Hi,
I want disable the Addnew button after user click it, then user in add new record mode,
then I want to enable it until they save the record.
If I don't disable the Addnew button during add new record, I find that it may cause error when click
the Addnew button again.

So I put the code in the Addnew button click event, it occurs error.

Please advise.

Thanks.
