Convert HTML to PDF with CSS using iText7 in ASP.Net

Hi dharmendr,

I later tried this code and it is working, But the gridview width is not 100% in PDF and height is not the same as the one in the HTML

CODE:

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.tool.xml;
using iTextSharp.tool.xml.html;
using iTextSharp.tool.xml.parser;
using iTextSharp.tool.xml.pipeline.css;
using iTextSharp.tool.xml.pipeline.end;
using iTextSharp.tool.xml.pipeline.html;
using System.Text;
using iText.Html2pdf;


     protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[4] { new DataColumn("Item"), new DataColumn("Qty"), new DataColumn("Rate"), new DataColumn("Amount") });
            dt.Rows.Add("Supply Of Electrical Equipments", "20", "3000", "60000");
            dt.Rows.Add("Construction of Bore Hole", "2", "350000", "700000");
            dt.Rows.Add("Construction of Fish Pond", "7", "45000", "315000");
            dt.Rows.Add("Purcahse of Water Pump", "2", "70000", "140000");
            Gridview1.DataSource = dt;
            Gridview1.DataBind();
        }
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
       
    }

    public void generatePDF()
    {
        string fileName = "Invoice" + DateTime.Now.ToString() + ".pdf";

        Response.Clear();
        Response.ContentType = "Application/pdf";
        Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName + ";");
        HtmlConverter.ConvertToPdf(getPanelHtml(), Response.OutputStream);
        Response.Flush();
        Response.Close();
        Response.End();
    }

    public string getPanelHtml()
    {
        StringBuilder sb = new StringBuilder();
        StringWriter tw = new StringWriter(sb);
        HtmlTextWriter hw = new HtmlTextWriter(tw);
        Panel1.RenderControl(hw);
        var html = sb.ToString();

        return html;
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        generatePDF();
    }
    public override void VerifyRenderingInServerForm(Control control)
    {
        /* Verifies that the control is rendered */
    }
