Dynamic Screen

Hi Gurus,
Can anyone explain how to create Screen Dynamically.
ie.,
Screen elements(checkbox, radio button, Text box) should be created based on user action. User action can be captured using pushbutton.

Dynamic screen field values

Hi,
One quick question, I have created a screen with reference to a custome table fields and it is working fine. When I enter values for the first time, the values look ok in debug but when I change the values on the screen, the new values are not updated in the screen fields in debug. Old values are shown in the debug.
I guess there is some kind of logic to do this. Like using the dynamic screen fields read or ....
Can someone help me on this?
Regards,
Roopesh Singh

hi there...
when u first enter the values, they get into the work area related to the screen fields.....
but when u change the values, they dont get changed in the workarea associated with the fields. since the data does not get updated in the fields, it wont show in the debugging mode. so chk ur code and make sure u update the data in the variables associated with the fields.
do reward if helpful or get back with further queries.

Dynamic Screen Resolution

Hello Everyone!!! I am having tough times solving query on Dynamic Screen Resolution in J2ME. How can you create an application in J2ME that automatically adjusts to the screen resolution to the phone it is being installed. That means if the resolution is small the layout automatically adjusts to the screen resolution and if its bigger then accordingly... Please help....

If you can use a UI framework/toolkit I suggest LWUIT. If not, code using proportions. Avoid absolute values of x, y, width and height. I made a sample at http://smallandadaptive.blogspot.com/2010/12/bar-chart.html

Dynamic Screen Paramater Generation

Is it possible to generate parameters for a screen on the fly??
im trying to create a generic program that can adapt selection option parameters depending on a database table.
ie if the user asks to search for an item in a table, they will be provided with a dialog containing dynamic parameters for each field in the table.
tried this using field symbols but the compiler will not let me.
ie:
for all fields in table
parameters: <pname> type <ptype>.
is it possible to generate code for a form and call it at runtime??

Yes, it is. But the statements are not released for customer use and they will not be supported by SAP. If you would like an example program, email me at my email address on my business card.   Here is another way of doing it using a POPup.

Dynamic screen update options?

We have a complex web-based user interface that is rendered using XSLT from a J2EE application. Each screen consists of lots of HTML fields, some of which are grouped together into what we call "multi-row blocks". A new block can be added by pressing a "+" button.
What our customers would like is that new blocks are added without the screen refreshing or changing. We used to have a JavaScript/Dynamic HTML solution that would do the complex HTML manipulation needed (insert new sections of HTML and re-name any fields in following blocks) but this was:
- very specific to IE 6's internals (it's manipulating how IE internally represents HTML, which can be different to the output of the original XSLT transformation);
- a couple of thousand lines of very brittle code, generally driven by regular expressions that kept breaking;
- was unacceptably slow for large screens (more than a 20-ish blocks)
To get around this we re-worked it to do a full server round-trip, using HTML Anchor tags to return the user to the start of the new block.
However, Internet Explorer has a very annoying bug that it refreshes the screen, shows the top of the form, then after a couple of seconds it then "bounces" down to the anchor position.
Does anyone know how we can get around this anchor problem? Or a better way to fix the solution, avoiding the screen refresh?
Our customers have recommended using AJAX, but that doesn't get around the problem of making a large amount of updates to the current HTML form, so would do little to help us?
Thanks,
Chris Nappin.

AJAX is really just a cadillac solution on top of your html DOM manipulation. In your case, if the client side can decide how to modify itself when the plus button is added, then ajax would just be overkill.
DOM manipulation while ugly is still probably your best bet.
AJAX, beyond what you have done already, just allows you to make server calls to get data without reloading the page. As it seems you don't need new data, ajax wouldn't help.

Dynamic Screen layout

Hi all,
I have to display fields dynamically based on certain conditions,so i started with grouping certain fields in several subscreens like this.
subscreen A
subscreen B
subscreen C
Now if for certain type of conditions i'll be displaying subscreen A and subscreen C next to that ,like subscreen C should move up to the palce of subscreen B and subscreen B will not be displayed.(so all combination of the three screens,without
any empty space inbetwen them).Wondering how to go abut that.
Is there screen flow command which calls subscreen conditionally based on 'IF' conditions and how to move screens/fields up from its original locations.
Thanks in advance,
dan.

