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.

Using a text field as well as a display as text field on a form

I have a text field that a user will enter in an employee id and from there it will populate a display as text field with their first and last name. I am trying to accomplish this using a javascript process but can not get the name to display. This does work if i change the display as text field to a select list. Can someone tell me what im doing wrong? Thanks
My code is below:

How does APEX check for null values in Text Fields on the forms?

Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
Thanks

See SQL report for LIKE SEARCH I have just explained how Select list return value works..

How to set "Display as Text" field with AJAX select list

thanks Denes for your posting. I'm trying to use the Denes Kubicek code to populate a "Display as Text" field. It works for Text Field (disabled), but not "Display as Text" field(saves state) . In my applciation I need to show this field only (not the disabled text box) when a select list value is changed. any ideas to modify the code below are appreciated.
http://htmldb.oracle.com/pls/otn/f?p=31517:80:3418128396960418::NO
here is the code from the url above
1. Create an Application Process - getDet:
DECLARE
my_det VARCHAR2 (200);
BEGIN
SELECT ename || CHR(10) || job || CHR(10) || mgr
INTO my_det
FROM emp
WHERE empno = :P80_EMPLOYEES;
HTP.prn (my_det);
END;
2. Put the following in the Region Header of your page:
<script language="JavaScript" type="text/javascript">
function f_getDet ()
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=getDet',0);
get.add('P80_EMPLOYEES',html_GetElement('P80_EMPLOYEES').value)
gReturn = get.get();
if(gReturn)
{ html_GetElement('P80_DETAILS').value = gReturn }
else
{ html_GetElement('P80_DETAILS').value = 'null' }
get = null;
</script>
3. Put the following in the HTML Form Element Attributes of :P80_EMPLOYEES:
onChange="f_getDet()";

Arie,
this works fine on normal page, except page zero. I have the AJAX select list and "Display as Text" field on page zero. The "Display as Text" field doesn't show the the value when AJAX select is changed. I'm using similar code as used in my other APEX page on OTN site. I tired to display the gReturn value, just before calling "setDisplayOnlyNode" function in the code below and it's showing correct value, but fails to display the value in the APEX field on page zero. Any ideas are appreciated.
Thanks,
Surya
<script language="JavaScript" type="text/javascript">
function setDisplayOnlyNode(pItem, pValue)
{ var textNode = pItem + '_DISPLAY'; $x(textNode).innerText = pValue; }
function f_getDet ()
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=getDet',0);
get.add('P1_EMPLOYEES',html_GetElement('P1_EMPLOYEES').value)
gReturn = get.get();
if(gReturn)
{ setDisplayOnlyNode('P1_DETAILS',gReturn)}
{ html_GetElement('P1_TEST').value = gReturn }
get = null;

Making some words Bold/Underlined of an editable text field in Adobe Form?

I have a a requirement of making some words Bold/Underlined of an editable text field in Adobe Form. I have created a "Text Field" and in "Value" tab as default value I have written the textline and made the field Type as "User entered - optional" so that at runtime user can edit that text. Now they want some words of the whole text line should display as Bold and some as Underlined. Can you please help me to meet this requirement.
Moderator message: please have a look in the dedicated forum for "Adobe Interactive Forms".
Edited by: Thomas Zloch on Feb 15, 2011 5:47 PM

Just an idea, but you might try re-printing that original PDF file to the Adobe PDF printer (saving it as another pdf file, essentially). Then try again to add form fields. (You can copy the form fields you've already created and paste them onto the new file -- just copy and paste while in forms edit mode). A second shot in the dark if the first doesn't work might be to try again, but change the print settings when printing to PDF. I've ready some reports that the dpi setting can have an effect. Maybe go from 600 to 150 and see if that works. Let me know which, if either, of these ideas works.

Is it mandatory to bind each & every CONTEXT element to a text field on the form?

