How are you coming with this?
Since I'm a newbie, here's how I'd try to approach this.
1) So we have the Selection List, say, :P1_SList
2) Then I'd create a Dynamic Action (DA) triggered on a change to :P1_SList.
3) The DA would have a PL/SQL procedure in the DA that computed (:P1_Disaplay_Number) 1 for text1, 2 for text2, ...
4) Then I'd have a display Condition -- a PL/SQL Function Body Returning a Boolean -- on each item (text1, text2, ...), something like, say for text3, ...
And so forth -- I hope my syntax is correct! So the item Condition determines whether the item displays.
BEGIN IF :P1_Display_Number <= 3 THEN RETURN TRUE; ELSE RETURN FALSE; END IF; END;
5) You could set :P1_Display_Number to 0 initially, so no items display until the selection is made and the DA triggered.
(I hope you don't have more than 10-15 of these text1 ... text15.)
Is what I have described what you are trying to achieve?
:P1_Display_Number is a text box so condition will be:
select count(1) into cnt from obe.v_schedule_parameter where id = (select id from obe.v_schedule_program where program_name=:P2_X);
IF cnt = 1 THEN
-- disable :P2_textbox
IF cnt = 2 THEN
Searching for pl/sql syntax to disable :P2_textbox.
Fields / items display (or are hidden) by the result of the "Condition" selection on the APEX page specification for that field / item. (You have all those tabs at the top: Identification, User Interface, Grid Layout, Label, ..., Condition, ...) Condition determines if the field is displayed. It defaults to "- Item Not Conditional" but if you click the drop down, there are 30-50 different conditions. Exists, NOT Exists, ..., Never, Always. If you select "PL/SQL Function Body Returning a Boolean," it will add an Expression 1 box to the GUI where you can write a "Begin ... End;" block to return TRUE or FALSE for the condition. It display if TRUE is returned, hides if FALSE is returned. (Someone else chime in here if I've left something out.)
This is a VERY slick feature of APEX. The only addiitons I could ask for would be: Positive, Negative and "Do what I mean".
good day! this is an OT message.
But i would like to ask if who among you who can deliver or conduct an Oracle Application Express Training.
Since we are looking an outsource / Part time Trainer.
If you can deliver or conduct this kind of training,please let know.
Or if you have someone in your mind which can deliver on this,we would appreciate if you will refer it to us.
You can reach through this email address: firstname.lastname@example.org
Mobile number's : +639 092438249. or +639 351908994.
We appreciate your response on this.
Training? It certainly wouldn't be me. This might not be the appropriate forum for this. But perhaps someone will reply and direct us to the appropriate venue.
I see you have already started your own thread for this. Good idea. But when you include your personal info in the forum, you expose yourself to SPAM, etc. So, I hope that doesn't happen to you.
