ASP.Net MVC: Partial view not rendering - asp.net-mvc

i am bit new in asp.net mvc. i am facing problem for very basic things that my Partial view not rendering. here is the details
i have a main page and one partial view
main page action look like
public ActionResult Index()
{
return View();
}
main index view look like
#model Testing.Models.Employee
#{
ViewBag.Title = "Home Page";
}
<div class="row">
</div>
<div class="row">
<div id="formsIndex">
#{
Html.Partial("_TestForm");
}
</div>
</div>
#section scripts {
<script src="~/Scripts/jquery.unobtrusive-ajax.min.js"></script>
}
here i am showing a partial view like this way Html.Partial("_TestForm"); but no UI comes for partial view.
partial view code look like
#model Testing.Models.Employee
#using (Ajax.BeginForm("Index", "Home", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "formsIndex" }))
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Name, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Name, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Name, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.City, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.City, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.City, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Address, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Address, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Address, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-primary" />
</div>
</div>
</div>
}
when i pass model to partial view this way Html.Partial("_TestForm", Model); then also no UI comes.
please tell me where i made the mistake ?

use in method return PartialView() and try this
#Html.Partial("_TestForm");

Using Html.Partial inside a #{ ... } block will just call the method and throw the result away.
You should call it outside of a #{ ... } block, prefixed with #, and remember to pass in the model:
<div id="formsIndex">
#Html.Partial("_TestForm", Model);
</div>

Render like this
#Html.Action("_Partialview", "controllerName")
also create action methode of partial view
public ActionResult _Partialview
{
Employee _objModel= new Employee ()
return PartialView(_objModel);
}

Model is invalid despite values are correct, strange behaviour [duplicate]

I cannot figure out why my view only passes back a NULL for a model to my controller.
This is for an Edit Post method. I checked other controllers with Edit Post methods that are structured the same way as this one and they work fine. It seems to be just this view and controller.
Here is my view:
#model Non_P21_Quote_System_v1._0.Models.gl_code
#{
ViewBag.Title = "Edit";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Edit</h2>
#if (TempData["Message"] != null)
{
<div style="color:green">
#TempData["Message"]
</div><br />
}
#if (ViewBag.error != null)
{
<div style="color:red">
<h3>#ViewBag.error</h3>
</div><br />
}
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>gl_code</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
#Html.HiddenFor(model => model.ID)
<div class="form-group">
#Html.LabelFor(model => model.GL_code, "GL Code", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.GL_code, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.GL_code, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.GL_description, "Gl Description", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.GL_description, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.GL_description, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.expense_type_ID, "Expense", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("expense_type_ID", null, htmlAttributes: new { #class = "form-control" })
#Html.ValidationMessageFor(model => model.expense_type_ID, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.eag, "Employee Account Group", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("eag", null, htmlAttributes: new { #class = "form-control" })
#Html.ValidationMessageFor(model => model.eag, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
#Html.ActionLink("Back to List", "gl_Index")
</div>
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
}
Here is my controller method:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Edit([Bind(Include = "ID,GL_code,GL_description,expense_type_ID,eag")] gl_code gl_code)
{
if (ModelState.IsValid)
{
db.Entry(gl_code).State = EntityState.Modified;
await db.SaveChangesAsync();
return RedirectToAction("gl_Index");
}
ViewBag.eag = new SelectList(db.employee_account_group, "ID", "eag_name");
ViewBag.expense_type_ID = new SelectList(db.expense_type, "ID", "type", gl_code.expense_type_ID);
return View(gl_code);
}
When I debug it, I see the model being passed in is of value NULL. I am seeing this on the controller side at the the parameters part of the Edit method.
Its null because your model contains a property named gl_code and you have also named the parameter for your model gl_code in the POST method.
Change the name of one or the other and the model will bind correctly.
What is happening internally is that the form submits a name/value pair for each successful form control, in your case gl_code=someValue. The DefaultModelBinder first initializes a new instance of your model. It then reads the form values and finds a match for the property in your model and sets it to someValue. But it also finds a match in the method parameters and tries set the value of the parameter to someValue, which fails (because you cannot do gl_code gl_code = "someValue";) and the model becomes null.
It appears you have a property on your view model called gl_code. In your controller, you also refer to the view model as gl_code.
Try changing this.
public async Task<ActionResult> Edit(gl_code gl_code)
To
public async Task<ActionResult> Edit(gl_code model)

