itextsharp pdf not showing - c#

I am using the following code to generate a PDF using iTextSharp from a GridView however the generated PDF is not visible to me. How can I view it in my html page?
GridView1.Visible = false;
SqlConnection sql = Connection.con();
sql.Open();
SqlCommand cmd = new SqlCommand("spGetSalesbyCustomer", sql);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#CustomerId", Convert.ToInt32(TextBox1.Text));
SqlDataAdapter adp = new SqlDataAdapter(cmd);
DataTable dd = new DataTable();
adp.Fill(dd);
GridView2.DataSource = dd;
GridView2.DataBind();
int cellCount = GridView2.Columns.Count;
sql.Close();
if (cellCount > 0)
{
GridView2.AllowPaging = false;
GridView2.DataBind();
BaseFont bf = BaseFont.CreateFont(Environment.GetEnvironmentVariable("windir") + #"\fonts\ARIALUNI.TTF", BaseFont.IDENTITY_H, true);
iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(cellCount);
int[] widths = new int[cellCount];
for (int x = 0; x < cellCount; x++)
{
widths[x] = (int)GridView2.Columns[x].ItemStyle.Width.Value;
string cellText = Server.HtmlDecode(GridView2.HeaderRow.Cells[x].Text);
//Set Font and Font Color
iTextSharp.text.Font font = new iTextSharp.text.Font(bf, 10, iTextSharp.text.Font.NORMAL);
//font.Color = new Color(GridView2.HeaderStyle.ForeColor);
iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new Phrase(12, cellText, font));
//Set Header Row BackGround Color
//cell.BackgroundColor = new Color(GridView2.HeaderStyle.BackColor);
table.AddCell(cell);
}
table.SetWidths(widths);
for (int i = 0; i < GridView2.Rows.Count; i++)
{
if (GridView2.Rows[i].RowType == DataControlRowType.DataRow)
{
for (int j = 0; j < GridView2.Columns.Count; j++)
{
string cellText = Server.HtmlDecode(GridView2.Rows[i].Cells[j].Text);
//Set Font and Font Color
iTextSharp.text.Font font = new iTextSharp.text.Font(bf, 10, iTextSharp.text.Font.NORMAL);
//font.Color = new Color(GridView2.RowStyle.ForeColor);
iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new Phrase(12, cellText, font));
//Set Color of row
if (i % 2 == 0)
{
//Set Row BackGround Color
//cell.BackgroundColor = new Color(GridView2.RowStyle.BackColor);
}
table.AddCell(cell);
}
}
}
//Create the PDF Document
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
int pages = pdfDoc.;
pdfDoc.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(pdfDoc);
Response.End();

Your question is a little unclear but if your code is correct (and I know it isn't 100% based on the seventh last line) then you're not actually adding your PdfPTable to the Document:
//Create the PDF Document
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
//Bind a writer to our document abstraction and our output stream
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
//Open the document for writing
pdfDoc.Open();
//This next line is a syntax error
//int pages = pdfDoc.;
//Add the table to the PDF
pdfDoc.Add(table);
//Close the document
pdfDoc.Close();
//ASP.Net/HTTP stuff
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
//Do not use this next line, it doesn't do what you think it does
//Response.Write(pdfDoc);
Response.End();

How to add an image background as watermark to the pdf file?

I Created ExportToPDF Button to export Gridview to PDF file, then how can I add an image background as watermark to the PDF file?
protected void ExportToPDF(object sender, EventArgs e)
{
using (StringWriter sw = new StringWriter())
using (HtmlTextWriter hw = new HtmlTextWriter(sw))
{
gvOrders.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
pdfDoc.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(pdfDoc);
Response.End();
}
}
One solution would be;
private static Image watermark_600
{
get
{
if (_watermark_600 == null)
_watermark_600 = Image.FromFile(HttpContext.Current.Server.MapPath(#"~/content/Images/watermark600.png"));
return _watermark_600;
}
}
then,
public static byte[] AddWaterMark(byte[] fileContent)
{
if (fileContent == null)
return null;
//create a image object containing the photograph to watermark
using (var img = new ImageFactory())
using (var imgWatermark = new ImageLayer())
{
img.Load(fileContent);
if (img.Image.Width < 750 && img.Image.Height < 750)
imgWatermark.Image = (Image)watermark_200.Clone();
else if (img.Image.Width < 1500 && img.Image.Height < 1500)
imgWatermark.Image = (Image)watermark_400.Clone();
else if (img.Image.Width < 2500 && img.Image.Height < 2500)
imgWatermark.Image = (Image)watermark_600.Clone();
else
imgWatermark.Image = (Image)watermark_800.Clone();
int x = Math.Abs((img.Image.Width - imgWatermark.Image.Width)) / 2;
int y = Math.Abs((img.Image.Height - imgWatermark.Image.Height)) / 2;
imgWatermark.Position = new Point(x, y);
imgWatermark.Opacity = 90;
img.Overlay(imgWatermark);
using (MemoryStream msbyte = new MemoryStream())
{
img.Save(msbyte);
return msbyte.ToArray();
}
}
}

