Current record issue

Question

Hi,
I have a data block in tabular format, displaying 10 records at a time with a scrollbar. There is a checkbox for each record. When the checkbox is checked/unchecked, I have to populate a summary field by looping through all the records including/excluding the record which was checked/unchecked. After this is done, I want the cursor to remain in the same record. Since i am using NEXT_RECORD to loop through all the records, the cursor comes to the last record. Then i used CURRENT_RECORD property to store the current record value and I reset the property after the looping is done. Now the cursor remains in the same record, but that record becomes the first record in the canvas meaning that the record scrolls upwards. How can we avoid this ? I want the canvas to remain in the same position as it was before checking/unchecking.
Regards,
Suresh

First of all, you don't have to loop over a block to sum something. That's what calculated items are for. Create a calulated item of type formula with something like the following as formula
CASE WHEN :BLOCK.CHECKBOX='J' THEN :BLOCK.VALUE ELSE 0 ENDCreate another calculated item of type summary which sums up the formerly created item.
If you still want to loop:
-Remember SYSTEM.CURSOR_ITEM before starting
-Remember GET_BLOCK_PROPERTY('BLOCK', TOPMOST_RECORD)
-After finished, do a GO_RECORD(<theFormelryRememberedSYSTEM.CURSOR_ITEM);
-Loop as long as GET_BLOCK_PROPERTY('BLOCK', TOPMOST_RECORD) is smaller then the remembered value and do a NEXT_RECORD;
