Html rendering order for asp mvc - asp.net

How come my form loads like this?
Here is my code :
#using MvcApplication6.Models;
#model List<Employee>
#{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
Create Entry
</p>
<p>#Html.ActionLink("Check departments", "Index", "Department")</p>
<p>Check summary</p>
<table border="1">
<tr>
<th>
#Html.DisplayNameFor(model => model[0].id)
</th>
<th>
#Html.LabelFor(model => model[0].firstname)
</th>
<th>
#Html.LabelFor(model => model[0].lastname)
</th>
<th>
#Html.DisplayNameFor(model => model[0].gender)
</th>
<th>
#Html.DisplayNameFor(model => model[0].department)
</th>
<th>Action</th>
</tr>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
foreach (Employee mod in Model)
{
<tr>
<td>
<input type="hidden" value="#mod.id" name="id" id="id" />
#Html.DisplayFor(modelItem => mod.id)
</td>
<td>
#Html.DisplayFor(modelItem => mod.firstname)
</td>
<td>
#Html.DisplayFor(modelItem => mod.lastname)
</td>
<td>
#Html.DisplayFor(modelItem => mod.gender)
</td>
<td>
#Html.DisplayFor(modelItem => mod.department)
</td>
<td>
<button onclick="location.href='#Url.Action("Edit", new { id = mod.id })';return false;">Edit</button>
#Html.CheckBoxFor(modelItem => mod.selected)
</td>
</tr>
}
<br />
<input type="submit" value="submit" />
}
</table>
Here are my concerns:
Notice that i put my submit button after the foreach loop but how come it was rendered first before the actual boxes?
I've been trying to put it on the bottom but i am having some problems.
What's the ordering for render?

How to call drop down list by ajax call request when selected value changed?

I work on web app mvc .NET framework I face issue i can't call function GetSelectedDropDownChanged when drop down selected changed .
I put break point to function GetSelectedDropDownChanged on controller WorkforceRequests
but it not hit or catched so what is issue
so what I try is :
<th>
<select class="form-control" id="statusselect" name="statusselectName">
<option value="1">Pending Request</option>
<option value="2">All requests </option>
</select>
</th>
when select from drop down I expect to call it ajax request call to function WorkforceRequests controller WorkforceRequests :
<script>
$(function () {
$(document)
.on('change', '#statusselect', function () {
var valueofDropDown = $(this).val();
var url = '/WorkforceRequests/GetSelectedDropDownChanged';
var dataToSend = { selectedValue: valueofDropDown }
$.ajax({
url: url,
data: dataToSend,
type: 'GET',
success: function (dataReceived) {
//update control on View
var receivedValue = dataReceived.myResult;
$('YourControlIDToUpdate').val(receivedValue);
}
})
});
};
</script>
function i call from ajax request as below :
public class WorkforceRequestsController : Controller
{
[HttpGet]
public JsonResult GetSelectedDropDownChanged(string selectedValue)
{
List<WorkforceRequest> workforceRequest = new List<WorkforceRequest>();
if (selectedValue == "1")
{
workforceRequest = Workforce.GetPendingOnPalnningSection();
}
else
workforceRequest = Workforce.GetAllRequestsData();
return Json(new { myResult = workforceRequest }, JsonRequestBehavior.AllowGet);
}
}
data will returned as list from ajax call from function GetSelectedDropDownChanged ON table id dtbl
<table id="dtbl" class="table table-bordered table-hover table-striped">

<td>
#Html.DisplayFor(modelItem => item.Section)

}
</tbody>
</table>
Last Updated
I change my code inside view.cshtml to :
#model IEnumerable<HR.WorkforceRequisition.Models.WorkforceRequest>
#{
ViewBag.Title = "Pending Requests";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Pending Requests</h2>
<hr />
#if (!string.IsNullOrWhiteSpace(ViewBag.msg))

