Question

I’m new in MVC2, so sorry for stupid question. I looked for nice answer, but can’t find it. So my question is:

I have view:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<IEnumerable<MyProject.MyDB.MyProducts>>" %>
<%@ Import Namespace="MyProject.MyDB" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Content" runat="server">
    <% using (Html.BeginForm())
       {%>
    <table>        
        <%
            foreach (var item in Model)
            {%>
        <tr>
            <td>
                <%:item.name%>
            </td>
            <td>
                <%:String.Format("{0:g}", item.date)%>
            </td>
        </tr>
        <% } %>
    </table>
    <div>
        <%:Html.TextArea("MyTextArea")%>
    </div>    
    <p>
        <input type="submit" value="Send" />
    </p>
    <% } %>
</asp:Content>

My controller is:

[HttpGet]
public ActionResult ViewMyProducts(int id)
{
        List<MyProducts> myModel = GetMyProducts(id);
        return View(myModel);
    }

    [HttpPost]
    public ActionResult ViewMyProducts(/*???What should I put here???*/)
    {
        if(/*I want "MyTextArea" value here*/ == something && myModel/*from view*/.count==5}
        {
            //do something
        }
        return View(myModel);
    }

So, in HttpPost I need myModel from view and value of “MyTextArea” from view. How can I get them?? I’ll appreciate any help.

I would think that the following should work:

[HttpPost]
public ActionResult ViewMyProducts(string MyTextArea)

A helpful thing to do would be to explicitly call your Action in your Form – by changing this line:

<% using (Html.BeginForm())

to

<% using (Html.BeginForm("ViewMyProducts","ControllerName",HttpMethod.Post))

to ensure that the Submit action redirects it to the right Action.

As far as the model is concerned:

If you are just checking the Count – you could make a hidden field that returns the number of items in the “Model” like such:

<%: Html.Hidden("modelCount", Model.Count());

but if you want the entire Model – it would be need to be something like this:

<%: Html.Hidden("myModel", Model);

then you could further modify your Action to look something like this:

ViewMyProducts(string MyTextArea, int modelCount)
{
    //...
}

or

ViewMyProducts(string MyTextArea, IEnumerable<MyProject.MyDB.MyProducts> myModel)
{
    //...
}

Although you have access inside of the Controller to refresh the Model – so if you didn’t need to pass back the entire thing you could still repopulate your view with a fresh call.
