Hello everyone -
Could somebody be so kind as to show me exactly how to use the set_item_instance_property and get_item_instance_property?
I have a checkbox named union_cb and a textitem named union_codes. Checkbox value is 1 for checked and 0 for not checked. How can I use these values to enable and disable the textitem? Thanks!
Steve

Hi,
You may do this in your when-new-record-instance, when-new-block-instance or pos-query triggers.
For e.g. you want that if Emapname is smith then Disable check-box then do as follows in say post-query /when-new-record-instance trigger:
Declare
Begin
if :empno='SMITH' then
set_item_instance_property('blockname.chekbox',Current_record,INSERT_ALLOWED,Property_False);
('blockname.chekbox',Current_record,UPDATE_ALLOWED,Property_False);
set_item_instance_property('blockname.chekbox',Current_record,NAVIGABLE,Property_False);
else
set_item_instance_property('blockname.chekbox',Current_record,INSERT_ALLOWED,Property_True);
set_item_instance_property('blockname.chekbox',Current_record,UPDATE_ALLOWED,Property_True);
set_item_instance_property('blockname.chekbox',Current_record,NAVIGABLE,Property_True);
End If;
end;
Remeber, this will work only if you have Insert & Update allowed property set as True at Block & Item level.
HTH

Hi Steve,
1st of all set_item_property is used to change the property of an item say text item in a block at 1 shot. But if 2 change the property of text_item individually in a block on navigation then use set_item_instance_property.
Similary get_item_instance_property that is used to retrieve data 1 by 1 if the item in a multirecord block.
use if union_cb=1 then
set_item_instance_property('union_codes,enabaled,property_off);
i hope this will solve your problem.
all the best.
write back.
regards
Ani
