Currently I am having 2 radio button(Say A and B). On selection of the A , I am supposed to validate the textbox(say Name) and do not allow a null value on submit. However on selection of radio B, I can allow a null value on submit. How can I achieve this. Currently I am just enabling the switch button of the validation, but this does not allow me to submit the page if the radio button B is selected.
Here is a working example:
Page item P119_RADIO
Type Radio Group
List of Values Static, Values:
Display Value "Value A", Return Value "A"
Display Value "Value B", Return Value "B"
Page item P119_BUTTON
Type Text Field
Submit Button
action "Submit Page"
Validation
Type Item is NOT NULL
On page item P119_TEXT
server-side condition of type "Item (P119_RADIO) = Value (A)".

I have a Select list filter on the top of the page. I want its return value to get into any column which I create in IG report automatic DML process.
Suppose, Select list has a value "Step", when I add a row in IG report, that value should be saved into DB for one column which is hidden on UI.
I tried but sometimes it stores the value which I selected in Select list item as my last selection not the current one. Do I need to create Application item for this? Please help. TIA
In this case there is a table ig_tickes with a status column. On the page there is a page item P131_STATUS (select list) with values "OPEN" and "CLOSED". There is an interactive grid on table ig_tickets with column STATUS hidden. Functionality is that user selects a value from the select list and then clicks "Add Row".
Give the interactive grid a static id of "tickets"
Create a dynamic action on change of P131_STATUS with a true action of type "execute javascript code" and code:
var model = apex.region("tickets").call("getViews").grid.model;
model.getOption("fields").STATUS.defaultValue = apex.item( "P131_STATUS" ).getValue();
That's all there is to it.
I am using APEX 21.2.
The help says that "Display Only" Items do not store session state value and text fields with "Disabled" attribute set to yes do. But I tried to create an after header computation and set the value of a display only item and it worked. Is it wrong information or am I missing something?
Disabled
Specify whether this item is disabled, which prevents end users from changing the value.
A disabled text item still displays with the same HTML formatting, unlike an item type of Display Only, which removes the HTML formatting. Disabled text items are part of page source, which enables their session state to be evaluated. Conversely, display only items are not stored in session state.
I tried to create an after header computation and set the value of a display only item and it worked
Why wouldn't it work? It is you (a developer) who set it using a computation (which works), but end user can't modify its value as it is set to be display only so - users can just look at item's value.
A computation before rendering is always possible, that has nothing to do with session state. This is about how the item behaves on page submit.
With the "Display Only" item type you can control its behaviour on submit. Behaviour is the same for "Text Field" items that have the "Disabled" property set to on.
I did a quick test with a form on the EMP sample data set. Create a after header computation of type expression :P1_SAL + 1.
Test 1: Setting "set on page submit" on. The form renders with the salary item increased by 1. When page is saved, the new salary is saved for the record
Test 2: Setting "set on page submit" off. The form renders with the salary item increased by 1. When page is saved, the new salary is NOT saved for the record
Where did you see this help text ? I don't see anything about session state.
I have a form with items P1_APP and P1_USER.
P.S. P1_USER is select list.
Display John
Return 1
Display Andy
Return 2
I need to disable when user selects John.
When P1_USER = 'John', P1_APP should get disabled which is a multi select list.
I created dynamic action on P1_APP, True Action= Disable,Affected element P1_APP
Client condition : Item =Value
Item= P1_USER
Value= John
However this is not working.
I have used similar logic to disable interactive grid items and was able to do so. Why is this not working for form?
EDIT: In Value now i am putting 1 which is return value for John.
However when i select John. It disables P1_App upon clicking. But remains disabled even when i choose Andy.
This works for me using the following configuration.
Create form and report on EMP - everyone has access to that sample data, it is a good idea to post questions based on that.
In the form P3_DEPTNO is a select list with source
SELECT d.dname, d.deptno FROM dept d
Add a page item to my form P3_APP. This is a select list with "Allow multi selection" enabled. Select list has 2 static values.
Create a dynamic action on change of P3_DEPTNO.
