How to export PDF in ASP.NET MVC

Create the Project in ASP .NET MVC and connect database and fetch the record using Dapper ORM and export the data into PDF.

  • Create a ASP.NET MVC application using Visual Studio.
  • We select as Empty project with targeting to ASP.NET MVC.
  • Create a Controller inside the controllers folder, let’s name as “EmployeeController.cs”
  • The Employee Db contains a employee table that holds the employee information. The script are find below;

Database Script

CREATE TABLE [dbo].[EmployeeDetails](
	[EmpID] [int] NOT NULL,
	[EmpName] [varchar](50) NULL,
	[Mobile] [varchar](10) NULL,
	[PresentAddress] [varchar](100) NULL,
	[Area] [varchar](50) NULL,
	[City] [varchar](50) NULL,
	[Country] [varchar](50) NULL,
	[Qualification] [varchar](50) NULL,
	[Email] [varchar](50) NULL,
 CONSTRAINT [PK_EmployeeDetails] PRIMARY KEY CLUSTERED 
(
	[EmpID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

Employee.cs

Add a employee property class in Models folder.

public class Employee
    {
        public int EmpID { get; set; }
        public string EmpName { get; set; }
        public string Mobile { get; set; }
        public string PresentAddress { get; set; }
        public string Area { get; set; }
        public string City { get; set; }
        public string Country { get; set; }
        public string Qualification { get; set; }
        public string Email { get; set; }
    }

Connection string

Declare the connection string in Web.config like below;

 <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=corespider;Initial Catalog=EmployeeDb;Persist Security Info=True;User ID=sa;password=**********;Pooling=false;Connect Timeout=300000" providerName="System.Data.SqlClient" />
  </connectionStrings>

To connect with database and fetch the record, her ewe use Dapper ORM.

What is Dapper ?

Dapper is an object-relational mapping product for the Microsoft .NET platform: it provides a framework for mapping an object-oriented domain model to a traditional relational database. Its purpose is to relieve the developer from a significant portion of relational data persistence-related programming tasks.

Add Dapper package in Nuget

EmployeeRepository.cs

Add another class in Models folder to retrieve the employee information from database.

public class EmployeeRepository
    {
        public IDbConnection connection
        {
            get
            {
                return new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
            }
        }
        public async Task<object> GetEmployeeList()
        {
            object result = null;
            try
            {
                using (IDbConnection con = connection)
                {
                    string Query = "SELECT EmpID, EmpName, Mobile, PresentAddress, Area, City, Country, Qualification, Email" +
                                    " from EmployeeDetails";
                    con.Open();
                    DynamicParameters param = new DynamicParameters();
                    result = await con.QueryAsync<Employee>(Query, param, commandType: CommandType.Text);
                }
                return result;
            }
            catch (Exception ex)
            {
                throw ex;
            }

            return result;
        }

    }

Code Explanation

  • Here We create the IDbConnection that hold the connection string information.
  • Using Dapper ORM fetch the employee tables.
  • In real-time application you may use Stored procedure instead of text.
  • Dapper ORM directly return the list of employee.

EmployeeController.cs

EmployeeRepository _emprepo = new EmployeeRepository();
        // GET: Customer
        public async Task<ActionResult> Index()
        {
            List<Employee> _empList =await _emprepo.GetEmployeeList() as List<Employee>;
            return View(_empList);
        }

Code Explanation

  • Here we create object of the employee repository class.
  • In the Index() we fetch the employee list and return to the view.

Index.cshtml

@model IEnumerable<ExportPDFMVC.Models.Employee>

@{
    ViewBag.Title = "Index";
}
@using (Html.BeginForm("Export", "Employee", FormMethod.Post))
{
    <div class="container" style="margin-top:10px;">
        <input type="submit" value="Export to PDF" class="btn btn-primary" />
    </div>
    <table class="table">
        <tr>
            <th>
                @Html.DisplayNameFor(model => model.EmpID)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.EmpName)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Mobile)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.PresentAddress)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Area)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.City)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Country)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Qualification)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Email)
            </th>
            <th></th>
        </tr>

        @foreach (var item in Model)
        {
            <tr>
                <td>
                    @Html.DisplayFor(modelItem => item.EmpID)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.EmpName)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.Mobile)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.PresentAddress)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.Area)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.City)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.Country)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.Qualification)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.Email)
                </td>
              
            </tr>
        }
       </table>
}

Code Explanation

  • Here we use scaffold technique to create list of employees.
  • Added a button to Export the data into PDF.
  • Export is the action method and Employee is the Controller.

Export Action method to convert PDF

[HttpPost]
        public async Task<ActionResult> Export()
        {
            List<Employee> _empList =await _emprepo.GetEmployeeList() as List<Employee>;
            using (StringWriter sw = new StringWriter())
            {
                using (HtmlTextWriter hw = new HtmlTextWriter(sw))
                {
                    //To Export all pages
                    GridView gridview = new GridView();
                    gridview.DataSource = _empList;
                    gridview.DataBind();

                    gridview.RenderControl(hw);
                    StringReader sr = new StringReader(sw.ToString());
                    Document pdfDoc = new Document(PageSize.A2, 10f, 10f, 10f, 0f);
                    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
                    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
                    pdfDoc.Open();
                    htmlparser.Parse(sr);
                    pdfDoc.Close();
                    Response.ContentType = "application/pdf";
                    Response.AddHeader("content-disposition", "attachment;filename=Export.pdf");
                    Response.Cache.SetCacheability(HttpCacheability.NoCache);
                    Response.Write(pdfDoc);
                    Response.End();
                }
            
                return View();
            }
        }

Code Explanation

  • In the export Post method we fetch the employee information.
  • To export data into PDF we use Gridview controls that are in System.Web.UI.WebControls namespace.
  • In Gridview controls hold the employee list.
  • In the string writer and string Reader st the PDF using HTMLWorker.
  • Response content type as PDF and finally append the PDFdoc that export into PDF.

Run the application and see the output

export-excel-pdf

After click the export button it convert the above data into PDF like below;
