Hello,
I have a text item and depending on the value of this text item, I wish to have some other text items not displayed.
I'm using when-validate-record to do this :
if :my_block.text_item1 = '1' then
set_item_property (:my_block.text_item2, displayed, property_false);
end if;
I have no problem when I'm creating the frist record but when I wish to create a new record, I don't know how to clear the block and have all the items displayed again. The message I'm getting is that there is no navigable items in the block.
I have the same problem when querying records. The first one works fine (using when-new-record-instance with the same set_item_property instruction) but I get the same message when I want to see the next record.
Do you have any solution?
This is urgent.
Thanks a lot.
Liisa

hi,
well you could try this. For the first part of your question.
A.
1. to clear block use "clear_block;"
2. you need to set NAVIGABLE to true for one of your text items. eg. Go_block('block');
execute_query;
before it can go to a block, an item must be navigable within that block, otherwise forms has "nowhere to go".
B. Create a prog unit based on your code above;
reference this in a POST_QUERY trigger;
hope this helps you as bit.
n,
