How to directly access a SELECTED row in a table using MasterColumn

I'm using a table with MasterColumn (TreeByNestingTableColumn) contains checkbox element.
In order to get the selected row I have to navigate the whole tree which is a very expensive when the tree is big.
I also tried without check box by just using MULTI ROW SELECTION property of the table but that didn't work.
Is there a way to directly access selected row like we do in the standrard table control?
Any help would be appretiated.

Trapping the selected row in the table using boolean checkbox

Hi,
I am using Jdev 11.1.1.2.0 with ADF 11g.
I have a screen that has a table with an additional column of 'Select boolean checkbox'. I have assigned a valuechangelistener method that helps me know which row has been selected. But the issue is it gets fired for all the rows in the table once I select/de-select a checkbox of 1 single row.
How can I handle this? Yes I can iterate through the table rows and check the values of the checkbox. But that is not I want, I also want to trap the de-select event.
What is the way to achieve this?

Timo Hahn wrote:
I don't see a bug in this behavior. This is because each row gets stamped when they render.
The way to do this is to use an attribute (which can be transient) to hold the status of the check box. Exactly this does the link I gave.
TimoHi,
Why I am saying it as a bug is because it is not firing the event for the record where the event has occurred. instead the event is fired for each row which should definitely not what is expected. And because of this we have to add an additional variable.
Now it becomes more complex if I have to handle de-selection as well, b'coz if the valuchangelistener is going to fire for all the records then I need to know which row was previously selected and now de-selected as now the de-selected record will also return a false.
So any better solution, anyone?

Passing selected rows in a table to Popup Iview

Hi all,
I have a main iview in which i search and display some data in a table. Users can select multiple rows from the table and upon clicking on a button in the table toolbar, all the selected rows should be passed to a popup iview.
But, when i tried, only one value is passed to the popup.
I need to update a set of rows together from the popup iview.
Is it a limitation of pop iviews in VC, or did i miss out anything?
I have selected "multiple select" option for the source table.
Can anyone advice us on this???
Thanks alot in advance

Hi Sreeni,
Thanks alot for your reply.
As I saw in some forum posts in SDN, multiple data rows can not be passed to a pop up.
My application has a list of submitted appointment orders which the authorized person can approve. I wanted a popup in order to provide a confirmation message when the user multi select and approve many AOs together.
I found a work around without using pop ups. Instead, I used layers to show the confirmation message. I passed the selected rows to another table using signal in and out.
It works now.
Thanks alot

How to set focus on a input field in a selected row of a table?

In a previous discussion (http://scn.sap.com/thread/3564789) I asked how to access an input (sap.m.Input) field of a selected row in a table. In the answer that was supplied I was shown how to get the items of the table. Then using the selected index to get the selected item get the cells. Then I could set editable on the proper cell(s). This worked fine.
Now I need to set the focus on one of the fields. I tried something like this:
            var oNewLink = table.getSelectedItem();
            var oNewLinkName = oNewLink.getCells()[1];
            oNewLinkName.focus();
But this doesn't seem to work.
I have searched through other discussions and have seen this technique for putting focus on a field if you have its ID:
sap.ui.getCore().byId(id_of_the_input_field).$().focus();
In my case though I do not have an ID since the row and its cells are generated. How can I set focus on the cell of a certain row in a table?

Hello Venkatesh. Yes that code does work. First I tried it on a table cell that was already rendered and it did work. The next time I tried it on a table row that was being added and it did not work there. So I added an on after rendering function for the table and added that code there. That did not work until I added a delay (timeout) to do a context switch before calling the focus and that worked.
Once last thing though sometimes when I call focus on an input field (actually in a table row cell) if the field has text in it already the flashing cursor is at the beginning of the text and other times it is at the end of the text (which is the desired way). It depends on where I click in the row. Is there anyway to make sure the flashing cursor is at the end of the text when the focus is applied to a field that contains text?

How to read attributes of selected row in table?

How can I access the selected element of a DropDownByIndex-box?

Hi,
I want to create a WebDynpro with two web services. I created the first request with the first web service and the results are displayed in a DropDownByIndex-Box. Now the user should choose one of the results and I would like to use this for the request with my second web service. How can I access the selected Element of a DropDownByIndexBox in the Code?
Thank you!!
Julia

Hi Julia,
when user select one element in drop down it automatically set lead selection of node binded to dropdown.
For example if you bind a dropdown to node myNode with value attribute myAttribute the lead selection of node myNode is set in the position of element choose from user.
So to take this chooised element use this code:
wdContext.currentMyNodeElement.getmyAttribute()

Improving performance:How to know selected rows in af:table through chk box

Hi,
I've a VO which has 3 transient variables. 2 of these transient variables getting the values from a view accessor. Using the other transient variable in the Ui to select the rows in the af:table.
In my UI, I've a table and a Check Box to select the rows. I want to get the selected rows through the check box, in the backing bean for my business requirements.
I've used below logic to get the selected rows. Here, I am iterating through the entire viewobject rows, so it is impacting the performance of the UI. How can I know the selected rows in the bean? or How can I improve the performance?
I also applied below view criteria, but still its not performant.

