The best way to achieve your requirement is by using “PdfHTMLTextElement”. But as we did not implemented Event handlers in “PdfHTMLTextElement” your requirement could not be currently achieved. We have logged a feature request to implement the Event Handlers in “PdfHTMLTextElement”. Once this feature is implemented we can achieve your requirement, we will let you know once this feature is implemented.

We could manually remove that from the html string that we are drawing to draw the next block.
Kindly share your requirement to draw the next block elaborately. Whether the (paginated HTML content) block drawn on the same page or next page. So, it will be useful for us to investigate further on this and assist you with a better solution at the earliest.
