Hi,
Thanks it is working. i Need some more help regarding this. I have set the validation on add row button. If i keep the particular field empty on which i have set the validation , and click on add row button, it clear to the complete record. value should not be clear when click on the add row button it just show the massage, Field (Active_FLG) )cannot be empty.
Thanks & Regards
VedantI am not clear; when do you trigger the validation? On submit? If yes, then it will not retain your session state values. What is the relationship between the ADD_ROW button and the validation?
FYI, if you wish to retain session state values in the tabular form, you should be writing manual tabular form using collections. You will get good amount of information on manual tabular forms and collections in this forum and outside(google).
BTW, if your question is answered, do not forget to mark the appropriate post as correct. It will help all of us in the forum.

Null Validation in Tabular Form in APEX 4.2.2

Hi to all respected Gurus of this Forum!
Recently downloaded APEX 4.2.2. As we know that this version has some improved features and one is the best is i.e. *"Validation on Tabular Form".*
For test purpose I succeeded to apply validation on field of tabular form and I am not allowed to "SUBMIT" data as per Validation Rule.
But now, I want to customize that validation as per below logic.
If required field is null than a message-box should appear with two buttons , as under:
Blank field not allowed. Do you really want to submit? (Buttons should be = YES NO)
If user press "YES" then validation should be false and record should be saved
AND
If user press "NO" then no data should be submitted/inserted as per validation logic.
Please help. Your as usual cooperation is highly appreciated in advance.

Hello Sabine,
>> I read about enhanced validation in 4.1 and would love to get rid of g_f-programming.
The major “trick” is to associate the validation/process with a Tabular Form. On the first screen of both wizards, the first field is Tabular Form. You must select the tabular form on your page (currently there can be only one. In future versions this will change).
Another factor that might influence the behavior of Tabular Form validation/process is the new attribute of Execution Scope. Unfortunately, you must enter Edit mode to gain access to this attribute (i.e., it can’t be set directly from the Tabular Form create wizard). Set it according to your need.
The rest is very simple. You should treat your Tabular Form as a simple form, where every column header stands for a form item. The following is a very simple example of validating the SAL column:
if :SAL < 1500 then
return 'Sal Value is under 1500';
else
return null;
end if;In this validation I’m using the Function Returning Error Text type.

Arie.

Add row not working when creating tabular form manually

Hi friends,
I am trying to create a manual tabular form( with the help of Denes's example). When adding a new row by clicking
the add button new row is added and i can enter data in that row. This works fine when there is only one page.
Now i have 30 rows in 2 pages. Now when i tried to add a new row by pressing the add button nothing is happening.
In my add button i have given redirect to the same page and request as ADD and the report query is as below.

Hi,
The blank row that you get from your second select statement would appear at the end of the report. Put that statement first and it should be at the top of the first page

Save changes button not working in my tabular form

Hello,
I have created a tabular form with all the button like cancel,delete,save,add row and their processes by default
when i tried to run the report, the save is not working (whenever i tried to make some changes and update the form) like it giving me an error saying that
" Error in mru internal routine: ORA-20001: no data found in tabular form "
I looked at the process MRU, it is OKAY.
I tried to delete it(the MRU process) and created a new MRU process then also the SAVE button is not working, like it gives the same error.
" Error in mru internal routine: ORA-20001: no data found in tabular form "
Can anyone help me out with this issue...!
what might be the problem?

There could be two reasons for this error:
1. in your MRU Process, you didn't type the proper primary key column name
2. your tabular form is missing the referenced collumn

Select list null value issue - for filtering the tabular form report

hello,
I have a tabular form created on emp table and in the table their are entries for the employees who don't have a location, like it is null for some of the employees.
Now I have created a select list item - for filtering the results based on location.
my select query for select list item is
select distinct location_name d,location_id r from emp order by 1
-- so my select list contains all the distinct location_name including the null on my tabular form.
so based on the selelcted value(in the select list), I am able to filter the results in my tabular form.
but the thing is that when i try to select an null value from my select list - i am not able to filter my report - like its displaying all the records, its not filtering.
can anyone help me out with this.
thanks.

