Either use the iTextSharp DLL provided in the sample.
OR
1. Download iTextSharp XML Worker DLL from here.
2. Add its reference to the project and then use the following code to export the GridView to PDF.
protected void ExportToPDF(object sender, EventArgs e)
{
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter hw = new HtmlTextWriter(sw))
{
//Hide the Column containing CheckBox
GridView1.Columns[0].Visible = false;
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
//Hide the Row if CheckBox is not checked
row.Visible = (row.FindControl("chkSelect") as CheckBox).Checked;
}
}
GridView1.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();
iTextSharp.tool.xml.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();
}
}
}
