Hi,

I am getting below error when I am generating a report using RDLC, and getting the data into the DataTable for one of my Windows application. My report works sometime and sometime don't. Suppose, I have to display 20 rows for that I am retrieving the data in datatable using foreach() and this breaks any of the occurance of loop (i.e 5th or 7th or 12th) and throws exception.

ERROR:

System.Data.OleDb.OleDbException: Unspecified error
