Which part is not working? On looking into the code, it seems you are showing an error message on entering the duplicate name.Code seems fine..

Are you Updating the Name  And Validating?

I task is duplicate name not enterd before the insert and before the update name should not change

So in case of update, are you not getting error message "Duplicate values" on entering the duplicate name? I do not see any issue with code probably someone else can find. Code will show error only when your prev and entered value is different and entered value already exists in system

thanks abhishek