How to export multiple gridviews into a single pdf file in dot net

I have 11 grid view in my page I want to export it into single pdf file, I searched this query and implemented the code which I got but it didn't work and generate pdf with black background only headers is showing not the content. Please provide me the code to export all 10 grid views into single pd

Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);
MemoryStream ms = new MemoryStream();
PdfWriter.GetInstance(pdfDoc, ms);
pdfDoc.Open();
for (int i = 0; i < gvpdf.Length; i++)
{
if (gvpdf[i].Visible)
{

pdfTbl.SpacingAfter = 20f;
foreach (TableCell headerTblCell in gvpdf[i].HeaderRow.Cells)

pdfTbl.AddCell(pdfCell);
}
}
pdfDoc.Add(pdfTbl);
}
}
pdfDoc.Close();
byte[] content = ms.ToArray();
Response.ContentType = "application/pdf";
Response.AppendHeader("content-disposition", "attachment;filename=report_" + ".pdf");
Response.BinaryWrite(content);
Response.Flush();
Response.End();
}
You may want to try another approach. Just read all your data from mentioned grids, store it in POCO classes and then use some library to convert this information into a PDF file with desired formatting.
Personally, I recommend a free and open-source library called QuestPDF (notice, I am its creator). It offers an easy to use fluent API, detailed documentation and a getting started tutorial showing how to generate an invoice document.