Client side condition: Item = Value
Item: P3_DEPTNO
Value: 30 (note that this is the return value for SALES, not display value)
add true action of "Disable", affected item P3_APP
Click true action and select "Create Opposite Action". Save.
When I run this it work. Selecting SALES in the select list disables the item P3_APP and selecting something else enables it.
I have an item to enter email id, and two more items to get the values of first/last name and department of that user which we have given without refresh the page or without enter.
Item 1: ex : a...z#gmail.com (text field)
Item 2 : ex Mechanical (display only)
Item 3 : ex Abinnaya Moorthy (display only)
This should happen when we have given the email id and as soon as the cursor is out from email id the two item values should display.
I have used dynamic action but not getting exact output, please let me know.
On Item 1 make a following dynamic action:
Event: Change (I would recommend 'change', although based on your question, you might also be interested in 'Mouse Leave', although it would trigger DA even when no change in item value occurred, for example when someone just clicked on it and clicked away)
Selection Type: Item
Item: your Item 1
First true action: Execute PL/SQL Code
inserting values into your items Item 2 and Item 3, while using your Item 1 as a condition in WHERE clause
Page Items to Submit: your Item 1
Page Items to Return: your items Item 2 and Item 3
Second true action: Refresh
Selection Type: Item(s)
Item(s): your items Item1 and Item2
Let's say I have 1 field like an email field above. Then I have 50 display only fields that values are coming from (Source) SQL queries that depends on email field. How to refresh this fields without refreshing page, but also without Setting its value manually? I would only like to trigger them to perform their Source SQL query and refresh values on the page.
Setting their values by SetValue action will result in having same queries in Dynamic Action and in Source SQL Query for each field. Also for 50 fields DA would have hundreds of SQL lines and would become not maintainable.
assuming you are working on page 9, and the email field is :P9_EMAIL_ITEM, and the name fields are :P9_FNAME_ITEM and :P9_LNAME_ITEM
The email field is a text field (it doesn't matter what the source is)
The name fields should be display only, and in properties the setting "Based On" should be "Page Item Value", set the source property to type Null.
On the email text field, create a new dynamic action, set the When properties to: Event -> Change, Selection Type -> Item(s), Item(s) -> P9_EMAIL_ITEM
Under the dynamic actions you'll have a "New" event, with a "True" folder, and inside it a new action (probably "Show"). Change its action to "Set Value".
change the setting property so that "Set Type" will be "SQL statement", and write a statement with the following structure:
select FNAME_COLUMN, LNAME_COLUMN
from RELEVANT_TABLE
where EMAIL_COLUMN = :P9_EMAIL_ITEM
Under "Items to submit" select the P9_EMAIL_ITEM.
in the Affected Elements properties set Selection type -> Item(s) and Item(s) -> P9_FNAME_ITEM, P9_LNAME_ITEM
In "Execution Options" select NO for Fire on Initialization
what we did on step 5 is "refreshing" the relevant items, without refreshing the page
I just tested it out and here's what works very well:
On Item 1, create a DA on 'Loose Focus'
Create two true actions for 'Set Value', for both Item 2 and Item 3.
Select Settings > Set Type as SQL Statement.
Write query to fetch item 2 and item 3, base on item 1 (I suggest comparing lower cases of both to make it case in-sensitive.)
Items to Submit -> Item 1
And viola, it's done!
I try to set the value of a popup lov with a dynamic action "Set value" of type PL/SQL Function Body. This works with a select list, but not with a popup lov. How can this be done?
Let's assume your item is P1_ITEM and your LOV is
select display, return from table;
In standard Select List value is stored in #P1_ITEM.
In Popup LOV value is stored in #P1_ITEM_HIDDENVALUE, but displayed in #P1_ITEM.
So in dynamic action, you need to set two actions:
Set value 'return' from LOV with affected item P1_ITEM.
Execute JavaScript code
$("#P1_ITEM").val(display)
$('#P1_ITEM').val(&display.)
where display is the name of the field in SQL.
Hope it works.