defaulting value in MVC create view before http post

Hi I am trying to default a date with 'DateTime.Now' in a create view. And setting an 'Active' field to 'true'
The following code does that in the the following action in the controller:
// POST: RequestTypes/Create
// To protect from overposting attacks, please enable the specific properties you want to bind to, for
// more details see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Create([Bind(Include = "Id,RequestTypeDescription,LastUpdated,Active,Team")] RequestType requestType)
{
if (ModelState.IsValid)
{
db.RequestTypes.Add(requestType);
requestType.LastUpdated = System.DateTime.Now;
requestType.Active = true;
await db.SaveChangesAsync();
return RedirectToAction("Index");
}
ViewBag.Team = new SelectList(db.Teams, "Id", "TeamDescription", requestType.Team);
return View(requestType);
}
That is the httppost code which defaults when the save is made.
What I want to do is to default those fields so that they show when the create view first gets launched - with the following code in the following action:
// GET: RequestTypes/Create
public ActionResult Create()
{
ViewBag.Team = new SelectList(db.Teams, "Id", "TeamDescription");
ViewBag.LastUpdated = System.DateTime.Now;
return View();
}
My Create View code is the standard created by MVC scaffolding:
#model ManageHR5.Models.RequestType
#{
ViewBag.Title = "Create";
}
<h2>Create</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>RequestType</h4>
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.RequestTypeDescription, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.RequestTypeDescription, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.RequestTypeDescription, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.LastUpdated, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.LastUpdated, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.LastUpdated, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Active, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
<div class="checkbox">
#Html.EditorFor(model => model.Active)
#Html.ValidationMessageFor(model => model.Active, "", new { #class = "text-danger" })
</div>
</div>
</div>
<div class="form-group">
#Html.LabelFor(model => model.Team, "Team", htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.DropDownList("Team", null, htmlAttributes: new { #class = "form-control" })
#Html.ValidationMessageFor(model => model.Team, "", new { #class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Create" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
#Html.ActionLink("Back to List", "Index")
</div>
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")}
When I run the app, and launch the create page, the defaults don't show up when the create page is launched.
What am I not understanding?
(A newbie to MVC :( )
You set them in the model on the Get for display purposes
// GET: RequestTypes/Create
public ActionResult Create() {
ViewBag.Team = new SelectList(db.Teams, "Id", "TeamDescription");
var model = new RequestType();
model.LastUpdated = System.DateTime.Now;
model.Active = true;
return View(model);
}
But like indicated in the provided comment
You set them immediately before you save the object in the POST method

Passing form input from view to controller

I'm working with a standard razor view with form data. I want to pass the input form data to my controller after pressing the submit button. My view looks like this:
#model CareSource.ReleaseAssistant.Models.Prime.Team
#{
ViewBag.Title = "Create";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Create New Team</h2>
#using (Html.BeginForm())

#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<div class="form-group">
#Html.LabelFor(model => model.Abbreviation, htmlAttributes: new { #class = "control-label col-md-2" })
<div class="col-md-10">
#Html.EditorFor(model => model.Abbreviation, new { htmlAttributes = new { #class = "form-control" } })
#Html.ValidationMessageFor(model => model.Abbreviation, "", new { #class = "text-danger" })

The problem is that the information in the form is not being passed back to my controller to be handled by my action method. I'm trying create a new entry in my database using web api. My action method looks like this:
[HttpPost]
public ActionResult Create(FormCollection collection)
{
try
{
if (ModelState.IsValid)
{
HttpEndPointContext httpEndPoint = new HttpEndPointContext()
{
AuthenticationMethod = HttpAuthenticationMethods.None,
Ssl = false,
HttpMethod = HttpMethod.Post,
//Path = "localhost:32173/api/team/",
QueryStrings = null,
};
IProcessResult result = HttpConnectionManager.Current.SendMessage(httpEndPoint);
var response = result.ResponseData.ToString();
}
return RedirectToAction("Index");
}
catch
{
return View();
}
}
Most of the code in this project was generated using Codesmith Generator and uses the MicroORM called PetaPoco.
Since your form is strongly typed to an instance of Team and you are using that to generate the input form fields, you can use Team object as the parameter of your HttpPost method.
HttpPost]
public ActionResult Create(Team model)
{
if (ModelState.IsValid)
{
//access model.Properties
}
return View(model);
}
Do use Team model as parameter remove formCollection and try
Please update your View with the given code :
#using (Html.BeginForm("Create", "YourControllerName", FormMethod.Post, new { id = "form" }))
{
//Copy your current code as it is here.
}

After i modify my Model : Values of my form are = NULL [duplicate]

I cannot figure out why my view only passes back a NULL for a model to my controller.
This is for an Edit Post method. I checked other controllers with Edit Post methods that are structured the same way as this one and they work fine. It seems to be just this view and controller.
