I am using licensed version 184.108.40.206 grind in my project. I used some scientific formulas in that grid. When i update first time its updated all the rows, when i modify and updated second time its showing some error "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records.".
Why its giving this error. First time its updating , second time its showing the error.
Can you give me the solution for this issue.
