Kindly help me out with the code.

Munna.

Hi Munna,
You can control the dynamic field hiding by using the form iterator class.
Please follow the below step to hide the field,
First create custom class with interface IF_CHTMLB_FORM_ITERATOR, then add the code in RENDER_CELL_START and constructor methods.
You need to add the below code in your .htm page
lr_form_iterator type ref to "new class name.
create object lr_form_iterator
exporting iv_context_node = BTCUSTOMERH iv_opport_h = BTOPPORTH.( these are context nodes you need to pass which are having your fields, so that you can access the fields inside the render_cell_start method)
cl_chtmlb_config=>set_iterator( lr_form_iterator ).
You need to write the code in Render_cell_start method of the new class. You need to access the context nodes to the new class and then use them to get the field1 value. If the field1 value is YES you can set empty instance to the EV_REPLACEMENT_BEE for the field2.
lv_current = gv_context_node->collection_wrapper->get_current( ). " you can set the gv_context_node in constructure method.
    IF lv_current IS BOUND.
      lv_current->get_property_as_value(
                              EXPORTING
                                iv_attr_name = 'Field1'
                              IMPORTING
                                  ev_result = lv_trailclass ).
    ENDIF.
data: lv_bee TYPE REF TO cl_bsp_bee_table.
if field1 = YES.
Case iv_bidnding_string
when 'Field2'.
create object lv_bee.
EV_REPLACEMENT_BEE = lv_bee.
endcase.
You can use the below link for more details
Change Property of the Label and Input field in UI for Form View - Part 2
For the second issue, you can achieve it by modifying the get p and Get V method of the second attribute.
let me know if you need more clarification on this.
Best Regards,

Hi Nine,
To hide select options you should use interface method REMOVE_SELECTION_SCREEN_ITEM of IF_WD_SELECT_OPTIONS.
Sample code :
Write the below code in the Event handler of Radio Button.
DATA lv_r_helper_class TYPE REF TO if_wd_select_options.
lv_r_helper_class = lo_interfacecontroller->init_selection_screen(
lv_r_helper_Class->REMOVE_SELECTION_SCREEN_ITEM(exporting i_id = 'Select_option1_id1').
This will hide first select option of your screen.Similarly pass select_option_id2 to hide it and so on.

Hi Shiva,
To get the detail about a table filed you can use DDIF* function module.
Here in this particular case you can use FM   DDIF_FIELDINFO_GET.
Pass the table name & field name.
After executing that FM you can check   DFIES_TAB in Tables parameter. i t will be having an entry.
Check for filed name as   KEYFLAG , if it is not initial ie. X then supplied filed is Primary Key.
If KEYFLAG is initial then supplied filed is not a primary key.

<PublishingWebControls:MediaFieldControl ID="MediaFieldControl1" FieldName="Article Video" runat="server"/>
All is well the video is displayed and i can add video.
My req is i need to show the video div in display mode only if video is added else it should be hidden in display mode.
how to do that?
Aruna

Hi,
According to your post, my understanding is that you want to hide the Media type field if no video uploaded.
After the video uploaded, the HTML of the Media Type Field will be changed. We can use jQuery to detect the change and hide/show it.
The following script for your reference:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
if($("selector")==""){
$("divID").hide();
</script>

How to hide information on the rtf template based on some condition

Hi,
I'm writing a new rtf template for our custom PO print program in EBS 11.5.10.. In reports 6i, you can have a format trigger on a frame or repeating frame and you can achieve this.. Can you please let me know if this is possible in XMLP and how can i do it..
Thanks,
Shree

Hi Shree,
see for example if you want to get the employees record group by department number then...in this case if you want to hide some columns of employees then use if condition...where you are using ur column name.....
like this .....if you want to hide salary column for dept no 20 then
if dept no<> 20 then sal end if;...... use this at the column def....
its like a dynamic data column generation.....for the exact code you can refer to XML Publisher User Guide......Chapter is Creating RTF Template.....section is dynamic Data Columns...

