Nowadays MVC is popular so I decided to write an article on it looking at its importance.

Create a new ASP.NET MVC Solution, then DropDownBinding as a name of solution.

Webapplication

Select Empty Template and also select View engine as Razor.

ASP.NET Empty website

Add New Controller in Controller Folder.

Add a View.

Add view

Way 1: Dropdown Binding in View -Inline

@Html.DropDownList("Techonolgie", new List < SelectListItem > ()
{
new SelectListItem()
{
Text = ".Net", Value = "0"
},
new SelectListItem()
{
Text = "Java", Value = "1"
},
new SelectListItem()
{
Text = "Javascript", Value = "2"
},
new SelectListItem()
{
Text = "Angular", Value = "3"
},
new SelectListItem()
{
Text = "WCF", Value = "4"
}
}, "-- Select --")

Binding in View

When we run the application the output should be like the following,

run the Application

Way 2: Dropdown Binding using View Bag

public ActionResult Index()
{
List < SelectListItem > listTechonolgies = new List < SelectListItem > ()
{
new SelectListItem()
{
Text = ".Net", Value = "0"
},
new SelectListItem()
{
Text = "Java", Value = "1"
},
new SelectListItem()
{
Text = "Javascript", Value = "2"
},
new SelectListItem()
{
Text = "Angular", Value = "3"
},
new SelectListItem()
{
Text = "WCF", Value = "4"
}
};
ViewBag.Techonolgie = listTechonolgies;
return View();
}

Dropdown Binding

In View,

View

select technology

Way 3: Using Model Class

Right lick on Model Folder Add, then TechnologiesModel.cs - Class

Class

Class

Add the following two classes,

public class TechnologiesList
{
public SelectList lstTechnologies
{
get;
set;
}
}
public class Technologie
{
public int ID
{
get;
set;
}
public string TechnologieName
{
get;
set;
}
}

Namespace

The Controller code should look like the following,

public ActionResult Index()
{
List < Technologie > list = new List < Technologie > ();
list.Add(new Technologie()
{
TechnologieName = ".Net", ID = 0
});
list.Add(new Technologie()
{
TechnologieName = "Javascript", ID = 2
});
list.Add(new Technologie()
{
TechnologieName = "Angular", ID = 3
});
list.Add(new Technologie()
{
TechnologieName = "WCF", ID = 4
});
TechnologiesList TList = new TechnologiesList();
TList.lstTechnologies = new SelectList(list, "ID", "TechnologieName", 2);
return View(TList);
}

Select list

@model DropDownBinding.Models.TechnologiesList
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
<label>
Select Technologie
</label>
@Html.DropDownList("Tech",Model.lstTechnologies,"--Select--")
</div>
</body>
</html>
