Bind Html CheckBoxListFor And Get Checked Values In ASP.NET MVC Controller

Introduction

In this article we will learn how to bind Html CheckBoxListFor and get checked values in ASP.NET Html CheckBoxListFor and get checked values in ASP.NET MVC Controller. So lets start with step by step approach.

Create an MVC Application

Now let us start with a step by step approach from the creation of simple MVC application as in the following:

"Start", then "All Programs" and select "Microsoft Visual Studio 2015".
"File", then "New" and click "Project..." then select "ASP.NET Web Application Template" and provide the Project a name as you wish and click on OK .

Add Model class

Right click on model folder of created MVC application project and add class named CityModel.cs or as you wish.

addnewitem

Now write the following code into the CityModel.cs class:

CityModel.cs:

public class CityModel
{
//Value of checkbox
public int Value
{
get;
set;
}
//description of checkbox
public string Text
{
get;
set;
}
//whether the checkbox is selected or not
public bool IsChecked
{
get;
set;
}
}
public class CityList
{
//use CheckBoxModel class as list
public List < CityModel > Cities
{
get;
set;
}
}

Add Controller

Right click on Controllers folder of created MVC application and click add empty Controller named HomeController.cs as.

mvc controller empty

Now create the generic list and add the records instead of going to database, however you can bind html checkboxlistfor-and get checked values in ASP.NET generic list from database but for example we added hard coded records.

HomeController.cs

public class HomeController: Controller
{
// GET: Home
public ActionResult Index()
{
//Add Records into generic list
List < CityModel > obj = new List < CityModel > ()
{
new CityModel
{
Text = "Latur", Value = 1, IsChecked = false
},
new CityModel
{
Text = "Mumbai", Value = 2, IsChecked = true
},
new CityModel
{
Text = "Pune", Value = 2, IsChecked = false
},
new CityModel
{
Text = "Noida", Value = 2, IsChecked = false
},
};
CityList objBind = new CityList();
objobjBind.Cities = obj;
return View(objBind);
}
//Post and get checkbox checked records
[HttpPost]
public ActionResult Index(CityList Obj)
{
StringBuilder sb = new StringBuilder();
foreach(var item in Obj.Cities)
{
if(item.IsChecked)
{
//append each checked records into StringBuilder
sb.Append(item.Text + ",");
}
}
//store location into viewbag
ViewBag.Loc = "Your preferred work locations are " + sb.ToString();
//return location view to display checked records using viewbag
return View("Locations");
}
public ActionResult Locations()
{
return View();
}
}

Add View

Right click on Views folder of created MVC application project and add empty view named Index.cshtml as

Now open the Index.cshtml view and write the following code into the view:

@
model BindStronglyTypedCheckBox.Models.CityList@
{
ViewBag.Title = "www.compilemode.com";
}
< div class = "form-horizontal" >< h4 > Select Preferred work location < /h4> @
using(Html.BeginForm())
{
for(int i = 0; i < Model.Cities.Count; i++)
{@
Html.CheckBoxFor(m => Model.Cities[i].IsChecked)@ Model.Cities[i].Text@ Html.HiddenFor(m => Model.Cities[i].Value)@ Html.HiddenFor(m => Model.Cities[i].Text) < br / >
}
< div class = "col-md-offset-2 col-md-10" >< input type = "submit"
value = "Save"
class = "btn btn-default" / >< /div> @
ViewBag.Loc
}
< /div>

Now everything is ready, run the application then the check box list will look like the following screenshot:

compilemode

Now select Pune and Noida then the output will be as follows:

pune,noida

Now select Latur and Mumbai:

latur mumbai

From all the above examples we have learned how to get check box values in ASP.NET MVC Controller.

Note:

Do proper validation such as date input values when implementing.
Download the Zip file of the sample application for a better understanding.
In this example CheckBoxList bound using generic list however you can also bind html Checkboxlistfor and get checked values in ASP.NET using database.
