Forms :: Checkbox In Multi-row Block And Scroll Bar

I have a multi row datablock with scroll bar. In each record I have a checkbox (let's call it check_record), and above these checkboxes, there is a checkbox to check/uncheck all the checkboxes (let's call it check_all).

If all the "check_record" are checked, the "check_all" must be automatically checked, else if one "check_record" is not checked, it will be unchecked.

To do that, I have put a loop in the WHEN-CHECKBOX-CHANGED of "check_record" to loop over all the "check_record" and see if they are checked or not.

Normally, this loop will automatically go to last record. But to go back to the selected record (where the "check_record" was clicked), I have used go_record with the record ID.

==> No problem in that, it's working fine.

Now, this is my problem: When clicking on a "check_record", the scroll bar moves to show the selected row in the first (or last) VISIBLE row in the data block, and that's because of using "GO_RECORD(<CURRENT_RECORD>)".

Example: if I select the third record in the data block, the scroll bar moves to show it in the first visible row.

Is there a way to "freeze" the scroll bar and keep the record in its initial position in the data block?