Hi
Please check this post [http://adfwithejb.blogspot.in/2012/08/hi-i-came-across-one-common-use-case.html].
It has clear explanation of how to provide a checkbox for selection of rows. You can also go through my comments at the end of the post. That should solve your problem of iterating through the entire VO.

How to data from selected row of a TABLE

Hi ,
I have a table displaying some PO order details. In the last column , I have a field with element Link to Action . My requirement is , that when I click on the link to action column of specific row , I want to get the data present( specifically the the data present on the first column which is PO number) i that specific row.
How can i get this data?
Regards
PG

Hi PG,
If you want to get Selected row data, you can use get_selected_elements
Try this example code.. this gives you selected records into one table..
DATA lo_nd_et_postab_1 TYPE REF TO if_wd_context_node.
DATA lo_el_et_postab_1 TYPE REF TO if_wd_context_element.
DATA ls_et_postab_1 TYPE wd_this->Element_et_postab_1.
DATA lt_et_postab_1 TYPE wd_this->Elements_et_postab_1.
DATA: wa_temp TYPE REF TO if_wd_context_element,
        lt_temp TYPE wdr_context_element_set.
navigate from <CONTEXT> to <ET_POSTAB_1> via lead selection
lo_nd_et_postab_1 = wd_context->path_get_node( path = `ZSHP_EXTENDED_DUE_LI.CHANGING_3.ET_POSTAB_1` ).
CALL METHOD lo_nd_et_postab_1->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_et_postab_1.
    append ls_et_postab_1 to lt_et_postab_1.
    CLEAR ls_et_postab_1.
ENDLOOP.
lo_nd_et_postab_1->bind_table( new_items = lt_et_postab_1 ).
NOW LT_ET_POSTAB_1 Contains selected records in table.
Hope it helps...
Cheers,
Kris.

ALV - How to set selected rows into internal table

Hi all,
I am tying to set with an 'X' flag the selected rows in my ALV using an internal table that contains all rows showed.
More exactly I have tried to follow these steps.
1) I have added the filed SEL (type SEL) to my ALV structure zrt_bo_slabsend and I defined my internal table in this way
     DATA: gt_report TYPE STANDARD TABLE OF zrt_bo_slabsend,
                gw_report TYPE zrt_bo_slabsend.
2) I have set gw_layo-box_fname = 'SEL' to gw_layo (ALV layout)
Pressing the "delete button" that I have insert on the top of the ALV, I intercept correctly my user command and I call a form (named "delete_lines") where I have this abap code
FORM delete_lines.
    DATA: l_subrc          LIKE sy-subrc,
        lw_grid_settings LIKE lvc_s_glay.
gw_layo-box_fname         = 'SEL'.
                                 "set field name to store row selection
gw_layo-edit              = 'X'. "makes whole ALV table editable
gw_layo-zebra             = 'X'.
gv_repid = sy-repid.
call function 'REUSE_ALV_GRID_DISPLAY_LVC'
exporting
      i_callback_program       = gv_repid
     i_callback_pf_status_set = gc_status
     i_callback_user_command = gc_user_command
     is_layout_lvc            = gw_layo
     it_fieldcat_lvc          = gw_fkat
     i_grid_settings          = lw_grid_settings
      i_save                   = 'X'
      is_variant               = variant
      it_events                = gt_events
    TABLES
      t_outtab                 = gt_report
    EXCEPTIONS
      program_error            = 1
      OTHERS                   = 2.
LOOP AT gt_report ASSIGNING <report> WHERE SEL = 'X'.
    DELETE gt_report.
ENDLOOP.
ENDFORM.
I'd like to select many rows in my ALV report, than by pressing the delete button I'd like to see a refresh of my ALV, without the selected rows. I want to save it only at the end of my action, only by pressing the save button.
Any suggestion about the abap code will be well appreciated.
Thanks in advance for your kind help.
Regards.

How to validate cells of selected rows in editable ALV

Hi,
I have created an ALV grid which is editable. Now I have entered the values in the grid, and selected some rows for which I need to validate the cells. But this is not happening. It is validating all the cells edited in the grid.
Can anyone help me...
Regards,
Satish Kanteti.

