Text not showing on pdf?

The problem I have is I am opening an existing pdf document, getting the 1st page, and writing some text on it using page.drawstring. Then I save the document. When I open the document in adobe reader, I don't see any text.

When I pick the "Select Text" tool, and choose "Select All", and then choose copy/paste into notepad, I see all my written text.

The only thing I can guess is that the text is written behind everything, is that possible? And how would I bring the text to the front if that's the case? I've tried using all sorts of coordinates to make sure that the text is written on the page, everything from (1,1) to (1100,1100).

I have done this numerous times in the past with no problems, but using a different pdf document. I am using the same code that I've used for the other 20 documents that I have done this with. Any ideas?

How are you drawing the text. This type of code is working for me:

PdfLoadedDocument doc = new PdfLoadedDocument(@"C:\test.pdf");
PdfPageBase page = doc.Pages[0];
PdfGraphics graphics = page.Graphics;
PdfTextElement text = new PdfTextElement();

text.Font = new PdfStandardFont(PdfFontFamily.Helvetica, 16, PdfFontStyle.Bold);
text.Text = "Hello World!";
text.Draw(graphics, 100.0f, 100.0f);

Hi Daniel,

Thank you for your interest in Syncfusion products.

Draw text on exiting pdf document

We can able to draw a text on a existing pdf document by using the "public void DrawString(string s, PdfFont font, PdfBrush brush, RectangleF layoutRectangle, PdfStringFormat format)" method.
