ASP.NET - Exporting Textbox to pdf using iTextSharp

i did ,exporting gridview to pdf, it  working well , but i need to export plain textboxes instead of gridview
here is code i changed

Response.ContentType = "application/pdf";

Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");

Response.Cache.SetCacheability(HttpCacheability.NoCache);

StringWriter sw = new StringWriter();

HtmlTextWriter hw = new HtmlTextWriter(sw);

//GridView1.AllowPaging = false;

//GridView1.DataBind();

//GridView1.RenderControl(hw);

TextBox1.Text = "SATHEESH KUMAR AVULA";

TextBox1.DataBind();

TextBox1.Visible = true;

TextBox1.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();

htmlparser.Parse(sr);

pdfDoc.Close();

Response.Write(pdfDoc);

Response.End();

First it was given me Error  :-

RegisterForEventValidation can only be called during Render();

I solved it by making 

EnableEventValidation="false"

Than Second Error:-

The document has no pages.

pls give some solution for that am really stuck for long days , my destination is i want to download whole Membership form in pdf format how can i ??????

thanks

The thing is that ASP.NET has a very strong page lifecycle. RegisterForEventValidation can only be called during the Render phase of the page lifecycle. That means it will fail when calling RenderControl() at any other moment.
However, my first focus would be on GridBuilding. If that has anything on it that can cause a PostBack, then that will have to be turned off before rendering.

You have to turn the eventValidation off in order for this to work.

You can do this in the web.config file but in this case the eventValidation will be turned off for all the pages.

 <pages enableEventValidation ="false" ></pages>

or Add the @Page Directive in code behind file.

 EnableEventValidation ="false"

<%@ Page Language="C#" AutoEventWireup="true" Debug ="true" EnableEventValidation ="false" CodeFile="Default.aspx.cs" Inherits="_Default" %>