ASP.NET MVC Update fields of data Table at once

I have this view and I need to update the table Task upon the chosen values at Value Column View: EstimateValue. The view accepts #model IEnumerable then iterate the list of tasks and display them in Table.
The View
#model IEnumerable<Task>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<table class="table table-striped table-hover table-bordered">
<thead>
<tr class="info">
<th>
#Html.DisplayNameFor(model => model.Name)
</th>
<th>
#Html.DisplayNameFor(model => model.Description)
</th>
<th>
#Html.DisplayNameFor(model => model.Value)
</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
#Html.HiddenFor(modelItem => item.ID)
<td>
#Html.DisplayFor(modelItem => item.Name)
</td>
<td>
#Html.DisplayFor(modelItem => item.Description)
</td>
<td>
#Html.EditorFor(modelItem => item.Value, new { #class = "form-control" })
#Html.ValidationMessageFor(modelItem => item.Value, "", new { #class = "text-danger" })
</td>
</tr>
}
</tbody>
</table>
<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>
}
The Controller has the post method EstimateValue
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult EstimateValue(IEnumerable<Task> TaskList)
{
if (ModelState.IsValid)
{
foreach (var task in TaskList)
{
db.Entry(task).State = EntityState.Modified;
db.SaveChanges();
}
return RedirectToAction("Index");
}
//1. Rebound List to view
var TaskList = db.Tasks.ToList();
//2, return model to view
return View(TaskList);
}
When running the application the TaskList is null and I could not update the table Task. I have used JSON to send the data from the view as an array but still the values of TaskList are null
Change your IEnumerable to List because IEnumerable does not allow indexing. And instead of #foreach loop, use #for loop. So your View should be like this:
#model List<Task>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
<div class="form-horizontal">
<hr />
#Html.ValidationSummary(true, "", new { #class = "text-danger" })
<table class="table table-striped table-hover table-bordered">
<thead>
<tr class="info">
<th>
#Html.DisplayNameFor(model => Model[0].Name)
</th>
<th>
#Html.DisplayNameFor(model => Model[0].Description)
</th>
<th>
#Html.DisplayNameFor(model => Model[0].Value)
</th>
</tr>
</thead>
<tbody>
#for(int i=0;i<Model.Count;i++)
{
<tr>
#Html.HiddenFor(modelItem => modelItem[i].ID)
<td>
#Html.DisplayFor(modelItem => modelItem[i].Name)
</td>
<td>
#Html.DisplayFor(modelItem => modelItem[i].Description)
</td>
<td>
#Html.EditorFor(modelItem => modelItem[i].Value, new { #class = "form-control" })
#Html.ValidationMessageFor(modelItem => modelItem[i].Value, "", new { #class = "text-danger" })
</td>
</tr>
}
</tbody>
</table>
<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>
}
Then change your Controller:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult EstimateValue(List<Task> TaskList)
{
if (ModelState.IsValid)
{
for(int i=0;i<TaskList.Count;i++)
{
db.Entry(TaskList[i]).State = EntityState.Modified;
db.SaveChanges();
}
return RedirectToAction("Index");
}
//1. Rebound List to view
var TaskList = db.Tasks.ToList();
//2, return model to view
return View(TaskList);
}

Bind images in razor view to <img src> that are in loop

Right now the only thing i want to know is how to bind the Image to the "img src" in razor view.I have searched the other questions but did not find the answer for images in loop.The current way written down does not work."~/Images/" is the folder where the uploaded images are.
#model List<propertyMgmt.Models.Property>
<div id="propertyList">
<label>Select properties to be Featured:</label><br />
<table class="table">
<tr>
<th>
#Html.Label("Property Description")
</th>
<th>
#Html.Label("Property Cost")
</th>
<th>
#Html.Label("Property Image")
</th>
<th>
#Html.Label("Featured??")
</th>
</tr>
#for (int i=0;i<Model.Count;i++)
{
<tr>
<td>
#Html.DisplayFor(m => m[i].PropertyDescription)
</td>
<td>
#Html.DisplayFor(m => m[i].PropertyCost)
</td>
<td>
<img src="~/Images/#(m=>m[i].PropertyImage)" />
</td>
<td>
#Html.CheckBoxFor(m => m[i].IsFeatured, new {
#onclick = "propertyCheckBoxSelect(this)" })
</td>
</tr>
}
</table>
</div>
You can use like this.
<img src="~/Images/#(Model[i].PropertyImage)" />

MVC Core 1.0 NullReferenceException: Object reference not set to an instance of an object

My code is trying to enumerate over a (currently empty) list of movies. When it gets to the ForEach loop it blows up with the stated error.
I would think it would just not iterate (moveNext()). How can I fix this behavior so that it will just display an empty list when the collection is blank
#using System.Collections.Generic
#using Microsoft.EntityFrameworkCore.Metadata.Internal
#using x.Models
#model IEnumerable<x.Models.Movie>
#{
ViewData["Title"] = "MovieView";
}
<h2>MovieView</h2>
<p>
<a asp-action="List">Movie List</a>
</p>
<table class="table">
<thead>
<tr>
<th>
#Html.DisplayNameFor(model => model.Title)
</th>
<th>
#Html.DisplayNameFor(model => model.Description)
</th>
<th>
#Html.DisplayNameFor(model => model.Genre)
</th>
<th>
#Html.DisplayNameFor(model => model.Year)
</th>
<th></th>
</tr>
</thead>
<tbody>
#foreach (Movie item in Model)
{
<tr>
<td>
#Html.DisplayFor(modelItem => item.Title)
</td>
<td>
#Html.DisplayFor(modelItem => item.Description)
</td>
<td>
#Html.DisplayFor(modelItem => item.Genre)
</td>
<td>
#Html.DisplayFor(modelItem => item.Year)
</td>
<td>
<a asp-action="Edit" asp-route-id="#item.Id">Edit</a> |
<a asp-action="Details" asp-route-id="#item.Id">Details</a> |
<a asp-action="Delete" asp-route-id="#item.Id">Delete</a>
</td>
</tr>
}
</tbody>
</table>
