Disabling/greying out some values in dropdown list

Hi All -
I have a dropdown select list (LOV from a table) and it lists all the employees and contractors from a table.
How do I greyout/disable contractors only i.e. user shouldn't be able to select the contractor from the list but it should be displayed in the dropdown list.
I am using ApEx 3.2 version.
Please share your expertise.

I wasn't going to comment first, but next time search the forums before posting a question and then when it is necessary to post, please give people adequate time to respond. Oracle's forums were having technical problems which prevented me from posting earlier -- not that a 4 hour turn around is bad for free advice anyway....
My original planned response:
Patrick's response in this thread helped me:
Select List With Heading
I spiced it up a bit by actually changing the color of the option within the select list...
I added
<style>
.graySelect
color: gray;
font-size: 12px;
</style>
to the HTML Header and
modified Patrick's query by using something similar to (took my solution and put it in his example):
, JOB_ID||DECODE(JOB_ID, 'AC_MGR', '" class="graySelect" disabled="disabled') AS R
But you need to account for differences in browsers...
1) firefox (version 3 from my testing) will not let you select the disabled/grayed out option...
2) internet explorer (version 6 from my testing) WILL let you select the disabled option...it actually then sends in a NULL value for that HTTP POST parameter...so as patrick says you will need to have a page item validation to make sure they didn't submit a gray option (and return an error if they did)...
good luck!

Hi,
Expand the Attribute Period_type and double click on its GET_V method.
You will find following code line :
lr_ddlb->set_selection_table( me->job_wizard ).
Double click on the Set_selection_table method to open the method code.
You will find a LOOP.. ENDLOOP there. Here,to remove the values, comment out this LOOP- ENDLOOP.
and add following lines
         ls_ddlb-key   = 'Y'.
        ls_ddlb-value = 'Yearly'.
        APPEND ls_ddlb TO me->ddlb.
Thats All .
Hope it Helps.

How to disable (grey-out) the ticks of a JSlider?

Hi everyone,
In my GUI, I have a JSlider that I want to be disabled (greyed out)
because it should be only actived on my application next version.
(It is important though to have it to preserve GUI appearence).
Problem is that I was unable to greyout the ticks even though
already managed to grey out the slider and the number labels.
Right now, it is pretty uggly to have a partial disabled slider,
because due to ticks not being disabled.
Questions:
1) Does anyone have an idea of how to do it?
A small part of my code is shown below:
JSlider dynSl = new JSlider();
dynSl.setMajorTickSpacing(1);
dynSl.setValue(0); //Default
dynSl.setMaximum(7);
dynSl.setMinimum(0);
dynSl.setPaintLabels(true);
dynSl.setPaintTicks(true);
dynSl.setFont(new java.awt.Font("Dialog", 0, 9));
dynSl.setSnapToTicks(true);
dynSl.setEnabled(false);
// small code just to put the numbers of the slider smaller
Enumeration enum = dynSl.getLabelTable().elements();
while (enum.hasMoreElements()) {
JLabel elem = (JLabel)enum.nextElement();
elem.setFont(new Font("Dialog",0,8));
elem.setEnabled(false);
2) If not possible, how do I change the colour of a JSlider (including
the Ticks)?
My idea is to change Slider's colour to the same grey colour one used
to disable it, making at the end the slider look as if it was disabled.
Thanks in advance,
Jorge

Hi again,
Thanks for the help.
I was trying to avoid not having the ticks at all but it seems to be
the best choise because I could not solve the problem of greying out
them.
I did some more troubleshooting though and for my surprise, if I use
the same code alone, i.e, a simple frame with just the slider it works
fine. I even thought that it was related with having Windows LnF as
opposed to Metal (Java) LnF, but that was not the problem.
The only thing it comes to mind, is that there may be some problem by including the slider on a GridBagLayout !?!?!?
Anyway,
What has no simple solution, solved is! :-)

BADI/user exit for me22n - disable/grey out field quantity (MEPO1211-MENGE)

Dear all SAP gurus,
When changing PO (ME22N), I need to disable (grey out) the quantity field on item (MEPO1211-MENGE), when all scheduled quantity is already received (EKET-MENGE = EKET-WEMNG).
Have tried using LMEIGICJI and Handle_event method in CL_SCREEN_VIEW_MM. But still doesn't go to the screen that wants to be disabled.
Tried using BADI ME_PROCESS_PO_CUST, but couldn't find how to disable the quantity field.
(IF_EX_ME_PROCESS_PO_CUST~FIELDSELECTION_ITEM only works for custom field).
Please kindly advise
thanks in advance

Hi Ahmad,
No need of ABAP, follow this IMG Path.
Material Management -> Purchasing - Purchase Order -> Define Screen Layout at Document Level
After Executing it . Choose ME22 from list and then choose display icon.
than double click Quantity and Price here uncheck opt. Entry and check display.
save your work.
Hope this works.