Ok Dan, I've spent the last view minutes putting together an example, which works quite well. Here is the main program code.
REPORT zrich_001.
DATA: v_suba TYPE sy-dynnr.
DATA: v_subb TYPE sy-dynnr.
DATA: v_subc TYPE sy-dynnr.
PARAMETERS: p_suba AS CHECKBOX.
PARAMETERS: p_subb AS CHECKBOX.
PARAMETERS: p_subc AS CHECKBOX.
CALL SCREEN 100.
*&      Module PBO OUTPUT
*       text
MODULE pbo OUTPUT.
*set pf-status 'Main'.
IF p_suba = 'X'.
    v_suba = '0101'.
ENDIF.
IF p_subb = 'X'.
    IF v_suba IS INITIAL.
      v_suba = '0102'.
    ELSE.
      v_subb = '0102'.
    ENDIF.
ENDIF.
IF p_subc = 'X'.
    IF v_suba IS INITIAL.
      v_suba = '0103'.
    ELSEIF v_subb IS INITIAL.
      v_subb = '0103'.
    ELSE.
      v_subc = '0103'.
    ENDIF.
ENDIF.
IF v_suba IS INITIAL.
    v_suba = '9999'.
ENDIF.
IF v_subb IS INITIAL.
    v_subb = '9999'.
ENDIF.
IF v_subc IS INITIAL.
    v_subc = '9999'.
ENDIF.
ENDMODULE.                 " PBO OUTPUT
*&      Module pai INPUT
*       text
MODULE pai INPUT.
CASE sy-ucomm.
    WHEN 'BACK'.
      LEAVE PROGRAM.
ENDCASE.
ENDMODULE.                 " pai INPUT
Of course, you can put your own gui status and other stuff in here, but you get the idea. Here is the screen flow logic of screen 100.
PROCESS BEFORE OUTPUT.
MODULE pbo.
CALL SUBSCREEN subsa INCLUDING sy-repid v_suba.
CALL SUBSCREEN subsb INCLUDING sy-repid v_subb.
CALL SUBSCREEN subsc INCLUDING sy-repid v_subc.
PROCESS AFTER INPUT.
MODULE pai.
CALL SUBSCREEN subsa .
CALL SUBSCREEN subsb .
CALL SUBSCREEN subsc .
Now on screen 100, there are three subscreen areas, called SUBSA, SUBSB, SUBSC. Also in this program there are three subscreen dynpros, called 101, 102, and 103. So all this will need to be created to make this example work.
Now you can see in the PBO, that I am dynamically assigning the subscreen numbers to the subscreen area variables depending on what you select on the selection screen. Also, it is important to assign a dummy subscreen(with nothing in it) to any subscreen area which has not been assigned a real subscreen. So you see that I am assigning subscreen 9999 for this.
Hope this helps.

Rich Heilman

Dynamic Screen Problem

Hi,
I've created a cl_gui_container at the outter screen's initialization.Later I want to
add some something like a box into this container area, and build the content
of this box dynamicly,eg (add several box and label on it) ,how can I do it,
Thanks

Hi Ray,
Please use function RPY_DYNPRO_INSERT.
add your required UI elements in the parameter 'fields_to_containers'.
Be careful to understand the table contents before you use the function.

Dynamic Screen Programming

Hello Experts,
I want to create dynmic screen. There are multiple rows of my data.
Like for example, There is information of every subject of the student
Data line in node -> Student number,Name,Sub,Marks
Now with multiline data, if 1 student has 4 subjects, he will have 4 lines but number and name will be common
so Number and Name will come on 1 line
and 2,3,4,5 line will contain subject Name and Marks. Like this data will be generated for all students -> Student count and subject count for each student is not decided.
UI elements used will be of type, Textview,Input field,Image ,check box and Dropdown(Data is editable).
I have created all this elements using dynamic programming for a single element of node.
What I understand if I need to do the same thing for Multiple elements of node. I will need to create dynmamic node for each of element as Binding happens at node level not elmenet level.
I also tried it using table giving different UI elements for cell but here there is huge compromise on the appearance of screen.
Please advice me if there is any other way.
Thanks in advance.
Regards,
Hema

