How can i use Bootstrap Carousel As a list for db records?

i was searching a bit and i really need to know how to use the bootstrap 4 class Carousel As a list of some model data ?
i tried to manage in my own and i made something like this in the view :
#model IEnumerable<ElMatrodySite.Models.NewsData>
<link href="~/Content/Home.css" rel="stylesheet" />
#{
ViewBag.Title = "Home Page";
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<style>
/* Make the image fully responsive */
.carousel-inner img {
width: 100%;
height: 100%;
}
</style>
<div class="container">
<div style="width:100%;height:150px;padding-top:0px; direction:rtl;">
<div class="row">
<div class="col-xl-4">
<img src="~/photos/Logo.png" class="mx-auto d-block" style="height:250px;"/>
</div>
<div class="col-xl-8" style="text-shadow:0px 4px 10px #808080; color:#352c5e;">
<br />
#if (Request.IsAuthenticated)
{
ElMatrodySite.Models.ApplicationUser Apps = new ElMatrodySite.Models.ApplicationUser();
<h2 class="mx-auto d-block text-center" id="ccword">مرحبًا بك #Apps.Firstname في موقع أسرة المطرودي !</h2>
}
else
{
<h2 class="mx-auto d-block text-center" id="ccword">مرحبًا بكم في الموقع الرسمي الجديد لأسرة المطرودي !</h2>
}
</div>
</div>
</div>
</div>
<div class="row" style="direction:rtl;">
<div class="container">
<div class="col-xl-6" style="padding-top:150px;" id="xcard">
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
#{
int i = 0;
}
#foreach (var item in Model)
{
<li data-target="#myCarousel" data-slide-to="#i" class="#(i == 0 ? "active" : "")"></li>
i++;
}
</ol>
<div class="carousel-inner">
#{
i = 0;
}
#foreach (var item in Model)
{
<div class="item #(i == 0 ? "active" : "")">
<img src="~/NewsPhotos/#item.file" class="image img-responsive">
<div class="carousel-caption">
<h3>#item.ArticleTitle</h3>
</div>
</div>
i++;
}
</div>
<a class="left carousel-control" href="#myCarousel" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>
</div>
</div>
</div>
that's wrong because every item in the list needs an id in the data-slide-to
and also one of them have to be active but it's possible while working with foreach to get the list of data.
this is the code in the controller :
[HttpGet]
public ActionResult Index()
{
List<NewsData> slideList = new List<NewsData>();
using (MatrodyEntities db = new MatrodyEntities())
{
var type = new NewsData();
slideList = db.NewsData.Where(xx => xx.ArticleID == type.ArticleID).Take(5).ToList();
return View(from NewsData in db.NewsData.ToList() select NewsData);
}
}
As i'm taking the latest 5 items added to the database.
so i need a small tutorial to make a Carousel list with asp.net mvc without destroying the whole design.

As I understand, you want to get list of data from the database and want to use bootstrap Carousel. As i noticed in your action method, you are getting latest 5 records and not passing same to view, instead of this you are using
return View(from NewsData in db.NewsData.ToList() select NewsData);
You can use directly
return View(slideList);
And in your view you can use model list as below
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
#{
int i = 1;
}
#foreach (var item in Model)
{
<li data-target="#myCarousel" data-slide-to="#i" class="#(i == 1 ? "active" : "")"></li>
i++;
}
</ol>
<div class="carousel-inner">
#{
i = 1;
}
#foreach (var item in Model)
{
<div class="item #(i == 1 ? "active" : "")">
<img src="#item.ImagePath" class="image img-responsive">
<div class="carousel-caption">
<h3>#item.Title</h3>
</div>
</div>
i++;
}
</div>
<a class="left carousel-control" href="#myCarousel" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>

Bootstrap slider in ASP.NET MVC from SQL Server database

I tried to make Bootstrap carousel slider for news from SQL Server database
I want the slider to look like this: https://www.w3schools.com/bootstrap/bootstrap_carousel.asp
But the role said
The .active class needs to be added to one of the slides. Otherwise, the carousel will not be visible.
but I did not know how to use .active class to one of my news because it is foreach loop.
All of my news has been under each other also, the left and right controls not working
Here is a screenshot of news slider result now
The code now:
HomeController.cs
public ActionResult Index()
{
return View(db.News.ToList());
}
Index.cshtml
#model IEnumerable<Project.Models.News>
#{
ViewBag.Title = "Home Page";
Layout = "~/Views/Shared/_Layout.cshtml";
}
#Scripts.Render("~/bundles/bootstrap")
<!--Start slide code-->
<div class="container imgs">
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
#foreach (var item in Model)
{
<div class="carousel-inner">
<div class="item active"> //My mistake is here, how to make first news of class active?
<div class="item ">
#{ string imageBase64 = Convert.ToBase64String(item.newImg);
string imageSrc = string.Format("data:image/gif;base64,{0}", imageBase64);
<img src="#imageSrc" />
}
<div class="carousel-caption">
<h3>#item.newName</h3>
Read More
#*<button type="button" class="btn btn-default">Read More</button>*#
</div>
</div>
</div>
</div>
}
<!-- Left and right controls -->
<a class="left carousel-control" href="#myCarousel" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>
</div>
Any help?

