How to read the selected row value of a table node

hi
i have a node of table type, displaying few records & with each record a NEXT button is there.
now i want to read the values of the selected row of the table & want to process next with NEXT button.
pls tell me how to read the values of the selected row only.
reds.

data : lo_nd type ref to if_wd_context_node,
lo_nd1 type ref to if_wd_context_node,
lt_temp type wdr_context_element_set,
wa_temp type ref to if_wd_context_element,
ls_node1 type sflight,
lt_node1 type STANDARD TABLE OF sflight.
lo_nd = wd_context->get_child_node('CN_MAIN').
CALL METHOD lo_nd->get_selected_elements
   RECEIVING
       set = lt_temp.
loop at lt_temp INTO wa_temp.
      CALL METHOD wa_temp->get_static_attributes
      IMPORTING
        static_attributes = ls_node1.
    APPEND ls_node1 TO lt_node1.
    CLEAR ls_node1.
ENDLOOP.
'CN_MAIN' is the node whose selected values are to be picked and stored in internal table lt_node1.
Other option by Thomas :
DATA lo_nd_cn_main TYPE REF TO if_wd_context_node.
DATA lt_temp TYPE wdr_context_element_set.
FIELD-SYMBOLS <wa_temp> LIKE LINE OF lt_temp.
DATA lt_node1 TYPE wd_this->elements_cn_main.
FIELD-SYMBOLS <ls_node1> LIKE LINE OF lt_node1.
lo_nd_cn_main = wd_context->get_child_node( name = wd_this->wdctx_cn_main ).
lt_temp = lo_nd_cn_main->get_selected_elements( ).
LOOP AT lt_temp ASSIGNING <wa_temp>.
    APPEND INITIAL LINE TO lt_node1 ASSIGNING <ls_node1>.
    <wa_temp>->get_static_attributes( IMPORTING STATIC_ATTRIBUTES = <ls_node1> ).
ENDLOOP.

@Max : The above hack seem to work fine unless you assign a 'DEFAULT' value to the selection fields.
@OP   : Here is an other work around, however, this approach needs an additional effort to create
    new PF-STATUS('MYLIST') and assign a function code of your choice to the function keys in the standard toolbar and handle them in the 'AT USER-COMMAND'   event as shown below. Let us know if you have/find any issues with this.
PARAMETERS:
p_test TYPE char5 DEFAULT '123'.
AT USER-COMMAND.
CASE syst-ucomm.
    WHEN 'MBACK'.
      SUBMIT zytest WITH p_test = '' VIA SELECTION-SCREEN.
ENDCASE.
START-OF-SELECTION.
SET PF-STATUS 'MYLIST'.

How to read the selected value of a dropdown list box

Hello,
I have 2 custom fields which are of type dropdown list on Accounts(CRMM_ACCOUNT) PCUI application details tab.I need to read the selected value of first dropdown list item,based on that second dropdown list will be populated.
I know where to populate the dropdown list box,it is in FILL_DROPDOWN_LISTBOX.
I dont know how to trap the selection made on dropdown list.
PLease guide me on how to trap the dropdown list field selection value.
Thanks in advance.
Thirumala.

Hello,
Check what is done in standard for the fielf REGION which is inked to the country.
Otherwise, you can do the following :
- in field group customizing, for field 1, flag the 'send request' flag. So, when you change the value in this field via the dropdown, the MAC methods are immediately called.
- Put the new value in a global variable (GV).
- in the fill_dropdown_listbox method, get the value from this GV and based on it, filter the values for the dropdown of field 2.
Hope this will help you,
Regards,
Frederic

how to check this condition

dear jayanthi,
ok if i am coding like that as u mentioned ,
it will exit the loop when first time the field value is 'R'.
if any of the selected rows contains field value 'R'. it shold not delete all the selected rows.
as u suggested it will not delete after first time the field value is r.
i am deleting it by tab index so,
suppose if i am selecting the row without field value R say its tabix is 1.
the next row with tabix 2 with field value R.
it deletes the first row and exits , it should not delete the first row also.

How to reference the selected row on a report by click a radiobox

I created a report with a column displayed as a radiobox.The report source is like "select htmldb_item.radiogroup(1,.....),rec_id,....from .... where ....",after click one radiobox,i want to get other column's value in the selected row in the after submit process ,can anyone help me?????? how to reference "rec_id" of the selected row?

Hello,
First, please tell us your first name, and update your forum handle. It’s make it easier to track your threads, and help you.
>> apex_application.g_f01(1)" only return the first record's rec_id,if i click radiobox in other rows,it returns the same result as click radiobox in the first row?
The ‘G_F01’ is an array of values, so apex_application.g_f01(1) will always bring you the first element of this array. If you want to retrieve other values from this array, which will include the values of the radiogroup value of the other lines, you need to use a loop. Something like that should work:
for i in 1.. apex_application.g_f01.count loop
… apex_application.g_f01(i) …
end loop;
>> after click one radiobox,i want to get other column's value in the selected row in the after submit process
That means that the value of your radiogroup item should include some indication to the line you are on. If, like in Andy’s example, you can retrieve your record from a table, based on a PK, your radiogroup can return this kind of information. However, if the data on the other columns of the select raw, were just entered/updated by the user (like in a tabular form), the radiogroup item should include information about the row you are in, in order for you to be able to access the corresponding array elements – other G-Fxx arrays – of the other columns in the row. In this case, I believe using checkboxes is preferable.

How to get the selected rows & columns in the table?

hi everybody,
In my application the table is kept inside the event structure.I select the cells in the table (using mouse) on running time.How to get the selected number of rows & columns in that table?

Hello,
You can fill selected values of the table by writing to it or the corresponding property using a property node - the table is just a 2D array of strings. I think for your "disable" question you are referring to the shortcut menu (when you right click). If you are using LabVIEW 8.x, you can edit or disable that shortcut menu - just right click on your table at edit time and choose Advanced >> Run-Time Shortcut Menu.

How to read the particular row in table..

HELLO ALL
I have a dynamically generated table which is filled with values
from a Bean. The next step is to select a row in that table by
clicking on a check box. The problem is that i want to read 3
values from the selected row. I can get the value from the checkbox
button but i always get the values from the first line in the
table. Is there someway to select an entire row and submit in in
the request so i can read the values from the selected row?

Yes,
but the checkbox values are printing rightly.I mean if user checks 1,5 rowed checkbox in next jsp printing 1 and 3.But the rowed values are printing sequence manner,not the chcked ones.

[UIX-ADF] How to get the selected row in my ViewObjImpl.java

Hi,
I have a uix table with a select column. I dragged my method from my ViewObjImpl
and dropped it on the select column (radiobutton) as a submitbutton.
If I run my application and select a row and press my button it always reads the first
row. Why?
I also tried including a param in my method, for the record id, but I dont know what to
pass to my action binding as a param, where can I find the selected row?
This is what I want, my method in ViewObjImpl.java
public void doDelete() {
ViewObjRowImpl pRow = (ViewObjRowImpl)this.getCurrentRow();
try {
    pRow.setIsDeleted("Y");
    //this.executeQuery();
    this.getDBTransaction().commitAndSaveChangeSet();
    //this.validate();
} catch(Exception e) { System.out.println("ERROR doDelete" + e); }
}It should set the IsDeleted field to 'Y' for the selected row. Perhaps im not doing the
right thing for this?
Can anyone give me some pointers?
Thanks in advance
Ido

Thanks. So even if you select a row and then press the button, your method still only finds the first row?!
Are you sure that the selection mechanism of your table is working? Your tableSelection fires a select event and your page contains a select handler?
When you wire your page using drag and drop the binding should always use the default iterator of the ViewObject. And getCurrentRow() should always give you the current row of that iterator. So my feeling is that the selection doesn't take place.
Or could it be that something resets the currency in the ViewObject from another place?

    IMPORTING
      e_grid = w_grid.
CALL METHOD w_grid->check_changed_data

loop at itab where mark = 'X'.

Check box als column in a standard table, how to get the selected row

Dear experts,
I habe standard tablt with check box as column. Now I want to get the current selected row structure and do some changes. How could I solve this problem? till now I just know to get the structure via lead selection.
lo_node->get_element().
lo_element = lo_node->get_static_attributes ( static_attributes = ls_row).
How could I get the element through check-box in stead of lead selection. Many thanks!

check this code
To get the selected row number
data: lr_element type ref to if_wd_context_element,
lv_index type i.
lr_element = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
lv_index = lr_element->get_index( ).
Thanks