Hello,
I am developing an Adobe Interactive Form, i have Designer 8.1 and Reader 9.0 in my Windows 7 Laptop. When i checked the menu EDIT-->form properties --> Compatability, its Adobe XML form File (XDP)
I have 3 elements (say, 1_Name, 2_Street and 3_City) in the CONTEXT and drawn ONLY 2 input enabled TEXT fields (for items - Name and Street of conetext) and then, BINDED them.
I did not put any associate text field for CITY and no chance of binding!
Pls. let me know that, Now can i utilize this CITY (of context) element containign data in the Java script? is this CITY is VISIBLE in the java script, even though it did not get BINDED with any text field on the form?
THank you

Thank you.
If it got BINDED, i knew how to point/get/visible the CITY element (of CONTEXT) containming data by using the below java script,
(this.rawValue == "A") or i can also get it with script of VISITOR.Page3.Subform11.CITY.rawvalue = "A"
If i do NOT bind CITY to any TEXT FIELD of FORM, then, how i can retrieve/get/visible/point CITY content?

How can we add Text field on system form which is updateable?

Hi Experts
I Want to create text field on System Form like A/R Invoice, in which I can store value after saving the document. I means Updateable field. Is it possible and How?
Thanks
Regards
Gorge

Hi Gorge,
Please follow Jeyakanthan instructions. You may know how to create a UDF but you clealy don't understant how they work.
A UDF in the System document's Title table is always updatable, unless you define it otherwise or do not have permission to update it (Open the form where you created the UDFs and press CTRL + ALT + B to open the definitions form).
A UDF in the System document's Rows table is always updatable ONLY if that document's rows are updatable AND if you set them as updatable (via Form Settings) and have permission.
On a User Form, you make your own rules!

How to display links in a text-field in Portal forms?

In a database the content in a varchar2 field could include a link:
'Shortname <a ref="#" title="Full or long item name">Long name</a>'
In a Portal report this field is displayed like:
Shortname {color:#0000ff}_Long name_
{color}
where the last part is a link. When pointing to this link with the mouse, the full item name is displayed. If this field is displayed in a Portal form, however, it is displayed exactly as written first:
Shortname <a ref="#" title="Full or long item name">Long name</a>
Could anybody tell how this field could be displayed as a link in Portal forms? The field itself does not need to be updated, it serves as an identifier for trailing fields in the details of a MD-form. If the long name should be displayed in the field, you would need to scroll horizontal to see the other details.

Yes your point is clearer now. You wish to see an abridged form of a field data with the facility to see the full data when you hover on that data. just like what we see sometimes in hyperlinks.
Both of the methods I told you work to display a modified data value* (without modifying them in the databse) and I floated them after testing. Have used slightly different functionalities in some applications a while back.
To get the 'mouse hover' display, you may want to use the java-script event-handlers of the form elements.
Both methods work with the premise that we do not want to change field data in DB; only displayed-data needs to be different.
1. The idea to edit info using sql-queries or functions from default value attribute work is the main thing. how and what should we edit the data to produce is a plsql-coding problem. So for instance, for a data example like yours, the following works!
assumption: the desired field is LINKS and is a column in PORTAL.TBL_TEST_FORMLINKS
SELECT DECODE(LINKS, NULL,NULL,SUBSTR(LINKS,INSTR(LINKS,'>','1')+1, LENGTH(LINKS)-INSTR(LINKS,'<','2'))) FROM PORTAL.TBL_TEST_FORMLINKS
If you need a different output or have a different requirement, then the example should be sufficient to guide you how to help yourself.
2. The other case of javascript embedded html in an additional plsql code also works. One such example is this:
<pre>
BEGIN
HTP.PRINT('<SCRIPT LANGUAGE="JavaScript1.1">
// find the element you want to edit first;
// hint: you may use this scheme and some basic jscript to extract the field LINKS : FORM_NAME.DEFAULT.LINKS.01
// now use javascript to get its value; treat it to fit your requirement; and equate it back to the LINKS element;
</SCRIPT>');
EXCEPTION
When Others THEN
null;
END;
</pre>
-- now follow my other instruction on FORM attributes in my second reply to see what you want to see.
these hints should be more than enough for anyone familiar with these technologies.

Link for field in tabular form

Hi everyone,
How can you create add a link (which opens a pop up screen) next to a field in a tabular form, in order to set the value in that field with the value
selected in the pop up screen.
I already know how to set the values.
In the tabular form when you add a link, you see the id and row also. How can I remove that or is there another way to set the values.
Thanks,
Cleo

I think you can accomplish what you want by changing the the field to update from text to a popup lov. You can do this by going into the report attributes of the tabular form and then clicking the pencil next to the field who needs the lookup values. Change the 'display as' box from text to popup lov and supply the values.
You can also hide fields by going into the report attributes and unchecking Show.
There is an overview of some concepts here http://download.oracle.com/docs/cd/E14373_01/appdev.32/e13363/frm_tabular.htm.
Let me know if I'm not understanding your post correctly.

