ASP.NET MVC 2 - First submit button on site doesn't work - rest is fine!
Sorry for unclear title - I don't know how to describe that problem in one sentence. Code sample will make it clear.
First UP button do nothing when clicked. Rest works like it should!
Below my view:
<%@ Page Title="" Language="C#"
MasterPageFile="~/Views/Shared/Main.Master"
Inherits="System.Web.Mvc.ViewPage<GeekClick.ViewModels.HomeViewModel>" %>
<asp:Content ID="Content2" ContentPlaceHolderID="head" runat="server">
<title>Beta</title>
</asp:Content>
<asp:Content ID="Content1" ContentPlaceHolderID="MainPageLinks" runat="server">
<h2>Najlepsze linki w sieci</h2&开发者_开发技巧gt;
<div id="HomePageLinks">
<%foreach (var link in Model.Links) { %>
<a href="<%:link.LinkURL %>"><b><%:link.Description %></b></a><br />
<%: Html.ActionLink("details", "Index", "Link", new {id = link.LinkID}, null) %>
<% using (Html.BeginForm("UpVote", "Home", new { linkId = link.LinkID }, FormMethod.Post)) {%>
<input type="submit" value="UP" /> <% } %>
<%: link.Votes %>
<% using (Html.BeginForm("DownVote", "Home", new { linkId = link.LinkID }, FormMethod.Post)) {%>
<input type="submit" value="DOWN" /> <% } %>
<% } %>
</div>
</asp:Content>
Controller:
[HttpPost]
public RedirectToRouteResult UpVote(int linkId)
{
var updateLink = _geekDb.Link.Single(a => a.LinkID == linkId);
updateLink.Votes++;
_geekDb.SaveChanges();
return RedirectToAction("Index");
}
[HttpPost]
public RedirectToRouteResult DownVote(int linkId)
{
var updateLink = _geekDb.Link.Single(a => a.LinkID == linkId);
updateLink.Votes--;
_geekDb.SaveChanges();
return RedirectToAction("Index");
}
And finally generated html:

<html xmlns="http://www.w3.org/1999/xhtml">

<body>
<form method="post" action="./" id="form1">
<div class="aspNetHidden">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwULLTE1NDk5OTQxMTBkZLMRoMOmMkoaJsHIkFWLWjn7HFSzna1LBeMqvRiCxdDQ" />
</div>
<div id ="mainPage" >

<div id="HomePageLinks">
<a href="Some link"><b>Something </b></a><br />
<a href="/Link/Index/1">details</a>
<form action="/Home/UpVote?linkId=1" method="post">

<form action="/Home/DownVote?linkId=1" method="post">

<a href="somelink"><b>Somedesc </b></a><br />
<a href="/Link/Index/2">details</a>
<form action="/Home/UpVote?linkId=2" method="post">
<input type="submit" value="UP" /> </form>10
<form action="/Home/DownVote?linkId=2" method="post">
<input type="submit" value="DOWN" /> </form>
</div>
</div>
</form>
</body>
</html>
There shouldn't be viewstate, should be?
I can't see there any problem in code. Someone can?
Looks like somewhere (perhaps in your Main.Master) you have a <form runat="server" /> that's messing things up.
It makes sense why your first button does not work - notice <form method="post" action="./"> at the top of your output - it's clashing with your other form and posting to the wrong action.