How to change the column header name dynamically based on sysdate

Post Author: senthi_gokul
CA Forum: WebIntelligence Reporting
Dear All,
i have designed some reports. i would like to change the column header dynamically based on sysdate. up to 24 months. can u help me, which add month function using the universe. i dont know if-then-else function is having the universe tool or not?

Post Author: prasingh
CA Forum: WebIntelligence Reporting
Are you saying you are not able to create an object by value (select: statement) as sysdate and put it onto the headers of your report? You can use the add_months() function on the object to add the numbers of months you wish.
Please let me knnow for more.. You can get in touch with me on [email protected] for quick reply.

Creating Files Dynamically based on Condition

Hi Experts,
I want to create a scenario in which I want to have N number of target files based on some condition.
Suppose I have following Source structure .
<ns0:MT_Employee_Src xmlns:ns0="urn://FileToFile_ERD">
   <Details>
      <EmpId>1</EmpId>
      <Name>Rabi</Name>
      <Designation>ABAP</Designation>
   </Details>
      <EmpId>4</EmpId>
      <Name>Satya</Name>
      <Designation>ABAP</Designation>
   </Details>
</ns0:MT_Employee_Src>
My requirement is I want to have 2 different target files based on EmpId.
And this should be dynamic that means N number of EmpId in my source will create N number of files.
Can anyone help me to solve this?
Any kind of suggestion will be appreciated.
Thanks
Rabi

Hi All,
As my requirement was to create N files dynamically based on some condition so I first used 1:N multimapping without BPM.
Then I followed RP's steps.
Follow those steps
1) in the message Mapping go to Signature T..Outbounded.
2)later go back to main tab . you shoud create a mapping like this:
3)<EmpId>--> change the context to MT_Employee_Src. to do that press right button on the field and go to context menu option.
map this field to the proper header target structure E.X: MT_Employee_Tgt
4) doing this you will create as many target files as <EmpId> you receive.
5) map the rest of the fields
This is great.And this helped me a lot and finally gave solution.
I want to share one thing that I faced.
when you are doing 1:N multi-mapping then you have to change the occurrence of target .
Then your source and target structure will be changed .If you are taking the source schema from mapping then remove the extra tags those got generated due to multi mapping such as
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
- <ns0:Message1>
</ns0:Message1>
</ns0:Messages>
And then use the file and it will work fine.
Thanks

How to hide a input text field in a login form.

First of all let me state i'm kind of new to AS3.
I'm making a login form, and i've managed to make it work,
but when the form actually moves frames, both the user_field, and
password_field, remains visible...
What am I missing to make those fields disappear?.
Here is my code.

thanks.

If I understood your task correctly - why not to use
object.visible = false of remove them from container?

How to hide the Form Feed char in JTextArea

We have reports (written in C) that are being displayed in a JTextArea.
In our old app, the Form Feed character (ASCII 12) was invisible naturally without having to code around it. In a JTextArea, it appears as a "[]" character. Does anyone know how to make this character invisible to the JTextArea? Removing it is not an option, as it is needed for it's print routine.
I've been searching these forums and the web all morning with no luck.

Not sure how the Form Feed character worksIt lets the printer know that a new page is to be started at that point.
Does it always appear with the New Line character?Usually but not always.
Thanks for the reply. It's more involved than just printing standard lines of text, so perhaps I should have been more clear.
The C report already has pagination built in from when it was run from our legacy GUI. In other words, each report knows how many chars wide and how many lines down each page will be. It is different for each report, but they all hover around 150 chars wide and 60 lines down per page, since they are all presented to the user (and printed) in landscape.
In the C code: at the end of each report line a "\n" is appended. At the end of each page, an ASCII 12 character is appended. A header is at the top of each page (different for each report, but usually 2 or 3 lines) that shows the page # and other info.
So, as you are viewing the report, you would see page 1 header, some report content, page 2 header, some more report content, page 3 header, etc. as you scroll down.
So now if you view it in Java: if the user wishes to print, the report is sent to our ReportPrinter class, who tokenizes the report based on "\f" and makes a ReportPage object (implements Printable) for each token. Each ReportPage is then appened to a java.awt.print.Book object, who in turn is sent to the PrinterJob.
Given that the report already has his pages figured out and has a form feed char at the end of each page, the report comes in to the JTextArea with [] chars preceding each page header (approximately every 60th line, depending on the report).
I tried using a JTextPane, but no luck. It was also much slower reading in the report. I just want the textpane to not display the non-printable characters ("\f" in this case).