Multiple gridviews to single pdf using iTextsharp

I am trying to export multiple gridviews into single pdf using iTextSharp. I am looping through the gridviews and then looping through the rows of the gridview. The looping is going ok. But after pdf download, only the last gridview can be seen. It seems the gridviews are overwriting each other and only last one remains. Here is my code. What am I doing wrong?
protected void btnExportToPDF_Click(object sender, EventArgs e)
{
GridView[] gvExcel = new GridView[] { gridvw1,gridvw2,gridvw3 };
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);
for (int i = 0; i < gvExcel.Length; i++)
{
if (gvExcel[i].Visible)
{
PdfPTable pdfTbl = new PdfPTable(gvExcel[i].HeaderRow.Cells.Count);
foreach (TableCell headerTblCell in gvExcel[i].HeaderRow.Cells)
{
Font font = new Font();
font.Color = new BaseColor(gvExcel[i].HeaderStyle.ForeColor);
PdfPCell pdfCell = new PdfPCell(new Phrase(headerTblCell.Text));
pdfCell.BackgroundColor = new BaseColor(gvExcel[i].HeaderStyle.ForeColor);
pdfTbl.AddCell(pdfCell);
}
foreach (GridViewRow gvRow in gvExcel[i].Rows)
{
foreach (TableCell tblCell in gvRow.Cells)
{
Font font = new Font();
font.Color = new BaseColor(gvExcel[i].RowStyle.ForeColor);
PdfPCell pdfCell = new PdfPCell(new Phrase(tblCell.Text));
pdfCell.BackgroundColor = new BaseColor(gvExcel[i].RowStyle.ForeColor);
pdfTbl.AddCell(pdfCell);
}
}
//Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
pdfDoc.Add(pdfTbl);
}
}
pdfDoc.Close();
//Response.Clear();
Response.ContentType = "application/pdf";
Response.AppendHeader("content-disposition", "attachment;filename=report_" + startDate + "-" + endDate + ".pdf");
Response.Write(pdfDoc);
Response.Flush();
Response.End();
}
One of your errors is not an iText error; it's is a simple logical error that can be solved with common sense. The other error is weird. You aren't using the Response correctly.
protected void btnExportToPDF_Click(object sender, EventArgs e)
{
GridView[] gvExcel = new GridView[] { gridvw1,gridvw2,gridvw3 };
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f);
MemoryStream ms = new MemoryStream();
PdfWriter.GetInstance(pdfDoc, ms);
pdfDoc.Open();
for (int i = 0; i < gvExcel.Length; i++)
{
if (gvExcel[i].Visible)
{
PdfPTable pdfTbl = new PdfPTable(gvExcel[i].HeaderRow.Cells.Count);
pdfTbl.SpacingAfter = 20f;
foreach (TableCell headerTblCell in gvExcel[i].HeaderRow.Cells)
{
Font font = new Font();
font.Color = new BaseColor(gvExcel[i].HeaderStyle.ForeColor);
PdfPCell pdfCell = new PdfPCell(new Phrase(headerTblCell.Text));
pdfCell.BackgroundColor = new BaseColor(gvExcel[i].HeaderStyle.ForeColor);
pdfTbl.AddCell(pdfCell);
}
foreach (GridViewRow gvRow in gvExcel[i].Rows)
{
foreach (TableCell tblCell in gvRow.Cells)
{
Font font = new Font();
font.Color = new BaseColor(gvExcel[i].RowStyle.ForeColor);
PdfPCell pdfCell = new PdfPCell(new Phrase(tblCell.Text));
pdfCell.BackgroundColor = new BaseColor(gvExcel[i].RowStyle.ForeColor);
pdfTbl.AddCell(pdfCell);
}
}
pdfDoc.Add(pdfTbl);
}
}
pdfDoc.Close();
byte[] content = ms.ToArray();
Response.ContentType = "application/pdf";
Response.AppendHeader("content-disposition", "attachment;filename=report_" + startDate + "-" + endDate + ".pdf");
Response.BinaryWrite(content);
Response.Flush();
Response.End();
}
There might be some other issues, but I hope you understand the logical error:
You created a new PDF file with PdfWriter every time you entered the loop. You should only create one PdfWriter instance if you only want to create one PDF.
It's better to create the PDF in a MemoryStream, and then write the content of that stream to the Response object as a binary stream. I really didn't understand what you were doing there (and why you tried to do it that way).
I also introduced a SpacingAfter of 20 user units, otherwise it will look as if all tables all glued together into one big table.
There may still be some errors in the way you send the file to the Response, but this should already get you on your way. (Why aren't you sending the file size to the browser? You know that size, don't you? It's the number of bytes in the content object.)

Textbox doesn't appear while saving in pdf

I'm working on a asp.Net project where it requires to save in as pdf. I need to create a Label and a TextBox dynamically based on the data present in the database.
My problem is that when I try to save it in pdf,only Labels can be saved while the TextBox goes missing.
Below is my code for creating Label & TextBox dynamically.
for (int i = 0; i < dt.Rows.Count; i++)
{
TextBox txtSkills = new TextBox();
TextBox txtProficiency = new TextBox();
Label lblSkills = new Label();
Label lblProficiency = new Label();
txtSkills.ID = "txtSkills" + i.ToString();
txtSkills.Text = dt.Rows[i].ItemArray[1].ToString();
txtProficiency.ID = "txtProficiency" + i.ToString();
txtProficiency.Text = dt.Rows[i].ItemArray[2].ToString();
lblSkills.ID = "lblSkills" + i.ToString();
lblSkills.Text = "Skills:";
lblProficiency.ID = "lblProficiency" + i.ToString();
lblProficiency.Text = "Proficiency:";
Panel3.Controls.Add(lblSkills);
Panel3.Controls.Add(txtSkills);
Panel3.Controls.Add(lblProficiency);
Panel3.Controls.Add(txtProficiency);
Code for saving in pdf :-
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=" somename ".pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Panel3.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
Paragraph p1 = new Paragraph();
p1.SpacingAfter = 15f;
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
pdfDoc.Add(new Paragraph("Education"));
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
