hello every one,
I am having a text_item1 which gets its value from an LOV, and once the user selects
from an lov I want to get a value in text_item2
based on value in text_item1
(select describtion into :text_item2 from table where :text_item1=code)
I used post-change but it didn't get the value
when-validate_item worked but it only fires when I save
kindly respond as soon as possible

As far as I can tell, POST-CHANGE should not be used; it is here for backward compatibility.

WHEN-VALIDATE-ITEM trigger is the right one. It fires during item validation process (which is, for example, when you navigate out of the item or - as you noticed - when you save changes, but NOT ONLY then).

Then you must be doing it wrong.

If possible, copy/paste your code over here. Before doing it, please, have a look here (will take only 10 seconds of your time).

You realise that code does the opposite of what you originally posted?
If when-validate-item only fires when you save then that'll be because of the form level Validation Unit property. Read the form builder help topic on it.

However - why don't you just use the LOV to populate the other item?

Dragging? Dragging what? 0 width LoV columns? Did you try to "drag it"?

The LOV is the correct way to do - try it.