How to lock a form (all fields read only) using a button (JavaScript)

Hi guys,
I have a form with several input fields, check boxes. Using a button in the form, I would like to lock it using a JavaScript. Locking means in my case that all input fields, checkboxes, etc. are read only (cannot be changed anymore).
I already use the following approach:
data.form.MyInputField.access = "readOnly";
The problem is, that this approach is not comforable from maintenance perspective. I would like a more generic or more simple way.
Generic:
loop over all fields and set them to "read only"
Simple:
xfa.form.lock; // but this does not work
Do you have any ideas how to solve this requirement in another way as I currently do?
Thanks,
Thomas

Now I used the following script:
// set the whole form as container
var objContainer = data.Report;
// call the method to set all fields to read only (recursion)
disableAllFields(objContainer);
function disableAllFields(objContainer) {
     for (var i=0; i < objContainer.nodes.length; i++) {
          switch (objContainer.nodes.item(i).className) {
               case "field" :
               case "exclGroup" :
                    objContainer.nodes.item(i).access = "readOnly";
                    break;
               case "subform" :
                    disableAllFields(objContainer.nodes.item(i));
                    break;
               default:
It works but is there another possibilitiy such like
form.lock;
Thanks,
Thomas

How to hide a report builder field if it is zero

I am using Coldfusion Report Builder. If the value of a feild is zero, how can I hide it or show a blank. Keep in mind this field is a DollarFormat() field.

When you click on the field in Report Builder, look near the bottom of the Properties window, in the "Print Control" section.
You will see an entry labelled "Print When Condition". Put an expression next to it that returns true or false.
For example, in your case, you would put something like the following:
MyField neq 0
Where "MyField" is the name of your field. This expression will only allow the field to be printed when its value is not zero.
Since you're targeting the value of the field you don't have to worry about the formatting that you used next to "Expression" in the "Data" section of the Properties window.

How to hide Interactive form in Web dynpro screen

Hi all,
I am working on an application where a user will enter the vendor number and based on that vendor the information of the vendor such as his name, address should get filled in the interactive form that we have created. I am able to get the vendor information at the back end and I have created a print button and hitting on that print button will actually fill the form. But now my problem is when I run the application the form is already displayed on the web dynpro screen (without any vlaues) and when I hit print button the form gets filled with correct values but I don;t want form to be pre displayed until and unless user hits print button. Can you please tell me how can I do this.
Thanks,
Rajat

Hi Thomas,
Thanks for quick reply.
Let me explain you what I want... I am very new to webdynpro so my questions may sound very basic or may be weird.
I have an application where the user will enter the vendor number on the web dynpro screen and then will hit the button PRINT and when he hits print button the PDF form should be displayed on the web dynpro screen. So far when I run my application the vendor number (input field) is there and a print button is also there but beneath there is the whole interactive form is showing up (a balnk) and when I enter the vendor number and hit print the same form will get filled up with the required data.
What I want is when I execute my application and on the web dynpro screen only the vendor number field and the print button should be visible and not the PDF form, the PDF form should only be displayed once user hit print button. I tried to change the value of the property from visible to none and what it did was the PDF form was not visible on the web dynpro screen on both the occassion i.e. when I execute the the web dynpro applkication and after when user hits print button.
Thanks,
Rajat
