Conditionally disable items in tabular form

I built a tabular form . One of the column has dropdown called 'Type'. If users select type 'R' i want to disable 2 fields(text3 and text4) and in type is 'P' i want to disable other 2 fields(text5 and text6).
I started off by including the foll. in the HTML header for page
<script language="JavaScript1.1" type="text/javascript">
function disableItem(pThis) {
//alert(html_SelectValue(pThis));
var l_soft = (html_SelectValue(pThis)== 'R');
html_disableItems(l_soft,'TEXT3','TEXT4');
</script>
In the Column Definition of LOV, I added the onchange="javascript:disableItem(this);" for Element Attributes.
The problem is, this code is disabling column header for TEXT3 and TEXT4 rather than disabling the fileds. Can someone help me to make this work.
Thanks in advance.

I'm using a similar thing in my app and it works fine. I have the disableFields() function in HTML header. Then in footer, I have something like:
<script language = "javascript">
if($x('type').value=="P" || $x('type').value=="R")
{disableFields();}
</script>
Make sure the item named "type" is a select list with submit, and there is a page branch going to the same page. Also, in javascript, everything is case sensitive...make sure ur item names are in the proper case.

How to generate specific # of items in tabular form from one item

Looking to display or render additional elements to a tabular form based on the number entered in a quantity field. ie. if someone orders 10 items, I would like to have 10 tabular items display on blur, so the operator can enter the data in those fields for the 10 items. Then of course I need all items processed on submit.
Is there a way to do this so the # of line items are rendered after a quantity has been entered to match or is this something that would have to be done with display values and a set number of items already on the page?
Thanks

Hi Naresh,
You need to use Billing Plans for Service Contracts Scenario to create BRI items.
In the Billing Plan - you can assign whether it is a Periodic Billing or Milestone Billing. Then you need to assign this billing plan to item categories. So based on the period (monthly,quarterly,yearly) - the BRI items will be generated.
So Please try using Billing Plans for your scenario. As you mentioned earlier, you are using ECC for all Billing purposes. So the system will create one Debit Memo Request document per Contract and it will each line item for each of the BRI's in Service Contract. System will not generate one DMR per BRI item.
You can check the BRI items generated at the item level --> Billing Plan Tab page (Assignment Block in Web UI).
Hope this helps.

How to retain value in LoV item in Tabular Form, after Page Refresh

Hi,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, 2nd item(column) in tabular form, that LoV should get populated based on user's selection value in first item LoV.
1. So how do I refer to the value, that user selected in first item's LoV? I will have to use this value as reference in LoV query of my 2nd item ( on this tabular form)
2. Everytime I select value in first item LoV, page gets refreshed, as my requirement is to calculate 2nd item's LoV based on selected value in first item. So after this page refresh, first item LoV loses its value that was selected before the page refresh happened. So how do i retain this value in first item LoV? I have an unconditional process, that on every submit(refresh) of page, I set all my items with their corresponding values. But problem is what do i mention there to refer to this first item ( of type LoV) of tabular form?
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Please help.
Thanks and Regards,
Ravi.

Hi Rave,
You will have to use Javascript and Ajax to change the values as ApEx submissions will lose your results unless they are saved into the database.
Remember, that as you are using a tabular form there will be lots of items called f01, fo2, fo3 etc on the page (one per row).

I understand that the add row button is currently doing a submit.
To not submit the page you need a dynamic action on the page.
Does the javascript function addRow do what you want?
Otherwise have a look at the following two threads Add row in manual tabular form using dynamic action and Accessing Tabular Form & Add Elements to Collection without Page Submit.
You're process could be something like:
Add the new values to the collection using the idea's in the second thread and at the same time add the new row.
And as second action refresh your tabular form.
If you get stuck set up what you have done on apex.oracle.com using the tables from the demo application.