Display as Text field won't populate from select

I'm an Oracle Forms person trying to learn APEX. Love it but having problems with seemingly simple stuff. I made a simple page exactly from sample code found from Oracle documentation and still can't get to work. Appreciate any help.
Have simple form with 2 fields. One field P400_DEPTNO which is select field. Code in the HTML Form Element Attributes: onchange="javascript:getDNAME(this);"
The other field is D400_DNAME which have as Display as Text(escape special characters, does not save state)
I have application item G_DEPTNO
application process GET_DNAME:
DECLARE
vDNAME VARCHAR2(100);
BEGIN
SELECT DNAME INTO vDNAME FROM DEPT WHERE DEPTNO = :G_DEPTNO;
htp.p(vDNAME);
EXCEPTION WHEN OTHERS THEN
htp.p('No such department!');
END;
code in HTML Header of page 400:
<script type="text/javascript">
function getDNAME(filter)
var get = new htmldb_Get(null,&APP_ID.,'APPLICATION_PROCESS=GET_DNAME',0);
get.add('G_DEPTNO', filter.value);
var ret = get.get();
if(ret)
var d = document.getElementById("P400_DNAME");
d.innerHTML = ret;
get = null;
</script>
I'm getting this error when running page:
get error:
Line: 25
Char: 3
Error: 'null' is null or not an object
when I view source: line 25 is:
d.innerHTML = ret;
I have tried so many variations. Could something on my system not be installed correctly or am I just missing something simple? Appreciate any help offered.

Cascading Text Boxes in Tabular Form

Hello Gurus,
I have a Cascading Select List in a Tabular Form made with APEX_ITEM.
My Tabular Form is like this: Col1[select list], Col2[select list], Col3, col4 .
Now :- I would like Col2 to be made as a TEXT BOX as opposed to SELECT LIST. But this TEXT BOX should still be populated "On Change" of Col1 and the TEXTBOX should be editable.
I saw another function called: TEXT_FROM_LOV_QUERY but I can not set the item_id [to use in HTML HEAD Java Script Function & Application Process] as the signature of the function does not support.
APEX_ITEM.TEXT_FROM_LOV_QUERY (
    p_value       IN    VARCHAR2 DEFAULT NULL,
    p_query       IN    VARCHAR2,
    p_null_text   IN    VARCHAR2 DEFAULT '%')
    RETURN VARCHAR2;Please point me to any relevant examples.
Appreciate any help in this regard. Please let me know if I could not explain my problem well.

How to create a group/list of check box variables for display in text field, in appended format

I need to identify a series of single-response checkbox variables and display the ones selected (as a group) in a text field in an appended (comma, space) format. Last week, you provided a great little script for a similar need using List Box (multiple response) variables. This time I need to know how to formally identify the checkbox variables and, I presume, use a similar script to display the results in a comma, space format.
You've been of great help.
Thanks

Here's the script adapted to this situation. It assumes there are ten check boxes named cb1, cb1, cb2, ...cb10.
// Custom Calculate script for text field
(function () {
    // Initialize the string
    var v, s = "";
    // Loop through the check boxes to build up a string
    for (var i = 1; i < 11; i++) {
        // Get the value of the current check box
        v = getField("cb" + i).value;
        if (v !== "Off") {
            if (s) s += ", "; // Add a comma and a space if needed
            s += v; // Add the selected value
    // Set this field value to the string
    event.value = s;
You'll have to change the field name and starting/ending numbers to match your form.

How to display a text field if yes selected in radio button

Does anyone know how to hide/show a text field based upon a
radio button selection? What I want to do is ask a question with
yes or no as radio buttons. Then, if the user selects "YES" I want
to display a required text field. If the user click no, there isn't
a need for the text field.

Try this...
<html>
<head>
</head>
<script>
function ShowField(){document.MyForm.MyField.style.display =
"inline";}
</script>
<body>
<form name="MyForm">
<input type="radio" name="MyCheckBox"
onClick="ShowField()">
<input type="text" style="display: none"
name="MyField">
</form>
</body>
