Alternate color of tabular forms table

hi all,

Thanx
Hina

Hello,
<p>You can use a Visual Attribute in conjunction with the Set_Item_Instance_Property() built-in. Change the color of the record's item when the record number is even. Get the record number with Get_Block_Property( :system.cursor_block, CURRENT_RECORD).<br>In this article you will se how to colorize a whole record.</p>

Simple Question Alternate color for Interactive form

I can easily change the alternate color in rows for tabular but not interactive,
can someone show me how.
Thanks,
Doug

Hi,
At the moment, I don't think that's possible - see: Interactive report template
You can get the alternating colours when the page is first loaded (the above link has an example of doing that), but when you use the pagination functionality, the colours are lost.

How to prevent update in a tabular form

Hello,
I have a tabular form table based.
I need one cannot update rows, but just insert and delete.
I'm working on Apex Application Express 4.1.0.00.32.
How can i do?
Thank you.

If I get rid the Submit button, how could i submit the inserted rows?

Alternate color in Row footer

alternate color not applied in Table footer.
Can any one let me know how to acheive this?

Hi,
You can use a normal alerter for this.
A manual alerter can use a formula like Even(LineNumber()) to give a shading or not...
Then again, don't you want the footers to stand out from the body of the table?
Hope this helps,
Marianne

Color in textboxes or around textboxes in tabular form

I've got a tabular form with 12 columns of textboxes. Some of these columns are logically related so I'd like to sort of group them together a bit (the ones that are related). I was thinking about using a background color in the cells so that for example column 1-3 will have one color visible around the textbox that is displayed in the cell and column 4-5 would have another...
I've tried setting CSS STYLE under COLUMN FORMATTING to 'background-color:#CC9999;'
But that only seems to work if the cell contains text and then only the background immediately behind the text is colored, not the background of the entire cell (i think).
Is it that the textboxes take up the entire cell so that no color is visible?
If so, I'd appreciate suggestions for simple solutions... color in the textboxes? Some kind of frame around a few columns???
Thanx
Andreas

I'd suggest creating a [custom named column template|http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/themes.htm#BABFFGGJ] for the tabular form report, with logically related columns assigned to [column groups|http://www.w3.org/TR/1999/REC-html401-19991224/struct/tables.html#h-11.2.4]. When the containing table is [marked up|http://joeclark.org/book/sashay/serialization/Chapter10.html#h5-2695] in this way CSS can be used to apply colour and some other properties to the column groups/columns. It also keeps the page weight down as classes or styles don't have to be applied to every table cell.

This is a longstanding shortcoming of APEX, in that "Column Formatting" is nothing of the kind: these properties are applied to a <span> wrapped round the content rather than to the containing element (most obvious when that element is a table cell).

Tabular Form: Conditional column based on another column in table/form?

Hi!
I have 4 columns in table A:
number (the question number)
question (the question to be asked)
type (TEXT, LOV are the 2 valid values)
answer (the answer with text or a selection from the lov table below)
I have 2 columns in table B:
number (the question number)
values (a single value for the lov's)
In table B there can be mutiple rows for each number. Table A and table B
join on the number.
I want to build a tablular form on table A where for each row either a text
box or a select list is displayed depending on the contents of the type column.
So row 1 would display a text box when the type value is text; row 2 would
display a select list when the type value is lov.
Is this even possible? How do I refer to the type column in the conditional for the
answer column? I am guessing that I will need to have 2 answer columns one
that displays when the type column is TEXT and one that displays when the
type column contains LOV. This is OK. Setting up the conditional is display is the issue at this point.
Hopefully I have explained this well enough! :)
Thanks!