Failed validation highlights entire column in tabular form

Hi,
I have a tabular form where one of the field is a date field. I need to ensure that that the date selected or entered falls in the correct range of another page item P6_WEEK_ENDING. Here is my code.
DECLARE
     last_week_fri      DATE;
     this_week_fri     DATE;
     in_range NUMBER:=1;
     ret_bool BOOLEAN := TRUE;
BEGIN
     -- Get current end of week ID
     this_week_fri:= CONVERTDATE2(:P6_WEEK_ENDING);
     SELECT CONVERTDATE2(this_week_fri-7) INTO last_week_fri FROM DUAL;
     FOR i in 1..apex_application.g_f03.count LOOP
          IF apex_application.g_f03(i) IS NOT NULL THEN
               CASE
                    WHEN CONVERTDATE2(apex_application.g_f03(i)) >= CONVERTDATE2(last_week_fri) AND CONVERTDATE2(apex_application.g_f03(i)) <= CONVERTDATE2(this_week_fri) THEN
                         null;
                    ELSE
                         in_range:=0;
               END CASE;
          END IF;
          if in_range != 1 THEN
               ret_bool:= FALSE;
               EXIT;
          END IF;
     END LOOP;
     return ret_bool;
END;Where
convertdate2 takes date format and outputs date in dd-mm-yyyy format.
apex_application.g_f03(i) is the date field.
Now it all works well except when my validation fails, it highlights the entire column instead of highlighting the only the bad entries.
I have my execution scope as : Created and Modified Rows, tried changing it with no luck.
Many thank.
Environment: APEX.4.1.1 using Sand theme

Taepodong ,
I assume this is a validation. When you first created the validation, you either selected a page item or tabular form. If you selected the latter, you then selected the tabular form to which the validation would apply. On the next screen, you were asked to "Identify the validation level:" I am guessing that, at that point, you selected "Tabular Form Row" rather than "Column" The former will highlight the entire row, while the latter will only highlight the column which was specified.

Set value in tabular form field with dynamic action

Hi Guys,
I have a dummy field in a tabular form which I am trying to use to populate another field in the tabular form when it is changed.
In the tabular form I have an ITEM_ID field. Each item_id has an ITEM_NAME which is the dummy field as it is not a field in the database table.
When the user enters an item name, I would like something like a dynamic action to fire, populating the ITEM_ID.
e.g User enters part no ABC into the dummy field. When they tab out, I want the value to the item_id field on the tabular form row to be populated based on a SQL query in a similar fashion to how it can be done with dynamic actions on text items on a form.
I am using APEX v4.0.0
Thanks in advance
Chris

Hello Chris,
Why can't you use Select List Item on tabular form, which will display all item_names and return item_ids?
If the list is huge and you need users to type & search, then you can use Pop-up LOV item.

Not only does APEX not provide support for file browse items in tabular forms (which are horrible anyway; even more so with an ugly file picker in every row), but file path information is not available in standard browser configurations (or at all in most browsers). As has been noted in many previous threads on this topic:
>
For security/privacy reasons recent versions of browsers by default do not send local file path information from File Browse items to the server, nor expose the file path in the control's JavaScript methods. Firefox, Safari and Chrome only provide the filename. IE6 & IE7 still yield the path in Windows format. IE8+ and Opera have adopted an irritating approach of replacing the path with a wholly imaginary "C:\fakepath\"—and this monstrosity has sadly had to be enshrined in the HTML5 spec...
Changing IE's security config setting "Include local directory path when uploading files" enables the path to be exposed in IE, but unless you're working in an intranet environment where: IE is the only browser used; it's possible to make remote changes to this setting on every desktop; and this won't break/expose anything else, then trying to achieve this is pointless.

Go right back to the start and explain what this is all about. We need to know what the ultimate goal is in order to determine what use—if any—can be made of APEX here.

Validate field in tabular forms apex 4.2

Hi.
i need help doing next validations :
1.- i have a product_item field (wich is a lov and user choose one value), so i need to call a function (sending it the selected value product_item) that will return me some data about the product i selected, for example :
if the function return 'A' then
disable the next item on tabular form, lets say quantity
else
enable the next item on tabular form, lets say quantity
end if
2.- i need to determine the result of two items operations:
total := final_quantity - start_quantity
the user will introduce start and final quantity and i will determine the total.
any ideas ?
i am new on apex and need to do this on tabular forms.
thanks in advance.

Thomas,
Is this a standard APEX tabular form validation, or a custom PL/SQL based validation? It might be easiest to diagnose what's going on there, if you could replicate this issue on apex.oracle.com, and point us to an example.
Thanks,
Marc

I solved it.
I modified a bit my code "On load Page". In case of LOV i have changed this condition
if (l == undefined) {
          document.wwv_flow.f03.disabled = true;
      }with this
if (l == 105) {
          document.wwv_flow.f03.disabled = true;
      }I don't know why 105 instead of undefined, but this works. I give 105, with alert on length.

