ALV Table column selection

Hi Experts,
Can you please help me in setting the ALV column selectable ?
I have set the column selection state at no selected at the initialization.
But when I am trying to select the column selecting the column header,. the column is not getting selected?
Am I missing something ?
Please suggest.
Thanks,
Sonia

Setting new cell variant for an alv table column

Hi,
I want to set a new cell variant for a column. Therefore I did the following steps:
1. Create an object of CL_SALV_WD_CV_STANDARD
2. SET_KEY( 'CELLVAR1 )
3. set_cell_design([..]-goodvalue_medium )
4. SET_EDITOR( lr_alv_input_field )
After that I added the cell variant to the column by using the method "add_cell_variant".
The last step is to call method SET_SELECTED_CELL_VARIANT.
I checked my program by using get_selected_cell_variant( ) and the return string was okay.
But when the table is displayed, the new cell variant isn't working. I defined an input field as the cell editor for my new cell variant but when the table is shown, it is just text - no input possible. In addition to that the selected cell design (goodvalue_medium , step 3) isn't working. So I think the cell variant is not used.
Can you help me?
Thanks & Regards,
Hendrik

Hi
I wonder if you can help me please, I too am having issues implementing ALV cell changes in WDA?
I am basically trying to dynamically change the individual color of a cell (not the entire column or row) dependant on certain criteria. I apologies but find that you are the closest resource for any potential information. Please see screen shot below.
Currently my code is as follows:
see: www.picasaweb.google.co.uk/dave.alexander69/Pictures#5244416971466907938
data: lr_cv TYPE REF TO cl_salv_wd_cv_standard.
loop at table 1 row data
 loop at table columns
 for the date columns only...
 IF <fs_column>-id(4) = 'CELL'.
 get and set column header dates from select option user input - done
 loop at table 2 row data (table 2 contains date ranges for row concerned)
 MOVE: ls_zdata-variance TO lv_variance.
 method 1 - as in sap press WD4A -:
 lr_cv = cl_wd_table_standard_cell=>new_table_standard_cell(
 view = view
 variant_key = lv_variance ).
 as mentioned...
 CREATE OBJECT lr_cv.
 lr_cv->set_key( 'VARIANCE' ).
 lr_cv->set_cell_design( '09' ).
 lr_cv->set_editor( lr_input_field ).
 lr_column->add_cell_variant( lr_cv ).
 lr_column->set_cell_editor( lr_input_field ).
 lr_column->set_sel_cell_variant_fieldname( 'VARIANCE' ).
 lr_column->set_cell_design_fieldname( value = 'COLOR_CELL' ).
 lr_field = lr_table->if_salv_wd_field_settings~get_field( <fs_column>-id ).
 lr_field->if_salv_wd_sort~set_sort_allowed( abap_false ).
 the only way I get cell coloring to work - but this is for entire column?
 ls_zdata-color_cell = cl_wd_table_standard_cell=>e_cell_design-one.
 MODIFY lt_zdata FROM ls_zdata..
 ENDLOOP.
 ENDIF.
 IF <fs_column>-id = 'COLOR_CELL'.
 CALL METHOD lr_column->set_visible( EXPORTING value = '00' ).
 ENDIF.
 ENDLOOP
 ENDLOOP.
As you see I am in the dark a bit regarding cell variants and wonder if you can point me in a better direction.
Many thanks for any help,
Dave Alexander

How to set title/text for ALV table column header in WD ABAP

Hello,
I am working in WDA using SALV_WD_Table to display data in table. I need to change the column header text, the obvious way is to get the column header and call the method SET_TEXT to set new text / title. However, this method does NOT work, it does not change the column header text. I also tried the SET_TOOLTIP, this one works, but SET_TEXT does not work. Anyone has idea why this not working and do you find any go-around solution?
My version is NW 7.0
Thank
Jayson

Hi jason ,
For setting Heder text for your ALV table
ip_confing type ref to CL_SALV_WD_CONFIG_TABLE.
"set alv table header
ip_config->if_salv_wd_table_settings~r_header->set_text( 'Test ALV Header functionality' ).
first you have to hide the DDIC text and then try to set your own text .
"modify columns
LOOP AT lt_columns INTO ls_column.
    lr_column = ls_column-r_column.
    CASE ls_column-id.
      WHEN 'MANDT'.
        "hide this field
        lr_column->set_visible( cl_wd_abstr_table_column=>e_visible-none ).
       WHEN 'SEQNR'.
        "set header to different string
        lr_column->r_header->set_ddic_binding_field( if_salv_wd_c_column_settings=>ddic_bind_none )." use this line to hide ddic text
        lr_column->r_header->set_text( 'Position' ).
    endcase.
endloop.

Web dynpro ALV table copy selected row

How to copy a selected row into new row with same values.