Hello Amit,
I refered the reply
Here is the code given in thread...
In one method I created the node -
IF lr_node IS BOUND.
    wd_comp_controller->lr_node = lr_node.    "Global variable
ENDIF.                                 "if lr_node is bound.
Aslo copy the table structure you crreated dynamically to global variable for later reference.
On SAVE -
FIELD-SYMBOLS :
    <lt_table>        TYPE STANDARD TABLE .
    CALL METHOD wd_comp_controller->lr_node->get_static_attributes_table
      IMPORTING
        table = <lt_table>.        "dynamic table
I am not sure when is lr_node in wd_comp_controller is created- before writing wd_comp_controller->lr_node = lr_node.
I checked the other links in the thread..but didnt help...
Can you please help me to understand ... how should I bind the dynamically created Node in the View to component controller as it needs to be accessed in different view as well..
Thank you

Dynamic screen generation

Hello everybody. I have to generate new screen and fields on it at runtime. Does anybody know how to do this?

I had implemented similar thing 6 months back.
I am giving some guideline to fulfill your requirements.
1. There will be include in your main program, say ZMAIN which will be filled by another program, say ZCONTROL.
2. You will fill include (which will contain dynamic code for your selection screen) in ZCONTROL and submit ZMAIN from ZCONTROL
REPORT ZMAIN.
include zdyn_screen. (include it in your main program)
Report ZCONTROL.
data : gt_code TYPE TABLE OF string,
wa_code type string,
c_prog type sy-repid.
wa_code = 'Parameters : test type matnr.'.
append wa_code to gt_code.
c_prog = 'ZDYN_SCREEN'.
insert report c_prog from gt_code.
commit work.
SUBMIT ZMAIN AND RETURN.
* Clear up the screen as you exit.
REFRESH GT_CODE.
READ REPORT C_PROG INTO GT_CODE.
* You may insert some check if your want OR you can omit the step of reading report
refresh gt_code.
insert report c_prog from gt_code.
Remember, you may need much more logic to handle various scenarios.
To get the text from your dictionary field for your selection screen parameters / select-options you can also use code
INSERT TEXTPOOL
To check syntax before inserting code into your include, you can try SYNTAX-CHECK or use FM EDITOR_SYTAX_CHECK.

Ganerate dynamic screens based on Table fields ? (In webDynpro)

Hi All
   Can any one explain me how to generate the screens dynamically based on the
   Table fields .
   Our requirement is some thing like based on the product fields will change then
   based on the field values screens should be generated dynamically ...
   Any help or suggestions on this will really appreciated
Adv...thanks and regards
--- prasad

Hi
   Based on the data base table fields i need to generate the screens dynamically
i.e let us take i have three products and all are having different fields but
       for buying the any products i should create the screens dynamically based
       on the chosen product and fields and for individual products.
      I shouldn't generate the screens separately for all the three products !!
      only structure i will define but based on the product and fields it should
      automatically generate the screens(which are common to all the products)
Can any one help me on this

I am rather quite new to ABAP webdynpro - one of my requirements is that based on a Custom table (so to say a custom built customizing table) I need to display fields - the Customizing table could say that for region America - we need the following fields to be supressed, the same set of fields for Japan could be Mandatory, and for Latin America could just be display only.
Is there anyway this could be acheived in Webdynpro (ABAP) - I presume that the supressed fields for America region will not be displayed but instead the common fields for America and Japan would be out of sync as far as screen layout is concerned. An ideas or guidance on how to accomplish this would be greatly appreciated.
Regards....

Hi,
you can loop on your table which gathers all the fields in it, add an attribute to your
table stating the required or not parameter and adding it to the 'state' parameter in
the new_inputfield method.
In the Wiki I added a page for dynamic UIelement creation based on DDIC properties
(wiki is down, so i don't have a link to it)
