How to generate multiple PDF dynamically through Itextsharp

Question

I am creating a c# method in which the user enters a data listing and assembles a pdf document for each data entered.

I’m using the iTextSharp library. On the first data it generates the PDF as expected, but when checking the code it stops on Response.End() and prevents you from reading the other data to generate the next Pdfs.

The doubt would be, how could I do to generate Pdfs uninterruptedly until all user inputs have been met?

Code:

protected void btn_pdf_Click(object sender, EventArgs e){          
    Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 40f, 0f);
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
    HTMLWorker obj = new HTMLWorker(pdfDoc);
    MemoryStream ms = new MemoryStream();
    PdfWriter writer = PdfWriter.GetInstance(pdfDoc, ms);
    pdfDoc.Open();
    pdfDoc.Add(table);

    pdfDoc.Close();
    Response.Clear();

    Response.OutputStream.Flush();
    Response.OutputStream.Close();

    Response.End(); // Nesse ponto ele para o loop
}

I don’t know where the loop ai... but you could do so:

protected void btn_pdf_Click(object sender, EventArgs e)
{    
    do{      
        Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 40f, 0f);
        PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
        HTMLWorker obj = new HTMLWorker(pdfDoc);
        MemoryStream ms = new MemoryStream();
        PdfWriter writer = PdfWriter.GetInstance(pdfDoc, ms);
        pdfDoc.Open();
        pdfDoc.Add(table);

        pdfDoc.Close();
        Response.Clear();

        Response.OutputStream.Flush();
        Response.OutputStream.Close();

        Response.End(); // Nesse ponto ele para o loop
    }
    while(textBox.TextLength>0 && textBox2.TextLength>0)
}

If that’s what I understand so will do while the fields are not all filled

PS: is just a suggestion, since the question is not clear...
