Thanks for your response Karol. I guess I have to this way as I need the structure for printing the Balance Sheet purposes. As then I need to add the current balances and then generate the printout preview.
For the UI purposes I have a TreeView ActiveX which works fine with this added iSrNo field, but then the TV is generated in bits and pieces as and when the + sign is clicked.
I hope this was your question which I answered.
Kind regards
Bhavbhuti
