Code to Dynamically Bind Image To Asp.net MVC WebGrid

7/10/2014 - By Pranav Singh 0


In this article I will show you how you can bind image to a webgrid in an mvc application using c#.net. In this we will use to bind the image data to image control present in the mvc webgid. This article we can use in mvc3, mvc4, mvc5.

So for this article first we will create a new as mvc application. Now we will create table



After this we will add an entity file in our application, after adding .edmx file we will add the table into our entity file.



Now we will create a model file, and add the below code into this.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace MVCDemo.Models
{
    public class StudentDetails
    {    
        public List<StudentDetail> Studentmodel { get; set; }
    }
    public class StudentDetail
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Address { get; set; }
        public string Class { get; set; }
        public string Section { get; set; }
        public string StudentImg { get; set; }
    }
}

Now we will add controller in our application. In this controller add the below code.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MVCDemo.Models;

namespace MVCDemo.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /UserLogin/

        public ActionResult Index()
        {
            StudentDetails _objuserloginmodel = new StudentDetails();
            List<StudentDetail> _objStudent = new List<StudentDetail>();
            _objStudent = GetStudentList();
            _objuserloginmodel.Studentmodel = _objStudent;
            return View(_objuserloginmodel);
        }
        public List<StudentDetail> GetStudentList()
        {
            List<StudentDetail> objStudent = new List<StudentDetail>();
            /*Create instance of entity model*/
            NorthwindEntities objentity = new NorthwindEntities();
            /*Getting data from database for user validation*/
            var _objuserdetail = (from data in objentity.Students
                                  select data);
            foreach (var item in _objuserdetail)
            {
                objStudent.Add(new StudentDetail { Id = item.Id, Name = item.Name, Address = item.Address,StudentImg=item.StudentImg });
            }
            return objStudent;
        }
    }
}

Now we will create view of the controller and add the below code in the view.

@model MVCDemo.Models.StudentDetails
@{
    ViewBag.Title = "Code to Dynamicelly Bind Image To Asp.net MVC WebGrid";
}
<b>Dynamicelly Bind Image To a Asp.net MVC WebGrid</b>
<style type="text/css">
    table
    {
        font-family: verdana,arial,sans-serif;
        font-size: 11px;
        color: #333333;
        border-width: 1px;
        border-color: #666666;
        border-collapse: collapse;
    }
    table th
    {
        border-width: 1px;
        padding: 8px;
        border-style: solid;
        border-color: #666666;
        background-color: #dedede;
    }
    table td
    {
        border-width: 1px;
        padding: 8px;
        border-style: solid;
        border-color: #666666;
        background-color: #ffffff;
    }
</style>
@using (@Html.BeginForm("Index", "Home"))
{
    var grid = new WebGrid(Model.Studentmodel, canSort: false, canPage: true, rowsPerPage: 5);
    <div>
        @grid.GetHtml(columns:
            grid.Columns
            (
                grid.Column("ID", "Stud ID"),
                grid.Column(

                 format: (item) =>
                 {
                     return Html.Raw(string.Format("<text><img src=\"{0}\" alt=\"Image\" width='100px' height='100px'/></text>", Url.Content(@item.StudentImg)));
                 }
                ),
                grid.Column("Name", "Stud Name"),
                grid.Column("Class", "Class"),
                grid.Column("Section", "Section"),
                grid.Column("Address", "Address")

                ), mode: WebGridPagerModes.Numeric)
    </div>  
}

In above code we have added image in webgrid.  Now run the application to view the output.