Hi Dave,
Sorry for not responding sooner - I finish work at 3pm GMT.
I'll take your first question first (3:28PM posting according to my display - not sure if you are on GMT time?):
As far as I understand it, using the select_list_from_query() function generates the options that are required in the select list as HTML tags. Each instance of this function should create a SELECT tag and the results of the query should generate one or more OPTION tags within it.
Second question (4:20PM posting):
The HTMLDB_ITEM functions are listed in the documentation - here's a link to the online version:
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14303/api.htm#sthref2524
Most of the examples that I have seen have been on this forum - simply search for HTMLDB_ITEM or one of its functions.
I tend to leave the generation of tabular forms to the wizard as much as possible. The only exceptions are when I need to have access to more than the Primary Key for a row but don't want to show the field on screen. There are examples on the forum about concatenating the HTMLDB_ITEM functions into a single value - this hides ID fields from the user but makes them available to PL/SQL code.
Third question (5:29PM posting)
I did try using DECODE in my questionnaire but not for the feature that you needed. Originally, I wanted to use this to display one of a number of different fields (ie, my date, number or string field as appropriate to the question) but this didn't help as I couldn't get back to the right field during the update. If you have decode working for the select lists, then that's great!
The first column should be hidden or sitting behind a checkbox as this should be the Primary Key for the row and should not be editable by the user nor would it normally be displayed.
As long as your select statement creates the correct output (albeit that you may need to work on the layout!), you should have an updatable form. However, you will need to have the MRU processes in place and the appropriate buttons that trigger these. When I did my questionnaire, I created the form using a wizard to get all of the processes and buttons and then changed the select statement. If you haven't got the processes and/or buttons, we can go through adding these onto your page.
Last question (9:08PM posting)
As explained above, column 1 should normally be hidden. The INPUT tag you detail above is what I would expect to see. The value="6" attribute indicates that 6 is the Primary Key for that row - every row will have the same tag but different values for the "value" attribute. So, if it is hidden and these are the tags you see doing a View Source on the page, then everything is correct.
OK. So now we have the data on screen and (hopefully?) we have the correct processes and buttons on the page.
The next step would be validation and update of the data.
Validation of the data can be handled by a normal page process - I can let you have example code if you want to validate the data (this will also explain how to loop through the rows - there are also methods that you can use to do this in javascript if you want). Updates should be handled by the processes and buttons on the page - again, if you haven't got these we can go through adding them in (although, if you haven't yet formatted your page, you may find it quicker to copy your select statement and create the page again using the same select statement).
ORA-20001 errors are user defined errors. Do you mean the "data has changed" errors? If so, you will probably need to include the MD5 checksum functionality (it's shown in the document linked above).
Finally, we'll keep this thread going so that you have all of your workings and my responses in one place, if that's ok with you?
Regards
Andy

Password Masking & Background Color for Multiple Rows in Tabular Form

Hi all,
I have a requirement of making a column in Tabular form, having multiple rows, masked(password field). I also want to give bg color to this field indicating that its a mandatory field.
I am unable to accomplish both at a time in my page. I am using Apex 3.2.
Waiting for your valuable comments. Thanks,
Regards,
Sandeep

APEX_ITEM API doesnot have a password function, but input fields of type password are available in HTML.
So you would have to change the field type to password in JS
That is from :
<input type="text" ...change it to
<input type="password" ...If you were using jQuery it would have been simpler, but to do it in native JS it is a bit more hard work.
Anyway here goes (a quick check in a tabular form seens to work fine)
var password_array=document.getElementsByName("f04");
for(var i=0;i<password_array.length;i++)
password_array.type = 'password';
password_array[i].style.backgroundColor = 'RED';
+Replace the "f04" with your password field's array name(use firebug to identify the field name)+
Does that solve your problem ?

Creating a manual tabular form on an empty table

Hi all,
I am trying to create a manual tabular form on an empty table. Is it possible to display textboxes and column headers, when I run the report I get "no data found".
Regards,

Hi Denes and thank you for your valuable input.
My problem is in fact that, I have created the tabular form by using a report region with a SQL query, something like,
select apex_item.display_and_save(1, p.bolge) bolge,
apex_item.display_and_save(2, p.hafta) hafta,
apex_item.display_and_save(3, p.yil) yil,
apex_item.display_and_save(4, p.mamul) mamul,
apex_item.display_and_save(5, p.tahmin1) tahmin1,
apex_item.display_and_save(6, p.tahmin2) tahmin2,
apex_item.display_and_save(7, p.tahmin3) tahmin3,
apex_item.display_and_save(8, p.tahmin4) tahmin4,
apex_item.display_and_save(9, p.tahmin5) tahmin5,
apex_item.display_and_save(10, p.tahmin6) tahmin6,
apex_item.display_and_save(11, p.revize4) revize4,
apex_item.display_and_save(12, p.revize5) revize5,
apex_item.display_and_save(13, p.revize6) revize6
from portal_link.v_planlama p
The problem is that, since there is no data in the table, when I run the page, I cant get the form to be rendered, and I get a nice "no data found". There should be a way to get the form rendered, hence making it available for data input.
Regards,
Onur

