ASP.NET MVC: Values are null when they reach the Controller - asp.net-mvc

Question

So I have the following Controller:
[HttpPost]
public ActionResult CreateSupport(CreateSupport model)
{
if (ModelState.IsValid && (model.Description != null))
{
model.CreatedById = UserId;
model.ModifiedById = UserId;
}
return View(model);
}
I have the following view:
#using (Html.BeginForm("CreateSupport", "Support", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend></legend>
<div class="editor-label">
#Html.LabelFor(model => model.Subject, new Dictionary<string, object>() { { "class", "req" } })
</div>
<div class="editor-field">
#Html.TextBoxFor(m => m.Subject)
#Html.ValidationMessageFor(model => model.Subject)
</div>
<div class="support-form-left">
<div class="editor-label">
#Html.LabelFor(model => model.BrowserInfo, new Dictionary<string, object>() { { "class", "req" } })
</div>
<div class="editor-field">
#Html.TextBoxFor(m => m.BrowserInfo)
#Html.ValidationMessageFor(model => model.BrowserInfo)
</div>
</div>
<div class="support-form-right">
<div class="editor-label">
#Html.LabelFor(model => model.DatabaseVersion, new Dictionary<string, object>() { { "class", "req" } })
</div>
<div class="editor-field">
#Html.TextBoxFor(m => m.DatabaseVersion)
#Html.ValidationMessageFor(model => model.DatabaseVersion)
</div>
</div>
<div class="clearFloat"></div>
<div class="editor-label">
#Html.LabelFor(model => model.Description, new Dictionary<string, object>() { { "class", "req" } })
</div>
<div class="editor-field">
#Html.EditorFor(model => model.Description)
#Html.ValidationMessageFor(model => model.Description)
</div>
<div class="actionButtons">
<button id="btnCancel" class="myButtonCancel">Cancel</button>
<input type="submit" value="Submit" class="myButton" />
</div>
#if (ViewBag.SuccessMessage != null)
{
<div>
<label style="color: red;">#ViewBag.SuccessMessage</label>
</div>
}
</fieldset>
}
Here's the Model:
public class CreateSupport : SupportTicket
{
public CreateSupport()
{
ProductList = new List<Product>();
ProductVersionsList = new List<ProductVersion>();
EnviromentList = new List<InstallationEnvironment>();
content = new Content();
}
[Required]
[UIHint("tinymce_jquery_full"), AllowHtml]
public string Description { get; set; }
[Required]
[DisplayName("Browser version Info.")]
public string BrowserInfo { get; set; }
[Required]
[DisplayName("Database Version")]
public string DatabaseVersion { get; set; }
public Content content { get; set; }
}
The problem is that the values that reach the Controller are NULL even if you enter some value in them.

Answer 1

You should check your browser's developer tools to see if the form is properly posting its values. If it isn't, you should do two things:
A) Disabled javascript to see if there is a script that is interfering with the POST (typically either by disabling or clearing fields)
B) Ensuring your markup is valid using the W3C markup validation service

Answer 2

For input fields use
#Html.EditorFor(x => x.Subject)
For display fields use
#Html.DisplayFor(x => x.Subject)