Hi
Try below select for LOV
select distinct nvl(location_name,'No Location') d,nvl(location_name,'No Location') r from emp order by 1 And then change tabular from select where clause also use nvl(location_name,'No Location') like
SELECT *
FROM emp
WHERE nvl(location_name,'No Location') = :Px_YOUR_ITEMBr, Jari

Display null text field in tabular form

Seems too simple to ask in this forum but I know how to display null for a select list but how can I have a text field display blank instead of '(null)' in a tabular form?

Hi,
Go edit report attributes and check that attribute "Show Null Values as" do not have any value.

Dynamic action on tabular form

Hi all,
I'm working on a page with a tabular form. Based on the value of a radio button group, some of the columns has to be hidden. I have some experience with dynamic actions, but not in conjunction with tabular forms. I guess I have to use a jquery expression, but that's another area I don't have any experience in...
Can someone help me or give me some directions? I'm on Apex 4.1
Tom
Edited by: Tom van der Duin on 22-okt-2011 12:02

Hi there,
I am using Apex 4.0 and it seems to generate tabular forms like this:
<th id="START_DATE" class="header"> headings
<td headers="START_DATE" class="data" style=""> data cellsSo, you can use the Javascript code below to hide and show a column based on its name:
function hideShowTabularFormColumn(name, show){
if(show) {
    $("td[headers='"+name+"']").show();
    $("th.#"+name).show();
} else {
    $("td[headers='"+name+"']").hide();
    $("th.#"+name).hide();
onsomesortofevent="hideShowTabularFormColumn('START_DATE', false);"Note that, even hidden, the fields will still be submitted.

Two select lists in tabular form

I have two Select Lists which one of them depends on the another -the second one's query depends on the first one's - .....
This operation can be done in a form or a page, but how it could be done in a tabular form???
Saad

The simple answer is that to the best of my knowledge, it cannot be done because of how the tabular form works. If I understand it correctly, Tabular forms are populated completely at page load and cannot post back from items inside the form in order to refresh a list of values on the second select list. If you want to do this, you will need to build the form as a "Form and Report" page type where you have links in your report that populate a regular page form. Just tell it to put the form and the report on the same page them add a hidden page item that you set to 1 or 0 to display the form and setup the form processing so it is button tied instead of unconditional (You may have to duplicate auto processing processes).
The complex answer....there probably is a way to do this using AJAX as AJAX is good at this kind of stuff and every field in the tabular form has an HTML id of some kind....but I am not well versed enough in AJAX to give you a straight answer as to how to accomplish it. I used AJAX to do something similar to what your talking about but it was with regular page items (using a select list to populate a shuttle without a post back) and not items in a tabular form.

Problem in refreshing Tabular Form On closing Modal Page

Hi ,
          I am not able to refresh tabular form region on close of the modal page.
          can someone help me ?
Thanks and Regards,
Madonna

The fault may lie with the plugin itself. The close event is simply not being triggered. Auto-close and manual close work, but those are the only ones. The other events are not being triggered as the internal event names as defined in the plugin do not match the events triggered from the plugin javascript code.
For example, the close action of colorbox (the js plugin used in the modal page plugin to style the iframe) is bound like this:
         onClosed: function() {
            $(document).trigger('apexmodalpageclosed');
However, when you go to the plugin and edit it, and scroll down to the events section, you can see that for the close event the internal name "modalpageclose" has been filled out.
This means the event will never work with the plugin out of the box. To fix this, simply edit the internal name of the event to "apexmodelpageclosed".
The same issue exists for the open and complete events by the way, where the javascript fires an "apex..." event but the internal name does not match up.

Tabular Form Read Only Date Picker

Hello,
I have two or three Items with date pickers and do not want to implement
this code because it will be too many buttons on my form. I need to clear one item
at a time when the datepicker is readonly but, in a tabular form.
function f_clear_items()
    {$x('P1_ITEMA').value = ''};
    {$x('P1_ITEMB').value = ''};
    }Then once I create a url button and pass this function I can clear the datepicker's. But, I
was wondering is there a cleaner way to this.
I have other items on the page that are named the same but, in different tables. I only want
to clear each date picker item at a time. This code works fine for a regular form.
-Element Post Element Text for the Item to Clear
a href="javascript:setValue('P1_ITEMA','');">Clear Date</aThere is a thread named 'How to clear a read only page Item...?' that states how this code works but, does not
work for a tabular form in a Master Detail page. There is a link on side the Date Picker to clear item specified but, in a tabular form Item, there is no Element tab, any ideas on how to clear a readonly date picker item using a tabular form
and not using a button for each item, thanks in advance. I am using Application Express 3.2.0.00.27.

