create a itextsharp pdf on aspx page.

Question

User-1651858287 posted

I am using a Wizard control I would like to create a pdf before the user

goes to ActiveStep 5.

I was wondering what I have to add to the page directive

<%@ Page Language="C#" ..../>

I am not using the code behind only on the aspx page.

void OnNextButtonClick(object sender, WizardNavigationEventArgs e) 

{

 

 

     if(Wizard1.ActiveStepIndex == 4)  

      {     

        //create pdf

      }

}

thanks.

You can create button and button click event and inside this event you can generate pdf using iTextSharp. See this article on iTextSharp to understand.

Hi sweetSteal,

 if(Wizard1.ActiveStepIndex == 4)   {     //create pdf     }

According to your description, I couldn’t understand your requirement clearly.

Do you mean you want to create a itextsharp pdf in code behind?

If this is your requirement, I suggest you could refer to this code about how to create a pdf file by itextsharp.

<asp:GridView ID="GridView1" runat="server"></asp:GridView>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DataTable dt = new DataTable();
                dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id"), new DataColumn("Name"), new DataColumn("Country") });
                dt.Rows.Add(1, "n1", "c1");
                dt.Rows.Add(2, "n2", "c2");
                dt.Rows.Add(3, "n3", "c3");
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            Rectangle rect = new Rectangle(500, 300);
            Document pdfDoc = new Document(rect, 10F, 10F, 10F, 0F);

            using (StringWriter sw = new StringWriter())
            {
                using (HtmlTextWriter hw = new HtmlTextWriter(sw))
                {
                    GridView1.RenderControl(hw);
                    HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
                    StringReader sr = new StringReader(sw.ToString());
                    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
                    pdfDoc.Open();
                    htmlparser.Parse(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();
        }
        public override void VerifyRenderingInServerForm(Control control)
        {
        }

If I misunderstand your requirement, please post more details information about your requirement.
