When I Click the Save Button on the Edit.aspx it call the Edit() but the Model on the page isn’t pass to the parameter, it just null.
When I try to save the change, the Products model won’t pass to the edit(). I using a Strongly-Typed View How do I get it to pass the Type to the Edit(Products) method?
How's is that going to solve the problem? My issue is when I Click save button the data on in view won't save ,because when the Edit() method is call the model is not pass to the Edit() methods. It just null. I'm assuming that mvc does this for you automatically.
For some reason mine won't work

From your code, it can be just only AFTER you submit , make an error in the Edit action and return View WITHOUT a model.

Save change when click Save button on edit.aspx

When I Click the Save Button on the Edit.aspx it call the Edit() but the Model on the page isn’t pass to the parameter, it just null.
When I try to save the change, the Products model won’t pass to the edit(). I using a Strongly-Typed View How do I get it to pass the Type to the Edit(Products) method?
Here the code I have.
public ActionResult Edit(int id)
{
return View(GetProductID(id));
}
//
// POST: /Products/Edit/5
[HttpPost]
public ActionResult Edit(Products id)
{
try
{
// TODO: Add update logic here
MyProductsEntity be = new MyProductsEntity();
Products origProduct = GetProductID(id.ProductID);
be.Products.Attach(id);
be.ApplyOriginalValues("Products", origProduct);
be.SaveChanges();
return RedirectToAction("Index");
}
catch
{
return View();
}
Here the View.
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<ProductsMVC.Models.Products>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
Edit
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Edit</h2>
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%: Html.LabelFor(model => model.ProductID) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.ProductID) %>
<%: Html.ValidationMessageFor(model => model.ProductID) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.Description) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Description) %>
<%: Html.ValidationMessageFor(model => model.Description) %>
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
<% } %>
<div>
<%: Html.ActionLink("Back to List", "Index") %>
</div>
</asp:Content>

When I try the code I it return a edit.aspx with empty fields and the following code "Object reference not set to an instance of an object."
When I try to Change the Post Edit(int id) I get the ID value. If I try Edit(Products id) it null the object is not pass.