How to refresh page after selecting value from LOV item , in a tabular form

Hi ,
I have a tabular form, which contains 2 items(columns), of type "Select List - named LoV".
Now, couple of issues here.
1.
2nd item(column) in tabular form, that LoV should get populated based user's selection value in first item LoV. So how do i refer to the value, that user selected in first item's LoV? I will have to use this reference in LoV query of my 2nd item ( on this tabular form)
2.
How can we refresh the page, when user selectes value in first item ( from LoV). As this is a tabular form, here item type is Select List, we dont have an option to pick item type as Select List with Submit. So problem is that when user selects value for item 1, refresh does not happen and item 2 LoV does not get populated as per user's selection in item 1.
Please help here. Would be really appreciated.
Thanks and Regards,
Rave.

Thanks Ben and Dan for your responses.
Ben, your solution helped me with refresh of page, as page got submitted.
This answers to my 2nd question. However, I still need to know first question, which basically is, how do i refer to the value, that user selected in first item LoV.
Issue is, I selected the value in first item LoV, it got submitted and page fot refreshed. But after page refresh, first item LoV loses its value that I had selected last time. It does not retain the selected value after refresh.
I have an unconditional process, that on every submit(refresh) of page, I set my items with their corresponding values. But problem is what do i mention there to refer to this item.
I looked in view source of my page, this item is referred as f03.
So i used "apex_application.g_f03", to set this item to its value, in my uncoditional submit process. But it did not work. I tried to refer this item as "f03" in this unconditional submit process. But still it did not help, the selected item loses its value after page refresh(submit).
Any help here would be really appreciated. Please suggest how do we refer to this item's selected value.
Thanks and Regards,
Ravi.

Enable/Disable item Based Value from Select in Tabular Form

Hi Guys
I want to Disable text field in Tabular form, Based on the Select List Item Value.
Let's Say
I'm having one select lista and text box in each record in tabular form.
Select List having 2 items ... Add Text(return value 1) and No Text(return value 2)
if value =1 then i want to enable text box , so user can enter value.
if value=2 then text box won't allow to add text or will become disalbe.
Please Help
Thanks

Hi,
You can do this by using a small java script
<script language="JavaScript" type="text/javascript">

</script>Here P2_Text is the text box whose value I am enabling or disabling based on the selected value from a List box. On The list box I have onChange="javascript:FldEnableDisable(this.value)" ( You can specify this under HTML Form Element Attributes)
Thanks,

Across row validation in tabular form and across items in row validations.

Hi,
We are upgrading to APEX 4.0.
I need to create a tabular form that will have a start date and an end date. FOr each new row or updated row I need ensure its start date is after the end date of all rows already entered and its end date is after the start date of row being entered. Also that if no end date is entered then no other rows can be found with a null end date.
SO I need across field validations with in a row and across row validattions. That is I need rowset validations as well.
Is it possible to do this with APEX? WHat kind of tabular solution would allow these type of validations. How might these validations be done?

