
@Html.Hidden("arg", Model)
}
