Post subject:  Set table border on existing pdf template
Hi, I have a pdf document template with predefined table and rows/columns. I use pdfsharp to fill the form fields with data (as demonstrated in your samples). I was able to set font of the content. Now I need to set a border visible, is this possible or do I have to use MigraDoc and draw the whole template from scratch?

Thanks in advance

I cannot answer that with the information I have. You do not show your template. Can you add the borders to the template?

My mistake, I didn't specify that I want to add border only to those rows I add data to. In my template there is a table with predefined 10 rows, 3 columns per row. I fill some of those rows (usually not more than 2) programmatically based on the data I get from a web service. I didn't think that posting an image of the template would give any more information, as it contains a company specific data and a blank table (no borders). I am actually interseted only in bottom border of the table row.

There are no tables in PDF.
You can easily draw some lines based on co-ordinates saved in your code. Disadvantage: Changes of the template will require changes of the code.

Getting co-ordinates from code would be better, but I think it is much more complicated.

Thanks, do you have any example for this or know which of the downloaded samples includes simplest form to do this?

Use gfx.DrawLine() as in this sample:
http://www.pdfsharp.net/wiki/Graphics-s ... le_lines_0

You can use XUnit.FromMillimeter or XUnit.FromInch and others for unit conversions.
Code:
gfx.DrawLine(XPens.DarkBlue, XUnit.FromMillimeter(0), XUnit.FromMillimeter(150), XUnit.FromMillimeter(210), XUnit.FromMillimeter(150));

Thanks. I also found that I can use Elements collection on the PdfTextField and a key "/Rect" to get coordinates. But there is something strange, my lines are drawn as if I got coordinates from the bottom of the page.

Maybe WorldToDefaultPage can help:
Code:
rect = gfx.Transformer.WorldToDefaultPage(New XRect(New XPoint(100, 400), New XSize(350, 150)))


If not then you may need a different transformation.

Very strange, I use the following to get coordinates of text field:
Code:
PdfArray coordinates = (PdfArray)txtField.Elements["/Rect"];
double x = double.Parse(coordinates.Elements[0].ToString(), System.Globalization.CultureInfo.GetCultureInfo("en-US"));
double y = double.Parse(coordinates.Elements[1].ToString(), System.Globalization.CultureInfo.GetCultureInfo("en-US"));
double w = double.Parse(coordinates.Elements[2].ToString(), System.Globalization.CultureInfo.GetCultureInfo("en-US"));
double h = double.Parse(coordinates.Elements[3].ToString(), System.Globalization.CultureInfo.GetCultureInfo("en-US"));
xg.DrawLine(XPens.Black, x, y, w, y);


It seems as I get coordinates from the bottom of the page and when I call the DrawLine it draws from the top.

So instead of "y" you have to use something like "842 - y".
842 is the height of a DIN A4 page. You have to use the height of your template page.
