hELLOW to all,

i have an item with a trigger Key-Next-Item and below is the code i've written.

the problem is, it does'nt show the LOV and it only clears the item.

can someone tell me why..,

thanks..., whoever reply in this..,




BEGIN

SET_ITEM_PROPERTY('BLKINQ.TB_CONTRACTNO', LOV_NAME, 'LOVCONTNEW');
SET_ITEM_PROPERTY('BLKINQ.TB_CONTRACTNO',VALIDATE_FROM_LIST, PROPERTY_TRUE);

END;

make sure the LOV name is correct


Key-nxt-item trigger should be in some previous text item than the one in which you want to display LOV

better apply this code at when-validate-item trigger of previous item

BEGIN

SET_ITEM_PROPERTY('BLKINQ.TB_CONTRACTNO', LOV_NAME, 'LOVCONTNEW');
SET_ITEM_PROPERTY('BLKINQ.TB_CONTRACTNO',VALIDATE_FROM_LIST, PROPERTY_TRUE);

END; 

If that's all the code you've written then you shouldn't write it at all.
Either you're missing an IF statement - you want to set the lovname dependent the value of another item - in which case stick it in the WHEN-VALIDATE_ITEM trigger of that other item as itech suggested.
OR the code is pointless and those values should be set in the property palette.

As a general rule you should only use KET-NEXT-ITEM triggers for navigation and only if you need to do something unusual.

thank you "itech", and "cookiemaster". for your reply to my code., i will consider your advice.,

i've already found the solution to fire the property LOV_NAME and VALIDATE_FROM_LIST.

BEGIN

SET_ITEM_PROPERTY('BLKINQ.TB_CONTRACTNO', LOV_NAME, 'LOVNEWCONT');
SET_ITEM_PROPERTY('BLKINQ.TB_CONTRACTNO',VALIDATE_FROM_LIST, PROPERTY_TRUE);

GO_ITEM('CMDPRINT');

END;

i just put a GO_ITEM() function to fires the property VALIDATE_FROM_LIST...,

well the use of

key-next-item
and
go_item

is not recommended if you have some alternate ways to achieve the same thing.

better re-write the code in when validate item trigger if you want to change the LOV at runtime
