I am converting aspx page to pdf. There are textarea html elements which dynamically grow as you type (using jquery plugin). So there could be 1 pdf page or 10 pages because of the dynamic textareas. I need to place digital signature into pdf after the last textarea on the last pdf page. The digital signature api takes x,y coordinates (I know I know lame right?). So I'm thinking find last textarea element position then insert digital signature after it? Or if I can have a footer only on the last pdf page and add digital signature here I think this would work. Any other suggestions?

Hi,

Yes. You will need to handle the control's AfterRender event. Inside the event you will need to get the HtmlToPdfResult object:

http://www.essentialobjects.com/doc/1/eo.web.aspxtopdf.afterrender.aspx

Once you have that object, you can do something like this:

Code: C# 
//Get the HtmlElement object. There are a number of GetElementByXXX
//methods, you can check the documentation to see which one fits you 
//the best
HtmlElement e = result.HtmlDocument.GetElementById(element_id);

Once you have the HtmlElement, you can use the element's Location and Size to determine the exact location (page index, x/y location) and size of the element.

Thanks!
