Solution 1

it seems your html is incorrect, try with simple html first

C#

string htmlstr =  @"<html><body>
                   <h1>My First Heading</h1>
                   <p>My first paragraph.</p>
                   </body>
                   </html>";

if it is success you can fix the issue in your html.

hope this helps

C#

protected void imgbtnPDF_Click(object sender, ImageClickEventArgs e)
   {

       string imagepath = Server.MapPath("Images");
       Response.ContentType = "application/pdf";
       Response.AddHeader("content-disposition", "attachment;filename=CellzoneSalesReport.pdf");
       Response.Cache.SetCacheability(HttpCacheability.NoCache);
       StringWriter sw = new StringWriter();
       HtmlTextWriter hw = new HtmlTextWriter(sw);
       GridView1.AllowPaging = false;
       GridView1.DataBind();
       GridView1.RenderControl(hw);
       StringReader sr = new StringReader(sw.ToString());
       Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
       HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
       PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
       pdfDoc.Open();
       pdfDoc.Add(new Paragraph("HEADER"));
       htmlparser.Parse(sr);
       pdfDoc.Close();
       Response.Write(pdfDoc);
       Response.End();
   }

Try this. I hope this will help. :)

sorry .. i get error

htmlparser.Parse(sr);//red line

same error as above...

DLSU-D Student 22-Apr-14 10:35am

I used this code for exporting gridview.

protected void Page_Load(object sender, EventArgs e)
{
string strQuery = "SQLCOMMAND HERE";
SqlCommand cmd = new SqlCommand(strQuery);
DataTable dt = GetData(cmd);
GridView1.DataSource = dt;
GridView1.DataBind();
}
private DataTable GetData(SqlCommand cmd)
{
DataTable dt = new DataTable();
String strConnString = System.Configuration.ConfigurationManager.ConnectionStrings["ProjectNameConnectionString1"].ConnectionString;
SqlConnection con = new SqlConnection(strConnString);
SqlDataAdapter sda = new SqlDataAdapter();
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
try
{
con.Open();
sda.SelectCommand = cmd;
sda.Fill(dt);
return dt;
}
catch (Exception ex)
{
throw ex;
}
finally
{
con.Close();
sda.Dispose();
con.Dispose();
}
}
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}

protected void OnPaging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
}

Try this bro. :)

Make sure your itextsharp.dll is in folder Bin. :)

utm 22-Apr-14 11:00am

yes i have...i add it as reference.

utm 22-Apr-14 10:44am

there no problem of binding the grid view...i have use all above code..but not working..
i have problem in itextsharp...somewhere HTMLWorker htmlparser = new HTMLWorker(pdfDoc);and
htmlparser.Parse(sr); but i am not getting it ... vs intellisense ask for stream reader in place of string reader ...in htmlparser.parse(?)..