How to add a new row in Tabular Form based on a table

Hi
I have tabular form based on a table.
I want the table to have an empty row when there is no data
in the table so that I can enter data directly.
But right now whenever the page is launched, its showing a no data found message and I have to press the 'Add Row' button to enter data.
Can anyone help me out on this?
Thanks

Hi Leo
Your suggestion works fine in the APEX 2.1
But in 3.0.1 it gives this error :
Error in add row internal routine: ORA-01476: divisor is equal to zero
Error Unable to add rows.
I am not sure why this happens.

How do I Create a Tabular Form for an Intersection Table

Situation
There are three tables involved (PROJECT, STAFF, TASK)
PROJECT(PROJECT_ID, PROJECT_NAME)
STAFF(STAFF_ID, STAFF_NAME)
TASK(PROJECT_ID, STAFF_ID, HOURS)
There is a many to many relationship between PROJECT and STAFF. The intersection table is TASK.
Issue
I would like to create a tabular form for the TASK table. I would like to be able to click on a button (Add Row) to add a row to the existing tabular form. The row will have a LOV for the PROJECT_ID (showing PROJECT_NAME) and one for the STAFF_ID (showing STAFF_NAME) and a free form text field for the hours.
I've tried a bunch of different ways but am unable to acheive this functionality. I must be doing something wrong. This sort of thing is trivial.
Any guidance/suggestions are greatly appreciated.
Thanks

Adding a new surrogate key column to an existing table is not that big a deal.
alter table t add (pk int primary key);
create a before-insert row-level trigger to populate the key;Other than that, you are out of luck w.r.t the wizards. Yes, you can define a 2nd PK column in the wizard, but then the 2 PK columns becomes read-only (but you want to update them).
You can write your own tabular form using htmldb_item APIs and your own after submit processes to process the updates. See the manual Tabular Form Howto in the documentation.
Thanks

Tabular form on table with no p.k

hi all
the question i'm about to ask is basic question on creating table , and as a result of that about tabular form
i have table like this
IND NUMBER(2)
COMPANY NUMBER(5)
CLM_NUM NUMBER(15)
VERSION_NUM NUMBER(2)
DATE_GET NUMBER(8)
CAR_NUMBER VARCHAR2(7)
MISS_EXPL VARCHAR2(50)
there can be more than one row with the same data. that's why i cannot do a primary key in this table.
i want to create a tabular form on this table.
the question is as follow:
1.general question not related to tabular form.
if there is table like in my case,which i cannot see that p.k can create with the columns that i have ,do i have to add column lets say : ID which contain consistent numbers
which will be the p.k ? , or is it o.k to leave the table with no p.k.
i know that in apex 1.6 is not giving an option to create table if i'm not declare a p.k , while in 3.1 it give an
option to create with no p.k
2. second question is : if i'm not doing a primary key is it possible to create a tabular form.
i know that the tabular form ask for a p.k but i did not understand if it want the specific p.k of the table.
3. if it possible(to create tabular on table not declare with tabular form) can i have a problem in the tabular form to recognize the record(row) which need to delete or update?
4. last question: again general question about creating table
is it by the accepted to create table which has no p.k but unique constraint like this
create unique constraint IND ,COMPANY,CLM_NUM,VERSION_NUM ,DATE_GET,CAR_NUMBER?
thanks for quick response!

Hi Naama,
Firstly, a primary key does not necessarily have anything to do with the data on the table. In most of my tables, it is just a sequential value created from a sequence and set by a trigger. In some cases, I do have non-numeric primary keys, but these are simple text fields that can never contain duplicates (for example, country codes) and which the user can not alter.
So, I would strongly recommend that you create a primary key on your tables.
Secondly, yes, you can create unique constraints on those fields. But note that Apex will not allow you to use that many fields as a "primary key" on any form.
If you have records with the same values in all fields, without a primary key, Apex would not know which record was being updated.

