How to insert values using pushputtons in text item & fetch data based on

Question

Dear friends,
I want to insert values in the Text item using pushbutton e.g to insert 05CST884 into text item using pushbuttons '0' '5' 'C' 'S' 'T' '8' '8' '4' (alpha numeric buttons) in the layout editor and then fetch data based on the number entered with that of one in the table in the another text item2 in the layout editor.
Suggestions regarding how to develop and use effective triggers are welcome.

Answer 1

At the block level (for the control block where all your push buttons are, let's call it block1) create a WHEN-BUTTON-PRESSED trigger. Your [A-Z] and [0-9] buttons should be on a dedicated non-database datablock to reduce problems. As stated previously, this trigger should just contain the code:
:block2.text_item := :block2.text_item||get_item_property(:system.trigger_item, label);
Also on the pushbutton block, create a backspacve button with its own dedicated WHEN-BUTTON-PRESSED trigger containing:
if length(:block2.text_item) > 0 then :block2.text_item := substr(:block2.text_item, 1, length(:block2.text_item)); end if;
This will hopefully erase the last character entered.
block2 should be based on the database table (see Property Palette --> Database) you wish to query and text_item should be based on the database item which contains the code you entered. All the other database items you wish to displayshould also be added to block2.
Add another FIND push button to block1 with the code:
go_block('block2');
execute_query;
Without writing the whole thing for you, I'd suggest you get a decent Forms tutorial book to guide you through the basics (Oracle Forms Developers Handbook).
