iTextsharp Error

Question

Hi,

I am trying to add a pdfptable to a itextsharp document. Since the data is large it throws the error "Object reference not set to an instance of an Object".

However it works fine with small data.

please provide a solution for the issue.

 

Please find the stack trace below:
