Change Inputfield to not editable

[MaG]

I want to change the status from a columnfield to not editable.

IF m_maut_row_ref->flag_ok = 'X'.

p_replacement_bee = cl_htmlb_tableviewcolumn=>factory(

columnname = 'MAUT_GEB'

edit = 'FALSE' ).

ENDIF.

but when i do this i get a white field not a grey with the value.

anyone can help ?

thx

Hi Marcel,

you want to disable the inputfield, but in fact you are just setting a parameter for the tableview column.

The "edit" parameter for the column just controls the ability of this column whether its content should be editable or not, BUT just in case the whole table row is set to edit_mode (note the parameter P_EDIT_MODE for the method render_cell_start, in case you are using an iterator).

What you want to do is - according to your problem description - to display a disabled inputfield in the column. To do so you should get familiar with tableview iterators where you can control rendering of the whole tableview, its rows, cells and contents.

See these weblogs for iterator info:

i had found a solution from an other user.

I disabled the inputfield and gave him a VALUE. Then I have a not editable inputfield with value.

But I have an other problem. Is it possible to get changes in the inputfield in a tableview, when the row is not selected ?

[maximilian_schaufler]

What do you mean by "get changes" ... you want to have an editable inputfield in a row that is not selected?

If so, than the answer is yes - using the iterator you can control the displayed elements in every way you like.

In our main web application I'm using a tableview in which I do not use the given tableview selection/edit functions, but I added some code to be able to edit non-selected lines as well.

I'm currently writing on a weblog about my tableview, might end up with several blogs, as there are quite a few non-standard things I built in there. My selection/editing solution will be included in one of these, not sure yet which one. If you have smaller additional questions, I will nevertheless help you in forum, for the "bigger picture" you gotta be patient til the weblog is done

i have a tableview with a currency inputfield. The content of this field ist 22,50. But now the user change it to 23,50 and press a button. (the line is not selected) Where can I get the new value ?

[maximilian_schaufler]

Ah, you don't know how to retrieve the values after they are submitted?

Do you use MVC or just pages with flow logic?

[MaG]

yeah thats right. where are the new value ?

i use MVC

Did you ever think of using Data Binding for your form elements? This way you don't have to care about manually retrieving the values.

If you want to access the value manually, this is how the id of the form field looks like in a tableview:

with data binding:

CONTROLLERID_MODELID_TABLENAME[ROWINDEX].COLUMNNAME

without data binding:

CONTROLLERID_TABLEVIEWID_ROWINDEX_COLUMNINDEX

[MaG]

where can i get some informations about data binding ?

Check the SAP online documentation:

hmmm here is my code to get the value of the field.

tv ?= cl_htmlb_manager=>get_data(

request = runtime->server->request

name = 'tableView'

id = 'maut' ).

IF tv IS NOT INITIAL.

tv_data = tv->data.

value = tv_data->get_cell_id(

row_index = '1'

column_index = '1' ).

• value = tv_data->get_cell_value(

• row_index = '7'

• column_index = '1' ).

*

inputfield ?= cl_htmlb_manager=>get_data(

request = request

name = 'inputField'

id = value ).

he creates me a value = maut_1_1 but it doesn't work. He doesn't get any value.

[maximilian_schaufler]

Try calling the method REQUEST->GET_FORM_FIELDS and have a look at the received values while debugging:

Here is the code to access the form fields (place in DO_HANDLE_EVENT):

data: fields type tihttpnvp.

call method request->get_form_fields_cs
  changing
    fields = fields.

This table holds all values that were received by the server on last form submit.

Check for the values there and see if this helps to identify the cause of your problem.

[MaG]

i did it, but i didn't get any changed field.

maut_AllCo<TKNUM/SND_NR/EMPF/PALL/BTGEW/GEWEI/MAUT_GEB/FLAG_OK/VBELN/

mautvisb<1214

I despair. =(

[maximilian_schaufler]

Were you able to identify to field you are having troubles with? If you don't find it in this listing then I guess we have to look at the HTML/BSP code of your page.

[MaG]

the field is maut_geb. should i post my bsp code ?

According to this entry in your fields table ...

maut_AllCo<TKNUM/SND_NR/EMPF/PALL/BTGEW/GEWEI/<b>MAUT_GEB</b>/FLAG_OK/VBELN/

...

you should receive this value - what is the content of this field when you look at it on debugging into your request?

The old value? The new/changed one? Or something different?

[MaG]

I only get a filled table. But there are only my TKNUM.

ASSIGN table_event->selectedrowindex TO <i>.
CLEAR row.
row-value1 = table_event->get_cell_value( row_index  = <i>
                                     column_index = '1' ).
row-value2 = table_event->get_cell_value( row_index  = <i>
                                     column_index = '3' ).

...
  value = request->get_form_field( name ).

Here the same problem. The request->get_form_field( name ) don't work on this server. On my developserver it works. I get the values.

when i use request->get_form_fields, then i get my changed value. But how can i get access to field ? fields-xxxx?

It is a little bit strange. request->get_form_fields work on the other server but not on my localserver. confused

Please inform us about the WebAS server version and the SP level you are running on your machines.

> The request->get_form_field( name ) don't work on this server.

What do you mean by 'dont work'?

[MaG]

WebAS on my the local developer maschine is 6.20 with SP 30

WebAS on the other Server is 6.20 with SP 43.

I mean with "don't work", that the method doesn't get any value. The value is empty.

Hi Marcel,

you should check SAP note 616900 for both servers/patchlevels. This note keeps a list of all notes for every patchlevel of WebAS.

Checking this note from time to time can save you a lot of time...

Regards,

Alex

[MaG]

thx for the list. but there are many double entries. that make the list complex.

i had debugged the methode get_form_field. I get an error number. M_LAST_ERROR = 20. Where can I found a description of this error ?

We very (very!) seldomly experience errors at the level of the HTTP request. In this case, I would seriously recommend OSS message, queue BC-CST-IC.
