Model Binding using ASP.NET MVC, getting datainput to the controller - asp.net-mvc

Question

Pretty Basic one here guys.
I have a View which holds 2 textfields for input and a submit button
<%using (Html.BeginForm("DateRetrival", "Home", FormMethod.Post)){ %>
<%=Html.TextBox("sday")%>
<%=Html.TextBox("eday")%>
<input type="submit" value="ok" id="run"/>
<% }%>
the following controller action which I want to bind the data input is as follows
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult DateRetrival()
{
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DateRetrival(string submit)
{
return null;
}
When I debug this and look in the action methods parameter, the value is null. When I've entered values in both textboxes and and clicked the submit method.

Answer 1

You probably want to do something like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DateRetrival(string sday, string eday)
{
return null;
}
Ideally, though you probably want to be passing a model to your controllers:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DateRetrival(DateModel dates)
{
var date1 = dates.sday;
var date2 = dates.eday;
return null;
}

Answer 2

Add parameters to catch each input field value.
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DateRetrival(string sday, string eday)
{
return null;
}

Answer 3

Try:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult DateRetrival(string sday, string eday, string submit)
{
return null;
}
and if you want sumbit button value
<input type="submit" value="ok" id="run" name="submit"/>
If you want to have value posted, name attribute has to be set. Html.TextBox automatically sets name from parameter.