Firstly, I still suggest you using gpresult command to check your current GP settings. Follow the steps below to generate GPReport:
1. Open CMD

How to disable (grey out) button in report

Hi,
Can any one; pls help how to disable button (grey out) on some specific condition.
I have a report of 2 pages; In first page it displays few records; once click on specific record control goes to next page 2; And here i have button (template based button); Once click on this it perform pl/sql procedure.
My requirement is: The button should disable (should not hide) when moves from page 1 to page 2 based on some specific returned values in page 2.
I have return code in button conditions (Condition type = PL/SQL Function Body Returning a Boolean)
Sample code is:
if :value1 = 'disable_test_value' then
return false;
else
return true;
end if;
The above code is working fine with button completely disappers if the :value1 = 'disable_test_value' (which is suppossed to be as we gave return false).
My question is: Is there any way; we can still show button (but button disabled or grey out; so that no action can perform on this button )? And also show some text message in other text field when button is disabled?
Thanks!!

I have an example: http://apex.oracle.com/pls/otn/f?p=27168:1 using theme #2. You need to use a theme that has a "grayed-out" alternate button template.
To accomplish this I:
1) Created one item named P1_VALUE1 to contain the condition as to whether the button should be enable ("enable_test_value") or disabled ("disable_test_value").
2) Created an enable button with a "Button Style" of "Template Based Button" with "Button Template" value of "Button". I had the "Condition" type of "PL/SQL Function Body Returning a Boolean" to be:
if :p1_value1 = 'disable_test_value' then
return false;
else
return true;
end if;I had the "URL Target" to be: javascript:alert('Performing function ...');
3) Create a disabled button with "Button Style" of "Template Based Button" with "Button Template" value of "Button, Alternate 3". I had the "Condition" type of "PL/SQL Function Body Returning a Boolean" to be:
if :p1_value1 != 'disable_test_value' then
return false;
else
return true;
end if;I had the "URL Target" to be: javascript:alert('Performing function ...');

Want to disable/"grey out" dial-up connection "settings" button in the "connections" tab of Internet Options

Hi, I'm looking to "grey out" a dial-up connection for some users in workplace, so that they are forced to use our VPN client in order to access the web. Does anyone know if this is possible?
I know you can disable all settings on that tab using local group policy, (e.g. Administrative Templates\Windows Components\Internet Explorer) but I only want to disable a specific dial-up connection (for usb 3G modems).
I've read of various IE settings being locked down in the registry here, HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restrictions, but havent seen the settings I want.
The actual connection is visible here, HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections, I just cant figure out how to grey it out. Any ideas? Thanks!

HELP - Guest Log In on File Sharing Suddenly Disabled (Grey Out)?

Hello all.
This is my office MacPro, we have a pool of Macs running graphics and also Avid software. We file share with local network through Apple File Sharing.
By default we would be able to turn on our own Mac's file sharing, and other user would log in to our Public folder > Drop Box ... etc
In Leopard, we are able to designate other folder for file share, which I have done. I disabled my default Public folder for file sharing. And created a folder outside my User folder for file sharing, so that others log into my mac as guest user can access it too.
Actually everything is just fine, other mac users just need to log in as Guest to access my share folder.
But this morning, all of a sudden, without any tweaks or anything, other mac users cannot log in as Guest, the Guest option is grey out.
I have tried disabling file share, enable, re-create a new folder to share or re-enable the default Public folder to share, but the Guest option is still grey out.
What could have happen?
Need to solve this as soon as I can, thanks and cheers

Thanks - the weekend was very pleasant indeed!
I agree that something seems to awry in the Leopard MBP. The question is "what". The symptoms now are:
1) iTunes music sharing from MBP is broken
2) Connecting to Panther Mac via AFP is broken (although one Mac can be connected via IP address)
3) Machine works well on a Windows network
Based on all of this, I would guess that there is a problem in the "Bonjour" networking of the MBP. You could try:
1. Using a different account to see if it is local to your user id.
2. Failing that, removing your com.apple.AppleFileServer.plist and com.apple.AppleShareClient.plist files from /Library/Preferences
Outside of that, I would have to do some more digging.

Value help dropdown list not showing up other values

Dear all,
I'm new to Adobe and Java WD. I managed to go through all the tutorials and developed a WDJ and embedded an interactive form in the view. I also used an RFC Model to pull some values from n R/3 table and populate in a context node element.
These values are appearing perfectly fine in the WDJ if I'm using a table or a drop down list index field.
But in the Adobe form, when i bind this context node to a WebDynpro native Value help drop down list box, only the first value of the table appears. On clicking on it, nothing happens. I'm not sure what is the problem.
Can anyone please help me in this? Should i write some code to bring the other values too? (the tutorial doesn't say this!)
If so, then please give some sample java codings and step by step process for populating the field values with the table values.
My node structure is like below
Context
     Ysam_Get_Values_Input(Node-RFC)
          Output (Node-RFC O/P)
               Values(Node-table from the RFC)
                   Slno (attribute that has the values to be populated with)
Any help is greatly appreciated.
Thanks,
Sam

How to set a default value in dropdown list in Wendynpro ABAP? Help!

