How to keep lead selections in alv table...

Hi experts.
I made a alv.
A logic in wdmodifyview is following..
METHOD wddomodifyview .
IF first_time EQ abap_true.
wd_comp_controller->set_alv_config( ).
ENDIF.
wd_this->set_maktx( ). "<- for displaying maktx
ENDMETHOD.
When I want to select a line, do not selected.
I know because of "wd_this->set_maktx( )." sentence.
But I want to select multi lines in above condition...
How to keep selected lines in alv?
Help me please.
Thanks.
Regards.

What logic is taking place in wd_this->set_maktx( )? It is pretty difficult to say what is causing the issue without knowing what code you are executing? If you are resetting the context bound to the ALV, that would explain why you are losing your selections.

How to process Line Selection on ALV Table in ABAP WebDynpro

Hi there,
I have a view with an ALV table whose context node retrieves its data from a Service Call for a method.
The method provides certain data of a database table which the ALV displays.
Now I would like to be able to select one row of that ALV table and after pressing a button or doubleclicking on the row or whatever a different view (as for me it is also ok on the same view) should appear to display the details of that selection.
I only need to know how to retrieve the selected data.
Or its index within the internal table.
I am already looking for hours for a useful thread and actually there is one which obviously is about a similar issue apart from the multiple selection part:
How to process multiple row selection in ALV table in Wendynpro ABAP? Help!
but i am afraid that i don't understand it. Or at least I misunderstand it since it does not work with me.
The system example mentioned in the thread does not help me either because it somehow does not correspond to my needs, does it?
It would be GREAT if somebody could help me with that. Please keep it simple for I am not an expert in webdynpro yet (obviously ^^) and also please explain in detail what I have to do with the context nodes since I am not sure whether the selection is stored in my already existing node or whether I need a special one for that.
Thanks!!

Hi Christina,
If you just want to get one column data of the line that user clicked, use the Web Dynpro Code Wizard to Read Context of attibute you needed, then you will get code as follow:
* Define data for read attribute
    node_alv TYPE REF TO if_wd_context_node,
    elem_alv TYPE REF TO if_wd_context_element,
    stru_alv TYPE if_view_display=>element_alv ,
    item_column_name LIKE stru_alv-column_name.
* navigate from <CONTEXT> to <ALV> via lead selection
node_alv = wd_context->get_child_node( name = if_view_display=>wdctx_alv ).
* get element via lead selection
elem_alv = node_alv->get_element( ).
* get single attribute
elem_alv->get_attribute(
    EXPORTING
      name = `COLUMN_NAME'
    IMPORTING
      value = item_column_name ).
The value of column_name is stored in item_column_name.
If you need the index that the user clicked, try this:
* Definition of field symbol for index
FIELD-SYMBOLS : <fs_index> TYPE data.
* Get the selected index
ASSIGN r_param->index->* TO <fs_index>.
The index of clicked line is stored in field symbol <fs_index>.
Hope it will help.

Stephanie

How to do a SELECT from different tables into an internal table?

How to do a SELECT from different tables into an internal table?
I want to select data from MARA, MARC and ZPERSON and populate my ITAB_FINAL
REPORT zinternal_table.
TABLES:
mara,
marc,
zperson.
TYPES:
BEGIN OF str_table1,
v_name LIKE zperson-zname,
v_matnr LIKE marc-matnr,
v_emarc LIKE marc-emarc,
v_werks_d LIKE marc-werks_d,

v_mandt LIKE mara-mandt,
v_ernam LIKE mara-ernam,
v_laeda LIKE mara-laeda,
END OF str_table2,
itab_final LIKE STANDARD TABLE OF str_table2.

first find the link between mara , marc and zperson , if u have link to 3 tables then u can jus write a join and populate the table u want ( thats final table with all the fields).
u defenitely have alink between mara and marc so join them and retrieve all data into one internal table.
then for all the entries in that internal table retrieve data from zperson into another internal table.
then loop at one internal table
read another internal table where key equals in both the tables.
finally assign fileds if sy-subrc = 0.
gs_finaltable-matnr = gs_table-matnr
etc...
and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.