Hi,
I assume that there is a COPY buttonand there is a single lead seecltion for your alv table.
Now,
data:
lr_node type ref to if_wd_context_node,
lr_element type ref to if_wd_context_element,
lr_element1 type ref to if_wd_context_element,
ls_table type vbak,
ls_table1 type vbak.
lr_node = wd_context->get_chaild_node ( 'FLIGHT ' ).
if lr_node is not initial.
lr_element = lr_node->get_lead_selection ( ).
lr_elemnet1 = lr_node->get_element( index = 4). "supose the index of new row is 4
* you can use the get_element_count to know the record number
endif.
if lr_element is not initial.
lr_element->get_statitc_attributes
importing
static_attributes = ls_table
endif.
if lr_element1 is not initial.
lr_element1->set_staitc_attributes
exporting
STATIC_ATTRIBUTES = ls_table.
endif.
Assume that you have already created a new row...
use code wizard.

ALV Table columns reset!

Hello,
I have a WD application with ALV Table integrated in a view. When i run this application, and modify the settings of this table and hide some columns, this changes get saved permanently, i.e., if i relaunch the application in a new window these columns are still hidden.
How can i make sure that every time a user runs this application he gets to see all the columns no matter how he left his column settings in his earlier session. This problem exists with the standard SAP Demo ALV examples as well. And I am sure that some of you must have also faced this problem. How can i resolve this. Thanks.
Regards,
Vasu

I am not sure if there is a method to restore the default settings. But when you initialize your ALV, you can probably make each column visible explicitly. The code for doing that would be:
data: lt_col type salv_wd_t_column_ref,
ls_col type salv_wd_s_column_ref.
lt_col = l_alv_model->if_salv_wd_column_settings~get_columns( ).
loop at lt_col into ls_col.
ls_col-r_column->set_visible( abap_true ).
endloop.

Hi Praveen,
Please use the following method.

ALV Table column grouping groups

Hi All
Thank you very much in advance.
Does anyone know or have any ideas as how to dynamically add table colum groups to a WDA ALV?
Regards
~Dave Alexander

Hi Dave,
I have done that before. All you have to do is to create a dynamic context.
You need to obtain the node info of a node by calling get_node_info(). There you can add a new child node or attributes by calling the corresponding methods.
Populate this context with the dynamic internal table.
Then while creating field catalog just add all the fields you have dynamically created.
Hope this helps.
Do let me know if you have further questions.

Kinshuk

How to add button ui element in alv table data in web Dynpro ABAP

Hi Experts,
I have one requirement,

when i select that button need to display some data.
same requirement i need to devlope in alv table.
i am going to attach file please check.
Thanks in advance.
Regards,
Subba Reddy.

Hi,
You can create Button in your ALV table column with below code
DATA lo_button TYPE REF TO cl_salv_wd_uie_button.
CREATE OBJECT lo_button.
 CALL METHOD lv_value->if_salv_wd_column_settings~get_column
 EXPORTING
 id = <your column name>
 RECEIVING
 value = lo_system_select_hdr.
 lo_button->set_enabled( value = abap_true ).
 lo_button->set_text( value = 'Avaliable List' ).
 lo_button->set_tooltip( value = 'Avaliable List' ).
 lo_system_select_hdr->set_cell_editor( value = lo_button ).
And for button click action,
Create a method (say SHOW_DATA( ) ) with on_click event handler.And when you click button on your ALV table, SHOW_DATA( ) method will trigger.
Thanks

DropdownByKey inside ALV Table - Problem with Value set

Hi,
I have Component A which has a custom controller that uses the interface controller of the ALV Component.
Custom controller has node ITAB.. that has certain attributes...
I want DropdownByKey inside the ALV Table column. I am populating the corresponding attribute of ITAB node with the value set that I want the drop down to have.
However when I execute the application..I get error
" Key XXX not present in Value Set and is not initial"
XXX is present in the Value Set table of the attribute.
Following is my code in the methods of CUSTOM CONTROLLER
Generate Value Set
nodeinfo_context = wd_context->get_node_info( ).
nodeinfo_ITAB= nodeinfo_context->get_child_node( wd_this->wdctx_ITAB ).
 Populate the Value Set
data ls_valueset type wdy_key_value.
data it_valueset type wdy_key_value_table.
ls_valueset-key = 'FRA'.
ls_valueset-value = 'FRANCE'.
Append ls_valueset to it_valueset.
ls_valueset-key = 'SFO'.
ls_valueset-value = 'SAN FRANCISCO'.
Append ls_valueset to it_valueset.
Set the Value Set for the Attribute
call method nodeinfo_ITAB->SET_ATTRIBUTE_VALUE_SET
 EXPORTING
 NAME = 'ATTR1'
 VALUE_SET = it_valueset.
Changing ALV Column
Get the ALV Configuration Model
ifc_alv2 = wd_this->wd_cpifc_alv2( ).
itab_alv2_config = ifc_alv2->get_model( ).
itab_alv2_config->IF_SALV_WD_TABLE_SETTINGS~SET_READ_ONLY( abap_false ).
Get the Column reference for ATTR1
ref_alv2_colset = itab_alv2_config->if_salv_wd_column_settings~get_column( 'ATTR1' ).
Create the DropDownByKey Object
CREATE OBJECT ref_dropdownkey
 exporting SELECTED_KEY_FIELDNAME = ref_alv2_colset->id.
ref_dropdownkey->SET_SELECTED_KEY_FIELDNAME( ref_alv2_colset->id ).
ref_alv2_colset->SET_CELL_EDITOR( ref_dropdownkey ).
Check the value set
ref_attr_info = nodeinfo_flight_details2->get_attribute( ref_alv2_colset->id ).
I do get back the value set if I see ref_attr_info->value_set.
SO the Value Set is getting set for attribute ATTR1, but still I get Error
"The value selectedKey = "SFO" in DropDownByKey "_8C" does not exist in the value list and is not initial either "

