May 02, 2010 03:59 PM|LINK

I am using asp.net mvc,

I have a problem that i can not resolve it, when i return a view() in form postback, Browser show savefile dialog.

I save file and open it, It contian all page html content.

I also try to set content type by set response.contenttype but there is no effect on result.

Firefox say content type is application/json,

post method like this simple code : public actionresult index(){ return view() }

Can you help me?

There is no "postback" in ASP.NET MVC; it's a different paradigm from WebForms.

Take a look at the written movie database tutorial;
do not just read it, actually do it.

You will see how it handles POST ... do not confuse POST with "Postback".

You can help others help you by showing more of your code.

Could you post your controller and view code? Are you using AJAX?

And if you throw an exception somewhere so that the code falls through and uses the return View("Error") at the bottom, does the save file dialog pop up? Are there partial views beign returned? Have you tried naming the methods differently? (since both are called LogOn). Have you tried decorating the normal LogOn method with [AcceptVerbs(HttpVerbs.Get)] and checked if that might make a difference?

Just spawning ideas to try since I'm not seeing anything out of the ordinary on first sight.

        {
            return View();
        }


        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Index(FormCollection FormData)
        {
            return View();
        }


    }
}

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/MainSite.Master" Inherits="System.Web.Mvc.ViewPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
	Index
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>Index</h2>
<form method="post">

Could you try naming the functions differently? Like Index() and IndexPost(). And use a return View("Index"); in the later. It's strange that your solution started malfuntioning in the middle of development. Did you make any significant changes or override certain standard MVC behaviour somewhere?

The only reason the Save File Dialog is shown is due to Content Type.

I think you have set Response.ContentType in some where in Http Module or global.asax.

just try this code,

Not Show Dialog

        Response.ContentType = "text/html";
        Response.Clear();
        Response.Write("A");
        Response.End();

Shows Dialog

        Response.ContentType = "application/octet-stream";
        Response.Clear();
        Response.Write("A");
        Response.End();
