How To Shown Selected menu in MVC 4

This article explaining for how to create menu's in mvc and how to set selected menu shown .

First add this styles in your css style sheet

ul#menu
{
font-size: 1.3em;
font-weight: 600;
margin: 0 0 5px;
padding: 0;
text-align:left;
position:absolute;
}

ul#menu li

list-style: none;
margin-left: 22px;

for(Please style.css is mine .But you must provide your css file only)

<head>

<link href="~/Content/style.css" rel="stylesheet" />

</head>

<div style="width: 100%; padding-bottom: 20px; margin-left: -7%; margin-top: 14%">
<br />
<ul id="menu">
<li id="home">@Html.ActionLink("Home", "Index", "Home")</li>
<li id="About">@Html.ActionLink("Discussions", "About", "Home")</li>
<li id="Compliance">@Html.ActionLink("Compliance", "ManageCompliance", "Compliance")</li>
<li>@Html.ActionLink("Reports", "About", "Home")</li>
<li>@Html.ActionLink("Documents", "Contact", "Home")</li>
<li id="FinancialCompliance" >@Html.ActionLink("Compliance", "ViewFinancialCompliances", "FinancialCompliance")</li>
<li id="Team">@Html.ActionLink("Team", "Contact", "Home")</li>
<li id="Admin">@Html.ActionLink("Admin", "Admin", "Admin")
</li>
</ul>
</div>

Now the above menu is showing like when ordinary showing menu and shown hover menu

okay .that finished .

Now you want selecting menu is showing static .So put the below code in your header tag inside

<script type="text/javascript">

$(document).ready(function () {

var url = window.location.pathname;
var home = "Home/Index";
var About = "Home/About";
var Compliance = "Compliance/ManageCompliance";//Put your page url
var Admin = "Admin/Admin";
var EditCompliance = "Compliance/EditCompliance";//Put your page url
var AddCompliance = "Compliance/AddCompliance";//Put your page url
var Team = "/Home/Contact";
var AddSchool = "Admin/AddSchool";//Put your page url
var AddDistrict = "Admin/AddDistrict";//Put your page url
var EditSchool = "Admin/EditSchool";//Put your page url
var EditDistrict = "Admin/EditDistrict";//Put your page url
var ViewFinancialCompliance = "FinancialCompliance/ViewFinancialCompliances"//Put your page url
var AddFinancialCompliance = "FinancialCompliance/AddFinancialCompliance"//Put your page url

if (url.indexOf(home) > -1) {
$("#home").addClass("select");
$(".select a:hover").addClass("select").show();
}
else if (url.indexOf(ViewFinancialCompliance) > -1) {
$("#FinancialCompliance").addClass("select").show();
}
else if (url.indexOf(AddFinancialCompliance) > -1) {
$("#FinancialCompliance").addClass("select").show();
}
else if (url.indexOf(About) > -1) {
$("#About").addClass("select").show();
}
else if (url.indexOf(Compliance) > -1) {
$("#Compliance").addClass("select").show();
}
else if (url.indexOf(AddCompliance) > -1) {
$("#Compliance").addClass("select").show();
}
else if (url.indexOf(EditCompliance) > -1) {
$("#Compliance").addClass("select").show();
}
else if (url.indexOf(Admin) > -1) {
$("#Admin").addClass("select").show();
}
else if (url.indexOf(AddSchool) > -1) {
$("#Admin").addClass("select").show();
}
else if (url.indexOf(AddDistrict) > -1) {
$("#Admin").addClass("select").show();
}
else if (url.indexOf(EditSchool) > -1) {
$("#Admin").addClass("select").show();
}
else if (url.indexOf(EditDistrict) > -1) {
$("#Admin").addClass("select").show();
}
else if (url.indexOf(Team) > -1) {
$("#Team").addClass("select").show();
}
else {
$("#home").addClass("select").show();
}

});

Create dropdownList in MVC with EntityFrameWork

This article will give's for how to create dropdownlist in mvc with Entity Frame Work?and how to get the database table values then bind dropdownlist

Create one class file(model) and create one property for datatype is SelectList in the class file for look below way

public class RegisterModel
{
public SelectList SchoolList { get; set; }
public int ScoolId { get; set; }
}

This above model property is using for assign database return values then bind the property values in  dropdownlist . You can understand back

Next,Just call database table(My Table name is School) values in one method for

SchoolBriefcaseEntities datamodel = new SchoolBriefcaseEntities();// It is my Entity class object

public IList<School> LoadSchools()
{
return datamodel.Schools.ToList();
}

The above LoadScools method was return some SchoolId and SchoolName(Its both of my table column name's).

Then call the LoadSchool method for

public SelectList BindSchools()
{
IList<School> schools = LoadSchools();
return new SelectList(schools, "SchoolId", "SchoolName");
}

Then Just call that RegisterModel and assign the database return values to model class(SchoolList) property in inside of our Controller ActionResult  method for

[AllowAnonymous]
public ActionResult Register()
{
RegisterModel registerModel = new RegisterModel();// It is Modelclass
registerModel.SchoolList = BindSchools();// assign the database return values in model class(SchoolList) property
return View(registerModel);
}

Then, Right click inside of the controller action result method (Register) -->Click Add View-->click the checkbox for create strongly _type view -->Select your modelclass in below dropdown (Now we have RegisterModel class .So we choose RegisterModel in this dropdownlist)--> Click Add Button .

Now the View(razor ) is created . you can see this view page in your solution explorer .Its display like for

@model SchoolBreifcase.Models.RegisterModel
@{
ViewBag.Title = "Register";
}
<h2>
Register</h2>
@using (Html.BeginForm())
{
@Html.ValidationSummary(true)

<fieldset>
<legend>RegisterModel</legend>
<div class="editor-label">
@Html.LabelFor(model => model.ScoolName)
</div>
<div class="editor-field">
  @Html.DropDownListFor(m => m.ScoolId, Model.SchoolList, "Select")
@Html.ValidationMessageFor(model => model.ScoolName)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}

The above green line is called the RegisterModel class property(SchoolName). But we have already assigned some values in this property from database in controller . So now the dropdownlist is display our database values . you can get dropdown selected value in ScoolId property

If you have any doubt , then please comment or message me .