Capture multiple rows on lead select in ALV Web dynpro

Hi all,
I am trying to capture the selected rows on lead select in ALV.
I have tried with supply function and ON_LEAD_SELECT event of ALV.
When I am trying this I am able to capture only one row but not multiple.
I don't want use any extra actions or buttons to get the selected rows, it must be possible only through any ALV events or using supply function.
BR,
Eshwar

Hi,
You use this to set to on_select?
DATA:
lo_config_table TYPE REF TO cl_salv_wd_config_table.
lo_config_table->if_salv_wd_table_settings~set_on_select_enabled( ).
And in the component controller create a new method for event_handler
This method will executed
Hope this works

How to remove lead selection in table dynamically

I have a table in webdynpro which allows multiple selections of row. I have a button which is supposed to be clicked after selecting single or multiple rows. After clicking on the button I want to remove the lead selection of the selected rows (which is shown in golden color for each selected row) .
I tried REMOVE_SELECTED ELEMENTS and it works fine but only if i select the row by pressing CTRL. If i had selected a single row by just a mouse click (without ctrl) then it wont work.
THANKS

Hallo Amber,
If_wd_context_node has static attribute no_selection. use that to clear the lead_selection_index.

How to write lead selection method for a tree by nesting table column

Hi,
Follow the below steps to the solution for your problem

and type : I<your node>Element
2. Bind this action to Table property "onLeadSelec"
3. In wdModify()
     IWDTable table = (IWDTable) view.getElement("Your table id");
     table.mappingOfOnLeadSelect().addSourceMapping("nodeElement", "selectedEle");
4. In onActionLeadSelection()
     wdComponentAPI.getMessageManager().reportSuccess("Selected Item : "+selectedEle.get<Your Node Attribute>());
Let me know if you need more clarification

TreeByNestingTableColumn - how to set lead selection?

Hallo Guys!
I am using TreeByNestingTableColumn in my project. I am searching for a way to select a certain context element inside of the tree shown in such a table. I actually know that setLeadSelection doesnt work properly in such a case.
Ive already read this very helpful blog /people/valery.silaev/blog/2005/06/20/master-of-columns-part-ii searching for a solution, but its seemed not to be there.
Valery had shown how to read the selected context element recursively, but there is nothing about to how to set the needed lead selection for a certain one.
In my scenario, I am loading the whole table (10-15 elements) with only two levels of hierarchy. After the user clicks on a button I have to reload this table but keep the selection of the previously selected element.
The try using getTreeSelection didnt succeed either.
Any ideas?
Many Thanks
Dimitri
Edited by: Dmytro Lubenskyy on Apr 1, 2008 3:44 PM

Hi,
You can use the following methods to set the selection.
IWDNodeElement nodeElement = wdContext.nodeOrders().getElementAt(2);
wdContext.nodeOrders().setTreeSelection(nodeElement);

How to get one column of ALV table as dropdown by key.

Hi experts,
              How can I get one column of ALV table as dropdown and editable. If user wants to change that column value he can just select from that dropdown and click on update button. Can I provide tool tip to that column as " Select from drop down to change the status "?
Please Help.
Thanks,
Pratibha

You just need to change the cell editor of that column in ALV.
So first get access to the alv model object (adjusting the code below for your ALV Component Usage name - mine was ALV_ADV):
DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_alv_adv( ).
IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
ENDIF.
DATA l_salv_wd_table TYPE REF TO iwci_salv_wd_table.
l_salv_wd_table = wd_this->wd_cpifc_alv_adv( ).
DATA l_table TYPE REF TO cl_salv_wd_config_table.
l_table = l_salv_wd_table->get_model( ).
Then access the column object you want to change:
DATA l_column TYPE REF TO cl_salv_wd_column.
l_column = l_table->if_salv_wd_column_settings~get_column( 'REGION' ).
Then create the cell editor for DDLB and set it as the new cell editor for this column:
DATA ddlb TYPE REF TO cl_salv_wd_uie_dropdown_by_key.
create object ddlb
    exporting
      selected_key_fieldname = 'REGION'.
ddlb->set_tooltip( `Select from drop down to change the status` ).
l_column->set_cell_editor( ddlb ).

Suggestion is very much helpul for this.

How to unhide the column in Alv table

Hi Experts,
Initially i have created webdynpro Alv table with 8 columns ,later i have added one more attribute/column to the node to display extra column
but in the output ,alv table not displaying the 9th column,Instead the column is getting hidden which i came to know clicking on settings in alv table output.If i make changes in Alv table settings it getting displaying,can anyone tell me how to unhide this field.
Regards
Sandesh

Hi Sandesh,
It is possible that the user you are loggin in with, might have a layout saved.
You can try logging in with different user and see if its still hidden.
The explicit code to hide and unhide a column :
lo_alv_column->set_visible( if_wdl_core=>visibility_none ).
may be you can use the above code and make column visibility true(cahnge parameter).

Tashi
