✅ There is already an open DataReader associated with this Command which must be closed first
I'm currently developing a Point Of Sale software in winforms c#. While working on cash management module I encountered such issue:
There was an issue with insert into TblCashOutReportItem: There is already an open DataReader associated with this Command which must be closed first.
I've spent too much time figuring out where the problem is so I would appreciate any help / solutions.
Thanks a lot
