Glad you got it Nadya. I knew it was one of them, just couldn't remember which. As a rule, I always include the following in my forms:

SET TALK OFF
SET TALK NOWINDOW
SET ECHO OFF
SET DELETED ON
SET SAFETY OFF
SET NOTIFY OFF
SET REPROCESS TO 1 SECOND
SET CENTURY ON
SET EXCLUSIVE OFF
SET MULTILOCKS ON

>>>Hi everybody,

>>>If I set columns in a grid (or the whole grid itself) to be ReadOnly and then try to type something, I get a message: 'This control is read-only'. I also get beep signal. Today for some reason it starts irritating me. Is there a way to prevent this message from appearing? I tried checkbox.click event (for this particular column it was check box), but with no lack. I was thinking about adding this code into column.click itself, but not sure, it helps. Could you point me in right direction, if it's doable?

>>>Thanks in advance.
