如何使用PDFSharp在多个页面上显示数据库中的行

我正试图从我的数据库生成一个PDF与所有的细节。这工作得很好……直到更多的数据行插入到数据库中，然后我的行运行到页面的末尾，然后突然消失。我一直在扯我的头发搜索解决方案在互联网上如何有我的行显示在多个页面，但我没有运气。在PDFSharp的论坛上没有对这个话题的支持(至少，不是我能找到的)，我真的需要这个工作。任何帮助将非常感激!

下面是我生成PDF的代码:(代码可以工作，直到我有很多行。)

public void PrintPDFDisplayingLogInformation(DataGridView dataPayments)