To add class="active" to the first element in the list you can either:
#{int v = 0;}
#foreach (var item in Model)
{
<div class="carousel-inner">
<div class="item#(v == 0 ? " active" : "")">
#item.newName
</div>
</div>
v++;
}
Or:
#foreach (var item in Model.Select((value, i) => new { i, value }))
{
<div class="carousel-inner">
<div class="item#(item.i == 0 ? " active" : "")">
#item.value.newName
</div>
</div>
}

Bootstrap Modal Pop Up bind controls - Dropdownlist

I have an HTML table which loads data from the database. When I click on a row a modal pop fetches more content from the database with an option to edit a change on the selected row.
My predicament is how do I populate a drop-down list and select a value saved in the database?
It is easy to bind other controls i.e. Textarea, input boxes etc. My issue is with dropdown lists.
FYI I'm using ASP.NET Web Forms with C# and I fetch the data from the database using jQuery AJAX and a WebService.
Thanx in advance.
I have mixed the presentation with the logic.
I have updated the question here is the js:
$("body").delegate("a.view-link", "click", function (e) {
e.preventDefault();
var requestID = $(this).data("reqid");
$.ajax({
type: "POST",
url: "../helpdeskservice.asmx/GetModalContent",
data: "{'requestID':'" + requestID + "'}",
contentType: "application/json;
charset=utf-8",
dataType: "json",
success: function (response) {
$('#modalEditCall').html(response.d); //Bind
$('#requestConfirmed').modal('toggle') } });
$('#modalEditCall').modal('toggle')
});
The WebService Method
[WebMethod]
public string GetModalContent(string requestID)
{
try
{
return ViewExtensions.GetCallModal(requestID);
}
catch (Exception ex)
{
throw ex;
}
}
The C# Class I use to build the html
public static string GetCallModal(string requestID)
{
var usrRequestObject = new DBHelpDesk();
var categories = usrRequestObject.GetCategories();
var modalddlCategories = new StringBuilder(String.Empty);
modalddlCategories.Append(#"<select class='custom-select w-100' id='modalddlCategory' required>");
foreach (var category in categories)
{
modalddlCategories.AppendFormat(#"<option value='{0}'>{1}</option>",category.CategoryID,category.Description);
}
modalddlCategories.Append("</select>");
var sb = new StringBuilder(String.Empty);
var userRequest = DBHelpDesk.GetCallByID(requestID);
sb.AppendFormat(#"

navbar icons jumping down when the window get smaller

I use bootstrap.my navbar icons jumping down when the window get smaller.when it is too small the menu goes to 3line icon bar.
How I can set my icons to appear in one line in small window?
here is my navbar code,
<nav class="navbar navbar-inverse navbar-fixed-top ">
<div class="container-fluid">

<div class="collapse navbar-collapse" id="myNavbar">

</nav>
and here is my CSS:
.header-style{
padding-top:20px !important;
background-image:url(../images/icon.png);
background-size: 100% 100% !important;
padding-left:40px !important;
padding-right:40px !important;
}
.li-header-style{
color:#ffe766
}
.navbar-fixed-top .nav {
padding: 15px 0;
}
#media (max-width:767px) {
.navbar-brand {
padding: 0;
}
.navbar-brand img {
margin-top: 1px;
margin-left: 1px;
}
}
.navbar-nav li a {
height:80px;
}
.navbar-nav li a {
padding-top: 0;
padding-bottom:0;
}
.navbar .nav > li.dropdown.open.active > a:hover,
.navbar .nav > li.dropdown.open > a {
color: #ffe766 !important;
background-color: transparent !important;
border-color: #ffe766 !important;
}
#brand-image
{
height:100px;
}

The problem is the icons are taking up too much space for the designated break-point.
I would advise reading the bootstrap documentation more thoroughly (especially the grid system): http://getbootstrap.com/css/#grid-media-queries
To fix your problem you would need to increase the .navbar breakpoint. This is explained very well here: https://coderwall.com/p/wpjw4w/change-the-bootstrap-navbar-breakpoint.
You can also look at this previous answer to help you: Change bootstrap navbar collapse breakpoint without using LESS

Show bootstrap panel in a row inside foreach loop

Here is my code, what should I do to show 3 panels in a row. Is there any way to do this?
Its showing in the same row but the next panel starts slightly below the previous one I'll be really thankful to you for your help
#foreach (DEProperty.Web.Models.PlotsViewModelSearchResult c in Model)
{
<div class="col-md-4">
<div class="panel panel-info">
<div class="panel-heading text-center">
<h4>#c.PhaseText, #c.SectorText-#c.PlotAddress</h4>
</div>
<div class="panel-body text-center">
<p class="lead">
<img src="~/images/plot...image.jpg" />
</p>
</div>
<ul class="list-group list-group-flush text-center">
<li class="list-group-item" style="border:none">
#c.AreaText
</li>
<li class="list-group-item" style="border:none">
Facing Park
</li>
<li class="list-group-item text-center" style="border:none">

</li>
</ul>
<div class="panel-footer">
<a class="btn btn-lg btn-block btn-info">Detail View</a>

Just Add <div class="row"> like this:
<div class="row">
#foreach (DEProperty.Web.Models.PlotsViewModelSearchResult c in Model)
{
....
}
</div>