You have forgotten to set a cell variant. I had the same with setting a ProgressIndicator cell-editor to a table column as default editor. This causes the column to be hidden on the table while it did show up in the settings dialog. I removed the set_editor( lr_progressindicator) and created a cell variant instead with this lr_progressindicator. You then need to add this cell variant to your column. By default it will select the standard viewtext-cell-editor (which can only be textview and inputfield, like when you create a table yourself in a view), but if you use a cell variant, it will display the required cell editor if you set it (last line of the code).
In your case, replace lr_progressindicator by your ref_dropdownkey.
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings,
 lr_column TYPE REF TO cl_salv_wd_column,
 lr_column_header TYPE REF TO cl_salv_wd_column_header,
 lr_cellvar TYPE REF TO cl_salv_wd_cv_standard,
 l_cellvar TYPE string,
 lr_progress_indicator TYPE REF TO cl_salv_wd_uie_progr_indicator.
lr_column_settings ?= wd_this->mr_table.
lr_column = lr_column_settings->get_column( 'STATUSBAR' ).
lr_column_header = lr_column->get_header( ).
lr_column_header->set_text( 'Completed' ).
CREATE OBJECT lr_cellvar.
l_cellvar = 'CV_SB'.
lr_cellvar->set_key( l_cellvar ).
CREATE OBJECT lr_progress_indicator.
lr_progress_indicator->set_percent_value_fieldname( 'STATUSBAR' ).
lr_progress_indicator->set_tooltip( 'completed' ).
lr_cellvar->set_editor( lr_progress_indicator ).
lr_column->add_cell_variant( lr_cellvar ).
lr_column->set_selected_cell_variant( l_cellvar ).
I hope this will solve your issues.

I don't think you need the f:ajax tag - you should be able to do the synchronization between the tables with the built-in partial page refresh functionality.
Just define the partialTrigger property of the second table to point to the firsttable.

Drag and drop a table column?

Hi All gurus.
Is it possible to drag a standard table as well as an ALV table column?
To re-phrase my question, I want to swap the positions of 2 columns in a table. Possible?
Thanks in adv!

You must be confusing ERP Enhancement Packages with NetWeaver Enhancement Packages. They are two completely different things. NetWeaver Enhancement Package 1 is just now in Ramp-Up. NetWeaver EnhP2 is in development and EnhP3 doesn't exist at all yet. Therefore I must assume when you say you on EHP3 you mean ERP Enhancement Package 3.

About selecting single column in a alv table.........

Hi Experts,
I need single column to be selected from a ALV table...selected in da sense to be highlighted....as it happens..by default for a row.....
I hope u understood my query...
Please help me out in this..
I know u all will surely help me...
Thks and Regards,
Runali.

Hi Runali,
Get the reference to the column settings of your ALV Model. Then you can get the reference of each column by passing the column ID. There is a method set_selected_state in the column class, but that does not highlight the column as it does for a row. So what you can use is a cell design for a column that will highlight the column with a color or whatever.
lr_column = lr_column_settings->get_column( ID = id ).
lr_column->set_cell_design( preferred design ).
Hope this helps. Please award points if it solves your purpose.

How To Edit Selected Row In ALV Table

Hello Experts,
In My Webdynpro Application, I am displaying records from database table into an ALV Table.
I want to edit only selected record from ALV table.
Please Suggest How to achieve this.
Thanks,
Pratibha

The link given above is for the UI element 'Table' and does not pertain to ALV.
To Make an ALV Editable on lead selection for that particular lead selected row.
1. The ALV should be made lead selectable, when initializing
2. The ON_LEAD_SELECT function should be invoked.
3. Withing this function the index has to be retrieved to know which row was selected.
4. Based on the index retrived all the columns have to pass FALSE to read_only in the column properties.

Pramod

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.
Best Regards,
Stephanie