Hi Experts,
       I have Webdynpro for ABAP application that shows a DropdownwithKey UI element.
1. I am able to populate the dropdown list. But by default the list is not showing any value. Only when I select a value from the list then it shows it.
So how to set the default value to the first value in the list? Any code sample will be really helpfull.
I have written the following code:
method WDDOINIT .
DATA:
    node_category TYPE REF TO if_wd_context_node_info.
node_category = WD_CONTEXT->GET_NODE_INFO( ).
node_category = node_category->GET_CHILD_NODE( 'CATEGORY' ).
data:    LT_VALUESET type WDR_CONTEXT_ATTR_VALUE_LIST,
           L_VALUE type WDR_CONTEXT_ATTR_VALUE.
L_VALUE-VALUE      = 'V1'.
L_VALUE-TEXT    = 'yesterday'.
INSERT L_VALUE into table LT_VALUESET.
L_VALUE-VALUE      = 'V2'.
L_VALUE-TEXT    = 'today'.
INSERT L_VALUE into table LT_VALUESET.
L_VALUE-VALUE      = 'V3'.
L_VALUE-TEXT    = 'tomorrow'.
INSERT L_VALUE into table LT_VALUESET.
node_category->SET_ATTRIBUTE_VALUE_SET(
             NAME = 'CAT_VALUE'
             VALUE_SET = LT_VALUESET ).
endmethod.
Note that: I am using webdynpro for ABAP.
Thanks
Gopal

I am not sure how it works in Web Dynpro for ABAP, but in Web Dynpro for Java to set default drop down value you will have to set the value for particular attribute (which is linked to the dropdown element) in the context
like
wdContext.currentContext<nodeName>Element.set<FieldName>(<defalut value>)
This generally done in Initialization method of the controller.

How to grey out the values in checkbox?

Hi,
In my library application, a "borrow book" page is available. This page displays all the books available in the library in the form of check boxes, if the available count is "0" in the database, that book will not be displayed, but ideally this is not a good apporach. I want all the books to be displayed, but the books which has the available count as "0" in the database should be greyed out, by doing this the users can see all the books available in the library, but they cannot select the "unavailable books". I have no clue, how to get this done, can someone please help me to resolve this issue.

Hi Suzi,
I would suggest not rendering a checkbox if it is not required.
Otherwise, add the attribute disabled="disabled" (this may not work in all browsers).
Regards
Michael

Tiger - All Sahring Options/Services disabled, greyed out

Hello from Portugal!
I noticed that on System Preferences I had all my Sharing services disabled and cannot select any of them (greyed out). Also, the Firewall Tab was disabled to (greyed out), and I couldn't select it either. I noticed that as the first option (also greyed out) I had a new service called "M82" ( ? ) that I had never seen before.
1- So I did a Archive and Install from Tiger 10.4.0 original DVD to try to find out what update cause this strange behavior.
2- After that I updated from 10.4.0 to 10.4.11 (Combo update) with Software Update.
3- After that I checked the Sharing services and all was well and normal. I could select/activate all the Sharing Option and the Firewall Tab was back to normal again.
4- I returned to Software Update and Made the folowing updates/instalations:
. Java 1.3.1 and 1.4.2 Release 2 (2.0)
. QuickTime (7.6)
. Migration and DVD/CD Sharing (1.1)
. Safari 3.2.1
5- After the restart I checked again and all my Sharing services and Firewall Tab were once again disabled. Also, the mysterious new service "M82" (also disabled) was back again.
So the cause of this problem is one (or more) of the updates I made in step 4 (maybe not Safari 3.2.1).
What can I do to resolve this issue without having to install Tiger 10.4.0 again?
Thank you for your help!

Thanks for your help BDAqua,
I modified my system language from Portuguese (Portugal) to english an all got back to normal.
altought it's a solution to resolve this specific problem, it's forces me t use english instead of my mother language. Not wise. I'm going to contact Apple to fix this.
Thanks again!

Sort option in Repetitive Area on AR Invoice PLD is disabled / greyed out

Hi Experts,
I have an issue whereby in my PLD the sort option under Print Layout Design Manager -> Repetitive Area -> Sort is greyed out / disabled in the AR Invoice PLD. Does anyone know why this might be? I've not seen this before and I can't find any notes relating to specifically to this issue in an AR Invoice PLD.
2007A PL06 Hot Fix 01.
Many thanks for any help,

Hello Khushwant,
In SAP when your business Process is Sales Order --> Delivery --> AR Invoice
SAP would print the Batch Numbers along with the Delivery document.
But your Business Process is Sales Order --> AR Invoice
SAP would print the Batch Numbers along with the Invoice document.
Whichever document releaves inventory, SAP will Open the Batch selection screen when adding that document and the Batch Report will be printed on a seperate sheet along with that document.
The functionality change in SBO 2007, is that the Batch number print on the Delivery / Invoice document itself instead of on a seperate Page as in 2005.
Could you please explain your Business Process in relation to what I have mentioned earlier.
Printing the Batch Number as part of the Invoice document itself in SBO 2005 is going to be a tough task.
Let me know if where and how you want to print this information.
Regards
Suda
