Hi,
in a single record db block post_change trigger is fired after navigation takes place to another item and if changes are made, i have set this trigger on block level so that if any change is made in any of the block items it should enable a button
SET_ITEM_PROPERTY('block.item',ENABLED,PROPERTY_TRUE);
that is working ok..
the problem is that, suppose item_1 has value of 1
I change it to 5 and then again to 1 wihtout saving. Button gets enabled when i move to next item
i want the the button to remain disabled if the value is same as before..
is it possible???if yes how??
thanks in advnace..
ramis

You can save your prev value and try comparing with the new value.If it still remains same then you can disable the button.
something like following.
prevvalue = :item;(should be in a different trigger which fires before entering into the item).
here is the post_change trigger code.
If prevvalue = :item then
SET_ITEM_PROPERTY('block.item',ENABLED,PROPERTY_FALSE);
else
SET_ITEM_PROPERTY('block.item',ENABLED,PROPERTY_TRUE);
end if;
