working Create PDF Report from database in ASP.Net using C# and VB.Net

Create PDF Report from database in ASP.Net using C# and VB.Net



 
HTML Markup
Below is the HTML markup where I have an ASP.Net DropDownList which I’ll fill with the records of the employees from the Employees table and a Button which when clicked will generate the PDF report for the selected Employee.
<asp:DropDownList ID="ddlEmployees" runat="server">
</asp:DropDownList>
<asp:Button ID="btnReport" runat="server" Text="Generate Report" OnClick = "GenerateReport" />
 
Namespaces
You will need to import the following namespaces
C#
using iTextSharp.text;
using iTextSharp.text.pdf;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
 
VB.Net
Imports iTextSharp.text
Imports iTextSharp.text.pdf
Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration
 
Database Connection String
I have set the following connection string in the Connection Strings section of the Web.Config file
<connectionStrings>
 <addname="constr"connectionString="Data Source=.\SQL2005;Initial Catalog=northwind;User id = sa;password=pass@123"/>
</connectionStrings>
 
 
Populating the Employees DropDownList
Below is the code to bind the Employees DropDownList in the Page Load event of the ASP.Net Web Page.
Note:GetData is a Generic function to execute SELECT queries and returns DataTable

C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindEmployeesDropDown();
    }
}
private void BindEmployeesDropDown()
{
    ddlEmployees.DataSource = GetData("SELECT EmployeeId, (FirstName + ' ' + LastName) Name FROM Employees");
    ddlEmployees.DataTextField = "Name";
    ddlEmployees.DataValueField = "EmployeeId";
    ddlEmployees.DataBind();
}
private DataTable GetData(string query)
{
    string conString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    SqlCommand cmd = new SqlCommand(query);
    using (SqlConnection con = new SqlConnection(conString))
    {
        using (SqlDataAdapter sda = new SqlDataAdapter())
        {
            cmd.Connection = con;
 
            sda.SelectCommand = cmd;
            using (DataTable dt = new DataTable())
            {
                sda.Fill(dt);
                return dt;
            }
        }
    }
}
 
VB.Net
Protected Sub Page_Load(sender As Object, e As EventArgsHandles Me.Load
    If Not IsPostBack Then
        BindEmployeesDropDown()
    End If
End Sub
Private Sub BindEmployeesDropDown()
    ddlEmployees.DataSource = GetData("SELECT EmployeeId, (FirstName + ' ' + LastName) Name FROM Employees")
    ddlEmployees.DataTextField = "Name"
    ddlEmployees.DataValueField = "EmployeeId"
    ddlEmployees.DataBind()
End Sub
Private Function GetData(query As StringAs DataTable
    Dim conString As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Dim cmd As New SqlCommand(query)
    Using con As New SqlConnection(conString)
        Using sda As New SqlDataAdapter()
            cmd.Connection = con
 
            sda.SelectCommand = cmd
            Using dt As New DataTable()
                sda.Fill(dt)
                Return dt
            End Using
        End Using
    End Using
End Function
 
 
Generation of PDF Report using iTextSharp
Below is the code to generate the PDF with Employee details from database.
First I have fetched the details of the Employee based on the Employee ID from the DropDownList. Then I have created the Header of the report with Logo and name of the company. Below that a Horizontal line is drawn which separates out the Header with the Body.
The Body of the report contains the Employee Details like his Photo, Name, Designation and other details.
To reduce the size of code I have created three generic methods.
C#
protected void GenerateReport(object sender, EventArgs e)
{
    DataRow dr = GetData("SELECT * FROM Employees where EmployeeId = " + ddlEmployees.SelectedItem.Value).Rows[0]; ;
    Document document = new Document(PageSize.A4, 88f, 88f, 10f, 10f);
    Font NormalFont = FontFactory.GetFont("Arial", 12, Font.NORMAL, Color.BLACK);
    using (System.IO.MemoryStream memoryStream = new System.IO.MemoryStream())
    {
        PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);

        PdfPCell cell = null;

        table.TotalWidth = 500f;
        table.LockedWidth = true;
        table.SetWidths(new float[] { 0.3f, 0.7f });
 
        //Company Logo
        cell = ImageCell("~/images/northwindlogo.gif", 30f, PdfPCell.ALIGN_CENTER);
        table.AddCell(cell);
 
        //Company Name and Address
        phrase = new Phrase();
        phrase.Add(new Chunk("Microsoft Northwind Traders Company\n\n"FontFactory.GetFont("Arial", 16,Font.BOLD, Color.RED)));