Okay, Here's a quick rundown on how to build a manual form using APEX_ITEM and collections. The process goes in 4 steps: gather the data, display the data, update based on user input, then write the changes. Each step requires it's own piece of code, but you can extend this out as far as you want. I have a complex form that has no less than a master table and 4 children I write to based on user input, so this can get as complex as you need. Let me know if anything doesn't make sense.
First, create the basic dataset you are going to work with. This usually includes existing data + empty rows for input. Create a Procedure that fires BEFORE HEADER or AFTER HEADER but definitely BEFORE the first region.
DECLARE
v_id     NUMBER;
var1     NUMBER;
var2     NUMBER;
var3     VARCHAR2(10);
var4     VARCHAR2(8);
cursor c_prepop is
select KEY, col1, col2, col3, to_char(col4,'MMDDYYYY')
    from table1
    where ...;
i         NUMBER;
cntr      NUMBER := 5; --sets the number of blank rows
BEGIN
OPEN c_prepop;
    LOOP
      FETCH c_prepop into v_id, var1, var2, var3, var4;
      EXIT WHEN c_prepop%NOTFOUND;
        APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => v_id, --Primary Key
        p_c002 => var1, --Number placeholder
        p_c003 => var2, --Number placeholder
        p_c004 => var3, --text placeholder
        p_c005 => var4 --Date placeholder
    END LOOP;
CLOSE c_prepop;
for i in 1..cntr loop
    APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => 0, --designates this as a new record
        p_c002 => 0, --Number placeholder
        p_c003 => 0, --Number placeholder
        p_c004 => NULL, --text placeholder
        p_c005 => to_char(SYSDATE,'MMDDYYYY') --Date placeholder
end loop;
END;Now I have a collection populated with rows I can use. In this example I have 2 NUMBERS, a TEXT value, and a DATE value stored as text. Collections can't store DATE datatypes, so you have to cast it to text and play with it that way. The reason is because the user is going to see and manipulate text - not a DATE datatype.
Now build the form/report region so your users can see/manipulate the data. Here is a sample query:
SELECT rownum, apex_item.hidden(1, c001), --Key ID
     apex_item.text(2, c002, 8, 8) VALUE1,
     apex_item.text(3, c003, 3, 3) VALUE2,
     apex_item.text(4, c004, 8, 8) VALUE3,
     apex_item.date_popup(5, null,c005,'MMDDYYYY',10,10) MY_DATE
FROM APEX_COLLECTIONS
WHERE COLLECTION_NAME = 'MY_COLLECTION'This will be a report just like an SQL report - you're just pulling the data from the collection. You can still apply the nice formatting, naming, sorting, etc. of a standard report. In the report the user will have 3 "text" values and one Date with Date Picker. You can change the format, just make sure to change it in all four procedures.
What is critical to note here are the numbers that come right before the column names. These numbers become identifiers in the array used to capture the data. What APEX does is creates an array of up to 50 items it designates as F01-F50. The F is static, but the number following it corresponds to the number in your report declaration above, ie, F01 will contain the primary key value, F02 will contain the first numeric value, etc. While not strictly necessary, it is good practice to assign these values so you don't have to guess.
One more note: I try to align the c00x values from the columns in the collection with the F0X values in the array to keep myself straight, but they are separate values that do NOT have to match. If you have an application you think might get expanded on, you can leave gaps wherever you want. Keep in mind, however, that you only have 50 array columns to use for data input. That's the limit of the F0X array even though a collection may have up to 1000 values.
Now you need a way to capture user input. I like to create this as a BEFORE COMPUTATIONS/VALIDATIONS procedure that way the user can see what they changed (even if it is wrong). Use the Validations to catch mistakes.
declare
j pls_integer := 0;
begin
for j1 in (
select seq_id from apex_collections
where collection_name = 'MY_COLLECTION'
order by seq_id) loop
j := j+1;
--VAL1 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',

end;Clear as mud? Walk through it slowly. The syntax tells APEX which Collection (p_collection_name), then which row (p_seq), then which column/attribute (p_attr_number) to update with which value (wwv_flow.g_f0X(j)). The attribute number is the column number from the collection without the "c" in front (ie c004 in the collection = attribute 4).
The last one is your procedure to write the changes to the Database. This one should be a procedure that fires AFTER COMPUTATIONS AND VALIDATIONS. It uses that hidden KEY value to determine whether the row exists and needs to be updated, or new and needs to be inserted.
declare
begin
--Get records from Collection
for y in (select TO_NUMBER(c001) x_key, TO_NUMBER(c002) x_1,
             TO_NUMBER(c003) x_2,
             c004 x_3,
             TO_DATE(c005,'MMDDYYYY') x_dt
           FROM APEX_COLLECTIONS
           WHERE COLLECTION_NAME = 'MY_COLLECTION') loop
    if y.x_key = 0 then --New record
        insert into MY_TABLE (KEY_ID, COL1,
            COL2, COL3, COL4, COL5)
          values (SEQ_MY_TABLE.nextval, y.x_1,
              y.x_2, y.x_3, y.x_4, y.x_dt);
    elsif y.x_key > 0 then --Existing record
        update MY_TABLE set COL1=y.x_1, COL2=y.x_2,
             COL3=y.x_3, COL4=y.x_4, COL5=y.x_dt
         where KEY_ID = y.x_key;
    else
      --THROW ERROR CONDITION
    end if;
end loop;
end;Now I usually include something to distinguish the empty new rows from the full new rows, but for simplicity I'm not including it here.
Anyway, this works very well and allows me complete control over what I display on the screen and where all the data goes. I suggest using the APEX forms where you can, but for complex situations, this works nicely. Let me know if you need further clarifications.
