Hi Deve,
Thank you so much for your help.
Yes, These are two methods which are envolved for dynamic row
creation/Deletion.
spiConnTable_create_data_context (...)
and
spiConnTable_commit_row(...)
Kindly find attached file for the code reference.
When I try to create(commit) row using MGSOFT browser,It says
no row creation.
Steps which I followed:
=======================
1. Select Rowstatus col as cretaeAndGo
2. Addrow
3. Commit
Message : commit Failed. OID failed during set operation(No
creation)
During this operation control never goes to the respective
method(spiConnTable_create_data_context
(),spiConnTable_commit_row() ) etc.
QUES :Is it require to write code for "RowStatus" states
handling?.
Please do let me know if anything is wrong in that.
(Please see the reference file )
Any help from anybody would be really appreciated.
---Regards
Devendra
