Dear All,

I want to write a trigger which must act like KeyPress event of Visual Basic.

Basically what I want is "when any value is changed in a text box then a trigger should be executed".

I tried with Key-Others, Key-Edit but didn't succeeded.

If you have the solution, please guide me.

if you use another item on behalf of text item you can use list item and use when_validate_item trigger

Exactly right.

But there is about 1000 of distinct data; according to which I need to filter from another table.

I need to use Text Box only.

I want : When press 1 then the trigger should fire, again if press say 6 then the trigger should fire, again if press backspace then the trigger should fire and so on.

Please help me.

And Experts are also advised to confirm whether it is possible or so I do not waste my time over it.

Thanx in advance.

i'm not 100% sure about what what im going to say...but give it a try:

create a timer that copies the contents of the text_item_1 to the text_item_2 each time it expires lets say every 500 ms or something...

i think it will do the job, but also i think it will effect the performance of the form..

give it a try and let us know....

Oracle Forms is a block mode data handling system. It does not do "character by character". Use a Java thingy. There are examples, and links to examples, on the Oracle Forms web site.
