Event while deleting a row in OO ALV GRID

Hi There,

I need to validate a row while deleting from an ALV grid and throw an error if that row can't be deleted. Right now I am doing it in the PAI of the screen in which ALV custom control is placed. Sequence of steps happening is…

- Delete a row

- Do some action

- Validation in PAI executed and an error message is displayed

But here unless I press enter or do other action the deleted line will not be appeared, is there any way to display this while issuing error message?

Thanks in advance,

Ram.
