Hi,
I throws the exception when i try to add the pdfptable to the document.
Please find the code below.
if (pdfBodyTable != null && pdfBodyTable.Rows.Count > 0)
{
AgentDoc.Add(pdfBodyTable);
}
It throws the exception in the add method. Pdfbodytable has only 1 row which consist of multiple small tables.