Hi Satish,
Follow below steps,
1. Declare a additional field for selection flag in your internal table like below,
DATA: BEGIN OF g_t_vekp OCCURS 0,
      flag(1) TYPE c,             " <------   Flag for selection
      venum TYPE vekp-venum,
      exidv TYPE vekp-exidv,
      vbeln_gen TYPE vekp-vbeln_gen,
      END OF g_t_vekp.
2. Add extra parameter 'i_callback_user_command' in FM 'REUSE_ALV_GRID_DISPLAY'.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program      = g_r_repid
      i_callback_user_command = 'USER_COMMAND'         "   <------ Additional parameter
      is_layout               = g_wa_layout
      it_fieldcat             = g_t_fieldcat[]
    TABLES
      t_outtab                = g_t_vekp
    EXCEPTIONS
      program_error           = 1
      OTHERS                  = 2.
3. Define a form 'USER_COMMAND' like below to check or save only selected rows.
FORM user_command USING l_r_ucomm LIKE sy-ucomm l_r_selfield TYPE slis_selfield.
CASE l_r_ucomm.
*Updating database when 'Save' is pressed
    WHEN '&DATA_SAVE'.
      LOOP AT g_t_vekp INTO g_wa_vekp WHERE flag = 'X'.    "   <----   Loop through only selected rows
      " Ur operation on selected records
      ENDLOOP.
ENDCASE.
l_r_selfield-refresh = 'X'.
ENDFORM.                    "user_command
Might solve ur problem.

Display and edit currently selected row of ADF Table in ADF Form

I have an ADF Read-only Table and ADF Form, which were created from the same Data Control.
I need to be able to edit the selected row of the table in the form (just like in "Binding Data Controls to your JSF page" part of "Developing RIA Web Applications with Oracle ADF" Tutorial). However, I can't figure out how to do this :(
I found the following solution on the Web: #{bindings.DeptView1.currentRow.dataProvider.dname} - but it doesn't work, since "the class oracle.jbo.server.ViewRowImpl does not have the property dataProvider".
Sorry for the newbie question.
Thanks in advance for any help!

Hi,
AFAIK, dataProvider is not supported on ADF BC, hence the error.
If you have created ADF Read only table and form from the same data control you just need to refresh the form based on table selection to show up the selected record, to do which you just need to add partialTriggers property to the panelFormLayout and set its value to the id of table

How can we pass the entire rows of a table to a web service in a VC model ?

Hi,
On the click of the submit button, I have to pass the rows of two tables into an enterprise service. This service also takes other fields of a form as an input.
How can we pass the entire rows of a table into a service ?
Regards,
Nitin

Hi Nitin,
It seems that you have two or three different structures to pass data using your webservice. In your main question, two tables, you can join both in one table and from there call the webservice. In order to pass the entire table you need:
1. Draw a line between your joinned table and your service,
2. Map the fields,
3. Create a 'SUBMIT' in your table tool bar. Right click on your table and choose 'Create Toobar', '+', name and choose 'Submit' as your event.
4. Go to Configure Element (Table View) 'Multiple' at Selection Mode.
Reward points if helps you to solve your question.

How to transpose the data records (rows) to column(lists) using apd

Hi,
how to transpose the data records (rows) to column (lists) using apd in sap bw.
I do not want to use abap routine.only use the transpose rows to list transformation .
Pls provide the step by step procedure .
thanks,
Nimai

Save youe file to transpose as a csv and in the header row of your file for the columns you want to transpose you need to put some soer of a tag before the column name (ie your colum header was for a period budget will be something lie 2011001:ZFIBDD)
1. You will need to create a new apd process (rsanwb)
2. Insert a "Read from Data File" data source object and map it file (,csv)
3. insert a transpose object into your apd process (middle row 4th one over in the transformations section)
4. under the definition tab in the transformation object select all the columns that are to be transposed into rows and move them to the transformed area, the grouping fields section should contain the rows that you want to now be columns
5.under the transformation tab enter in the seperator you selected under the Field Name/Infoobject area (ie. ZFIBDD)
6. under the details tab you need to enter in all the fields to be transformed and tner the transposition field (ie ZFIBDD)
7. Then you can insert a set of transformations and a DSO and link the newly transposed fields into that.
hope that helps

How could I insert the deleted row into another table within a trigger?

Hi,
How could I insert the deleted row into another table within a trigger? The destination table has the same columns as the source table. Since the statements are in the trigger, it is not allowed to query the source table named 'test'. Thanks! The trigger is as follows, uncompleted:

Hi,
I'm not sure what's wrong there.
I read the oracle docs about ANALYZE and ALL_TAB_COLUMNS, and did the following:
ANALYZE TABLE my_tab VALIDATE STRUCTURE; //went ok.
SELECT column_name
FROM all_tab_columns
WHERE table_name = 'my_tab'; //but no rows selected?

Get values from selected row in a Table?

Hello.
I'm on VC 7.1 (the trial version downloaded from SDN).
I'm trying to figure out a way to retrieve some values from the currently selected row in a Table element through the output connector.
I have a web-service which returns results to the Table, and I want the user to be able to select one of the rows and then trigger another web-service call with some of the values from that row -- is this possible?
Also, I can't find any documentation that lists what can and can't be done with each UI element, is there something like this some where? (the Modeler's guide doesn't help, and the Reference guide seems to focus on menu items and what the VC screen looks like)
Thanks,
Alon

Hi Alon
This is a very simple task.
You just need drag the service which you want to execute, after select row, in model.
Drag output connector from table to input connector of service. Then map the parameter.
