ViewBag.Title = "تایید مدیریت";
}

<script>
// var afishstudio={
// id:$('@Html.TextBoxFor(Model => Model.id)').val();
// name:$('@Html.TextBoxFor(Model => Model.name)').val(),
//family:$('@Html.TextBoxFor(Model => Model.family)').val(),
//date:$('@Html.TextBoxFor(Model => Model.date)').val(),
//time:$('@Html.TextBoxFor(Model => Model.time)').val() }
// $(document).ready(function () {
// $("submit").click(function () {
// $.ajax({
// type: "post",
// url: '@Url.Action("index2")',
// data: {
// id: $('@Html.TextBoxFor(Model => Model.id)').val();
// name: $('@Html.TextBoxFor(Model => Model.name)').val(),
// family: $('@Html.TextBoxFor(Model => Model.family)').val(),
// date: $('@Html.TextBoxFor(Model => Model.date)').val(),
// time: $('@Html.TextBoxFor(Model => Model.time)').val()
// }
// a

// ) })

<h2> ورود به صفحه تایید آفیش </h2>

============================================

my controller :

public ActionResult index4(string modiran_semat,formafish formafish,FormCollection collection)

{

var model = new formafish();
TempData["name"] = model.name;
TempData["family"] = model.family;
TempData["date"] = model.date;
TempData["time"] = model.time;
TempData["modiran_name"] = model.modiran_name;
TempData["modiran_semat"] = model.modiran_semat;
TryUpdateModel(model, collection);
TryUpdateModel(model, modiran_semat);

if (ModelState.IsValid)
{
db.formafish.Add(model);
db.SaveChanges();
return RedirectToAction("PassValue_Index4", "formafish");
}

return View();

}
public ActionResult PassValue_Index4()

{

// ViewBag.id_formafish = TempData["id_formafish"];

ViewBag.name = TempData["name"];

ViewBag.family = TempData["family"];

ViewBag.date = TempData["date"];

ViewBag.time = TempData["time"];

ViewBag.modiran_name = TempData["modiran_name"];

ViewBag.modiran_name = TempData["modiran_semat"];

return View();

}

=================================

my new view :

<div class="form-horizontal">
<div class="panel panel-body">
<div style="direction:rtl !important;margin:40px auto;width:70%">

<div class="form-group">

نام:

<div class="col-md-10">

@Html.TextBox("name", (string)ViewBag.name, new { @style = "width: 300px;" })

</div>

<div class="form-group">

فامیلی :

<div class="col-md-10">

@Html.TextBox("family", (string)ViewBag.family, new { @style = "width: 300px;" })

</div>

<div class="form-group">

تاریخ :

<div class="col-md-10">

@Html.TextBox("date", (Int32)ViewBag.date, new { @style = "width: 300px;" })

</div>

<div class="form-group">

مدت :

<div class="col-md-10">

@Html.TextBox("time", (Int32)ViewBag.time, new { @style = "width: 300px;" })

There's a lot of issues with the code shown. There's a View with two forms but the target actions are not posted; Index3 and Index5. The action that is posted, Index4, does not have a View. What's very confusing is the code snippets look like MVC but have ASP.NET Core tag helpers.

This post as well as your others are all related to understanding the basics. IMHO, your best course of action is taking the time to go through the tutorials on this site

https://www.asp.net/learn

Keep in mind this is an MVC forum. If you require ASP.NET Core support, post in the ASP,NET Core forum.

Hi aabedeni056,

aabedeni056

According to your code,some places are not clear.

You did not show the code of Index3 and Index5 action.

How did you operate?

Do you think it is not necessary to show these codes?

So I guess, are you just click this button?
```
@Html.ActionLink(" ثبت آفیش ", "../formafish/index4", null, new { @class = "btn btn-success" })
```
If so, the controller does not receive the parameters,because @Html.ActionLink did not pass parameters.

If you would like to pass :
```
@Html.ActionLink(
" ثبت آفیش ",                                     linkText
 "../Home2/PassValue_Index",                       actionName
new { modiran_semat = "111",key2=value2,... },     routeValues
new { @class = "btn btn-success"}                  htmlAttributes
)
```
But I still recommend that you submit data using a form. What you should want is to submit a lot of data instead of a few.

I think you could add some breakpoints on your code to check your parameters and return values.

And hope that you could follow the MVC tutorial system.

https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/implementing-basic-crud-functionality-with-the-entity-framework-in-asp-net-mvc-application

Otherwise, your programming will be very tired.

Best Regards.
