Sample iTextSharp code that can be used to prevent content cutting over to the next page and being cut in half.

iTextSharp

// The problem is when you have a table, 
// which gets cut in half at the botto of one page, 
// and the other half shows up at the top of the next page.
// To prevent this, you can wrap your table in a container table (with a single cell)


PdfPTable containerTable = new PdfPTable(1);
containerTable .WidthPercentage = 100;

PdfPCell containerTableCell = new PdfPCell();

// Add your stuff to the ContainerTableCell.
containerTableCell.AddElement(yourOtherTable);
