using (var db = new knowitCVdbEntities())
{
var theEmpl = (from p in db.EMPLOYEES
where p.username == strUserName
select p).FirstOrDefault();


if (theEmpl != null)
{


string sDirPath = Server.MapPath("~/PDF_WORD/Docs");



var ObjSearchDir = new DirectoryInfo(sDirPath);
if (!ObjSearchDir.Exists)
{
ObjSearchDir.Create();
}
string strFileName =
HttpContext.Current.Server.MapPath("~/PDF_WORD/Docs/Test." +
DropDownListDownloadCv0.SelectedValue.ToString() +
"");
var objfileinfo = new FileInfo(strFileName);
// step 1: creation of a document-object
var document = new Document(PageSize.A4);



if (objfileinfo.Exists)
{
File.Delete(strFileName);
PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
}
else
PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));



var sb = new StringBuilder();
var sw = new StringWriter(sb);

document.Open();
var hTextWriter = new HtmlTextWriter(sw);
var styles = new iTextSharp.text.html.simpleparser.StyleSheet();

const string classValue = "Body";
hTextWriter.AddAttribute(HtmlTextWriterAttribute.Class, classValue);
hTextWriter.RenderBeginTag(HtmlTextWriterTag.Div);

styles.LoadTagStyle("Body", "size", "60pt");

LabelFirstName.RenderControl(hTextWriter);
hTextWriter.RenderEndTag();

String strHtml1 = sw.ToString();

var hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
hw.SetStyleSheet(styles);

hw.Parse(new StringReader(strHtml1));

document.Close();


}
