How to enable/disable the input fields based on the data entered/user action in the web dynpro abap?

How to enable/disable the input fields based on the data entered in the web dynpro application abap? If the user enters data in one input field then only the next input field should be enabled else it should be in disabled state. Please guide.

Hi,
Try this code.
First create a attribute with the name readonly of type wdy_boolean and bind it read_only property of input field of which is you want to enable or disable.
Next go to Init method.
Set the readonly value as 'X'.
DATA lo_el_context TYPE REF TO if_wd_context_element.
     DATA ls_context TYPE wd_this->element_context.
     DATA lv_visible TYPE wd_this->element_context-visible.
*   get element via lead selection
     lo_el_context = wd_context->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_context IS INITIAL.
     ENDIF.
*   @TODO fill attribute
*   lv_visible = 1.
*   set single attribute
     lo_el_context->set_attribute(
       name = `READONLY`
       value = 'X').
After that Go to the Action ENTER.
First read the input field ( first input field, which is value entered field) , next give a condition
if input value is not initial then set the readonly value is ' '.
DATA lo_nd_input TYPE REF TO if_wd_context_node.
     DATA lo_el_input TYPE REF TO if_wd_context_element.

*   navigate from <CONTEXT> to <INPUT> via lead selection
     lo_nd_input = wd_context->get_child_node( name = wd_this->wdctx_input ).
*   @TODO handle non existant child
*   IF lo_nd_input IS INITIAL.
*   ENDIF.
*   get element via lead selection
     lo_el_input = lo_nd_input->get_element( ).
*   @TODO handle not set lead selection
     IF lo_el_input IS INITIAL.
     ENDIF.

How to make the input field of an uplaod button to readonly

Hi all,
I have to upload an excel file using upload button.But the problem here is i want the user to use only browse button to upload a file..but he should not enter mannulally in the input field.Is it possible to gray out the input filed but the browse button should be in active state.
Regards
Padma N

Hi,
I dont think you can make the readonly only for the inputfield which is part of the FileUpload UI.
I guess your issue is related with user entering invalid urls and system hangs.

How to validate the input field data in VC using RFC FM

HI,
Could any body please give me the solution for the following issue?
When ever I enter a value in the input field of an iView, this value has to be validated from the backend BW system. Is this validation is possible using RFC function module?
If yes, please explain me.

Hi Deepak,
U can validate input fields using javascript.Write OnClientClick function for that submit button if ur using htmlb or onClick if u r using html.Refer the follows
http://help.sap.com/saphelp_nw70/helpdata/en/03/900e41a346ef6fe10000000a1550b0/frameset.htm
There are two ways to achieve ur task.
1.By checking for all alphabets.in this u need check all the alphabetic characters one by one.Refer the following
http://www.shiningstar.net/articles/articles/javascript/javascriptvalidations.asp?ID=ROLLA
http://www.shiningstar.net/articles/articles/javascript/checkNumeric.asp?ID=AW
2.By using regular expressions.its very easy and a single line code.here u need to specify single expression for whole alphabets.Refer this

How to keep the input field from PDF Form to RTF

Hi,
I'm looking to keep the input fields from my pdf form document to Rtf so I can use them in my Rtf document.
Regards,
Alan

Good day Alan,
I'm afraid that's not possible as form fields in a PDF file have no equivalent either in a Word format (.docx/.doc) or within the Rich Text Format (.rtf). That data is simply stripped during the conversion as there's no equivalent available.
Kind regards,

kindly help.
Niraja

Hi Niraja,
You can initialize the value for MATNR in the phase 1 of the eventhandler method for OVS. Try refer the code segment below. Am initializing the values for MATNR & MAKTX fields in the lines:
ls_search_input-matnr = 'D*'.
ls_search_input-maktx = '*'.

How to disabled the input parameter dialog box in crystal reports 9

Post Author: Murtaza
CA Forum: General
Hi friends,I have got stuck with a weird problem. In my
crystal report, I have set up some input parameters. I am setting
values for these parameters somewhere inside code. But I don't
want to show the default input parameter dialog box. Under any case,
user should not see the ugly parameter dialog box that crystal
presents. Please suggest me how I can achieve
this. I cannot do this through code, because our environment does
not allow that. I have to do this in crystal reports viewer and
by setting some property of the crystal report object. But everything
must be done on UI, not through code. So, the solution should not be the following.
// step before step 1
// **** the line needs to refer to the report and be set before setting
ReportSource in the viewer to myReport
myReport.EnableParameterPrompting = False
Any help would be greatly appreciated. Murtaza

Post Author: sleahcim
CA Forum: General
Hi Murtaza,
Unfortunately, I am not aware of any method to suppress the prompt for the input parameters, but still use them. It is truly a design-related issue for the report. The reason that the prompt appears is because the parameter it is prompting for is used in the report; in particular either the Group or Record Selection, or referenced in another formula.
The only way I can think of to not show the prompt, is to not use the parameter in the report. You did mention that you are setting the value of the parameter inside of the report -- are you doing this through using a formula? Perhaps you can just remove the parameter and only use the formula that you are setting the default values with.

How to Test the individualmapping field and conditions...

Hi Frnds,
I done mapping from source to destination as per tech spec in my scenario based on some conditions
i used node functions also..
But my question is how to test the every mapping filed , condition is correct or not, what i used node function working properly or not...
Regards,
Raj

Hi
If you want to check mapping for individual mapping then in design go to test tab and put your data there and then come again on Design tab and click on any target field fro which you want to check mapping then right click on target field in mpping area and click on Display queue and check whether it is expected output for that particular field mapping.

How to clear the input fields

when I click on search button, I get the search result, but along with those results, I see some input fields automatically assigned the values in the search input, which should not be.
values are assigned to these fields because of controller context field values, once the values are populated these values are assigned everywhere where istle feild referring to.
How to keep the user input without changes?
Thanks!

Naveen,
You set contradictory requirements: on one hand you have mapping, where values are always synchronized; on other hand you whant them to be unique.
Just break your existing mappings.
1. Create separate attributes in view context(s) if you do not need to access them in component controller or you do not need to be synchronized between views.
2. Create unique set of attributes in component controller for combination of attributes that really must be synchronized. Then map view context attributes accordingly.
