How to add pages dynamically

Hi,
I have premium license .
I am able to write some data on page number - 0 .
Once the cursor reaches to the end of the page and if still more data present then it should write to next page.How I will get to know the when is the end of page?
My data is dynamic data ,not a constant data so not able to define number of pages.
Please help me to resolve this issue.

It depends on the data you are adding.

You need to keep track of the page dimension and the data (text/images) dimensions/position while adding them.

If it helps you can also check Change page size using Advanced properties