Dan,
I totally understand your point of view. So, this tabular form aspect was not tested once the Clear Date link was discovered to clear a Read Only date field. Yes, using a button to clear a date is great but, I do not want to clear every date or specified item with the click of one button for this application. It is very useful but, not for my needs at the moment.
Basically, if a date is selected and it needs to be cleared out you can just delete the value. But, if the date is readonly you can not clear/delete the date value unless you have the Clearing functionality for a particular item using the datepicker. It may not be worth the trouble Dan like you state by adding this extra code to the calender. If an invalid date is entered an error will appear anyway.
Thanks alot Dan for expanding my mind and showing me some JQuery and providing me with this link to do some further research if needed, thanks again.

Customer Tabular Form Questions

I am following the white paper on creating a tabular form from scratch using Html DB ver. 1.6 and having trouble getting the report to show columns as fields. In 1.6 -- There is no 'create sql report (updateable) when you are creating the page. So I had to create the page as a SQL query, then go back and change the region definition type to "SQL query - updateable report, but the rows are still not updatable. What am I missing here?
Here is my SQL:
select
htmldb_item.hidden(1,T.EMP_ID_FK) EMP_ID,
T.HOUR_TYP,
T.SUN_HR,
T.MON_HR,
T.TUE_HR,
T.WED_HR,
T.THU_HR,
T.FRI_HR,
T.SAT_HR
from #OWNER#.HR_TIMESHEET T, #OWNER#.HR_EMPLOYEE E
WHERE T.EMP_ID_FK=E.EMP_ID AND
UPPER(E.Lname) = UPPER (SUBSTR(:APP_USER,2))
Also,
I am creating this page to capture the daily hours worked based on a value entered in a different region (week ending date) -- So week ending date is not part of the tabular form report region (which is just capturing the hours worked by day (M-Sun). When they submit, it should insert the hours by day and the week ending date in the same table.
Is it possible to do this with a tabular form (created from scratch?).
Thanks,
Jeffrey

The form that is using the tabular form has columns such as hour_type (OT, Regular, Sick) and then has columns for each day. The TAble has these columns as well as a week ending date. For one week ending date, their could be 3 or more rows:
example: 1 row for hours of OT by day
1 row for Regular hours by day
1 row for Vacation hours by day
I would like to have the week ending date in a different region (that also details the employees personal information) -- and the user would select the w/end date from a date picker within this region.
This also would help by letting the employee enter the w/end date and then he/she could see their hours for that w/end date.
Thanks,
Jeff

Not null and enable or disable column in tabular form

Hi,
Using apex version 4.1 and working on tabular form.
ACT_COA_SEGMENT_MAS is Master table
and
ACT_SEGMENT_VALUES_MAS is detail table
I have entered 8 rows in master table and PARENT_SEGMENT_ID is column in master table which is null able. If i specified PARENT_SEGMENT_ID with value in master table then in detail table there is column PARENT_ID that should not be null and enable.
How i can enable or disable column when in master table PARENT_SEGMENT_ID column is null then in detail table PARENT_ID column should disable and vice versa.
I have created tabular form on Detail table. before insert into the tabular form Check in master table in first entry if PARENT_SEGMENT_ID is not null in first row of master table then in tabular form PARENT_ID should enable and not null able in corresponding to this first row id's lines in tabular form.
Same should check for second row in master table if PARENT_SEGMENT_ID is not null then entered rows with PARENT_ID into tabular form corresponding to 2nd id in master table should not nullable and column should enable in tabular form.
Thanks & Regards

Vedant,
You need to create you own manual tabular form and not use the wizard.
Using APEX_ITEM api you should be build you own form and you will be able to control how you wan to display the rows. (See Link [Apex Item Help|http://docs.oracle.com/cd/E37097_01/doc/doc.42/e35127/apex_item.htm#CACEEEJE] )
select case when PRIMARY_TABLE_COLUMN is null then APEX_ITEM.DISPLAY_AND_SAVE(3 , DETAIL_COLUMN ) else APEX_ITEM.TEXT(2,detail_column) end "ALIAS" from detail table
Hope that help.