Tabular Forms - how to change the color of text when the field is disabled

Hi,
I have a tabular form and some of it's columns are disabled showing text in grey color...
is there a way to change the color to black and bold the text...?
thanks

Okay, i've taken a look at your example.
The column formatting does not work on the input fields. The help on the item says that it generates a span with a style attribute. This would work for a display field, not for an input field.
Css like i've written should be in the style tags, put up in the header section of the page (page -> edit -> header region).
You've already put script tags there, the style tags go there aswell. You shouldn't even need to put your script tags in the header region. Just put your code up in the javascript functions region (without the script tags).
However, i tested in firefox and here color works on an input field, changing the font color. In IE it does not do this. Cross browser implementations and such, not much to do about it here. See http://stackoverflow.com/questions/602070/changing-font-colour-in-textboxes-in-ie-which-are-disabled.
I did notice that you build your form with a bunch of input fields, which you disable through javascript in the footer of the region. Then on submit, you set the disabled to false again for all those fields! If you want those fields to always be submitted to the server, why wouldn't you use the readonly attribute? Readonly fields are always submitted, and can't be edited by the user. Plus, readonly fields CAN be styled however you want! You can get rid of the javascript code in your header then.
Even the javascript in the footer is not necessary. If you just add 'readonly="true"' (without single quotes) to the element attributes of your items (edit column -> column attributes region) = no javascript at all (less maintenance).

Tabular form change color?

what if i have a tabular form and i wish to display a different background color when one of the field is displaying 'Y' instead of 'N'.
How can i do so?

Hi,
I have used your method and in fact, i placed it in the block's WHEN-NEW-RECORD-INSTANCE.If you want to set color at the time of query then you will have to use POST-QUERY on block level.
And code should be like this
BEGIN
    IF ( :product_shipping.shipment_status = 'Y' ) THEN
       Set_Item_Instance_Property('block_name.item_name', CURRENT_RECORD, Visual_Attribute, 'BCC_BG');
    else
       Set_Item_Instance_Property('block_name.item_name', CURRENT_RECORD, Visual_Attribute, '<NORMAL_ATTR>');
    END IF;
END;
and it gives me an error:
FRM-40105: Unable to resolve reference to item product_shipping
product_shipping is my block...You can not set for the block. You will have to use item by item. As you are using ITEM_INSTANCE_PROPERTY then you can not reference block in that property. If there are multiple items in that block. Then you will have to set for all items like i showed you code for single item.

Source tables for forms and tabular forms must have a primary key.

Why does HTML DB 2.0 return the message
"Source tables for forms and tabular forms must have a primary key."
when trying to generate a "Report and Form" page based on a view defined like "create view <applicationschema>.a as select * from <sourceschema>.b" ?
It should be possible for HTML DB to "see" that the table "<sourceschema>.b" already has a primary key.
bw - Christian

Christian,
In the create application wizard, when creating form or tabular form pages, you can only use tables with primary keys, and not views, because that wizard is automatically deriving the primary key from the table definition. If you want to build forms on views or tables without a primary key, you need to use one of the create form wizards while working on an existing application. Those wizards allow you to pick your own column as a primary key column.

Tabular form with non base table field

I want to develop a tabular form with
1. A non-base table edit field to accept a value
2. Insert/update another table based on the input value
3. Also, computed field on each row based on other fields on the records (like post-query trigger in oracle forms at block level - for each row)
Thanks,
Rachna

Thanks for your reply.
Varad, I like the link you sent me. It has a lot of good information.
I created a process (under page processing) called "Update/Insert Process" that dosn't seem to be working.
Question, I created a manual tabular form with SQL Query and created a process (under page processing) called "Update/Insert Process", then I check for each record in the tabular form. If the old value <> new value then I update/insert in the new table.
Any step by step will be highly apprciated - to create process/validation etc.
Thanks,
Rachna
