Hi,
Thank you for reply.
Yes, I have surrogate and candicate key in my table.
However, I want to check duplication immediately after user pressed "OK" button (before actually save() is called). If the "key value" already exist, the will not be released.
So, do you think I should code these checking in BizObj.oRule.CheckExist() or some where in form/ok button?
Thank you
I am not the most powerful man in this world.
I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
