Calling PostMethod from HTML.Actionlink - asp.net-mvc

Question

Hi I am fairly new to MVC and facing a issue.
I have a View which lists all the countries having just 2 columns
I want column headers clickable and should sort on clicking on it
I have shown my Controller & view code below and I expect that when I click on the column header it should hit Index action method decorated with [HttpPost]
When I click the header link page just refreshes without hitting Action method I expect it to hit
Any help would be appreciated.
Here is my controller code
[HttpPost]
public ActionResult Index(string sortcolumn)
{
return View(SortedList(sortcolumn));
}
private List<Country> SortedList(string sortcol)
{
List<Country> sortedlist = new List<Country>();
switch (sortcol)
{
case "idCountry":
if ((SortOrder)ViewData["sortorder"] == SortOrder.Ascending)
{
sortedlist = db.Countries.OrderByDescending(c => c.idCountry).ToList<Country>();
ViewData["sortorder"] = SortOrder.Descending;
}
else
{
sortedlist = db.Countries.OrderBy(c => c.idCountry).ToList<Country>();
ViewData["sortorder"] = SortOrder.Ascending;
}
break;
case "Countryname":
if ((SortOrder)ViewData["sortorder"] == SortOrder.Ascending)
{
sortedlist = db.Countries.OrderByDescending(c => c.Countryname).ToList<Country>();
ViewData["sortorder"] = SortOrder.Descending;
}
else
{
sortedlist = db.Countries.OrderBy(c => c.Countryname).ToList<Country>();
ViewData["sortorder"] = SortOrder.Ascending;
}
break;
}
return sortedlist;
}
Here is my view
<%# Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<eduSmart.Data.Entities.Country>>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Index
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>
List of Countries</h2>
<p>
Manage list of countries on this page. You can choose your action creating, editing,
removing the country data.
</p>
<% using (Html.BeginForm("Index","Country")) { %>
Total Countries : <%: Model.Count() %>
<table>
<tr>
<th>
<%: Html.ActionLink("CountryID","Index",new { sortcolumn = "CountryID" }) %>
</th>
<th>
<%: Html.ActionLink("CountryName ", "Index", new { sortcolumn = "CountryName" })%>
</th>
<th>
</th>
</tr>
<% if (Model != null)
{ %>
<% foreach (var item in Model)
{ %>
<tr>
<td>
<%: item.idCountry%>
</td>
<td>
<%: item.Countryname%>
</td>
<td>
<%: Html.ActionLink("Edit", "Edit", new { id = item.idCountry })%>
|
<%: Html.ActionLink("Details", "Details", new { id = item.idCountry })%>
|
<%: Html.ActionLink("Delete", "Delete", new { id = item.idCountry })%>
</td>
</tr>
<% }
}%>
</table>
<%} %>
<p>
<%: Html.ActionLink("Create New", "Create") %>
</p>
</asp:Content>

You can't hit a post method with an Action link. One thing you could do, if all you're doing is sorting here, is change your post method to a get and change the name
Instead of
[HttpPost]
public ActionResult Index(string sortcolumn)
Have something like
public ActionResult Sort (string sortColumn)
And point your actionlink to Sort.
