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.

Making cells of ALV/ Table readonly

Hi,
We have some requirement in project where we have to make cells of ALV/ Table as readonly dynamically depending on the data.
As per our understanding, we can define readonly property at column level. Is it possible to do such dynamic cell level operation in ALV / Table.
If someone has some demo application for the same, please help us out in this issue.
Best Regards,
Ruchi

Hi Ruchi.
This can be done by using cell variants. If you serach for ALV and cell variant(s) you will find some threads regarding this topic which might help you.

Cell Selection & ALV Table (SALV_WD_TABLE)

Hi Experts,
is it possible to select more than one cell (not row!) in an ALV Table?
I changed the cell editor to cl_salv_wd_uie_input_field and set the whole table editable.
Now I am able to select one cell, but what about multiple selections? In the Java world I found this one: TableSingleMarkableCell
Sounds good - what about ABAP?
And if there is no way with the ALV Table, how I might get the functionality with other components?
Thanks for your help, have a great week!
Hendrik
Edited by: Gedicke, Hendrik on Jul 28, 2008 11:06 AM

Hi Thomas,
I tried to integrate the cell variant TableSingleMarkableCell. But I think the ALV table does not support this cell variant, or am I wrong? The runtime class is .CL_WD_TABLE_SNGL_MARK_CELL
(see http://help.sap.com/saphelp_nw70/helpdata/EN/a5/b8fa41c915da6fe10000000a1550b0/frameset.htm)
I will try to explain:
When you want to use a cell variant, it is necessary to "add" it to a column. Therefore you can use the public method "ADD_CELL_VARIANT" of the class "CL_SALV_WD_COLUMN".
This method has got a "value" import parameter which is a referencing the class "CL_SALV_WD_CV".
The thing is that the only sub class of "CL_SALV_WD_CV" is "CL_SALV_WD_CV_STANDARD" and this means that the TableSingleMarkableCell is not supported.
Or did I made a mistake? This is my last chance to use a cell selection with the alv component.
Thanks & Regards,
Hendrik

How to set two different UIE in one cell in ALV table

Hi all,
I have a hierachy ALV table. For some reason I want to have two UI elements in one column. For example, the text and a menu next to the text. Is it possiable to do that?
best regards,
Wenwen

Hi,
thank you for your answer. Yes, now I also find the class CL_SALV_WD_MULTI_CELL_EDITOR which could be used to set different UIE in one cell. But it is quite limited, just the following UIE could be used
- LinkToAction
- LinkToURL
- FileDownload
- Button
- ToggleButton

Although it may not be exactly what you were looking for, you can create a table ColumnGroup:

Error Handling in tables using ABap Webdynpro

Hi All,
I am new to this ABAP webdynpro programming. I have a small question. I am using a table control in one of my iview. I need to check some validations on some columns of this table. Let's say I have a table with 3 columns A,B and C.
Case 1 : Whenever any user enters values in C which is greater than A i want to raise an error message saying "The Value is greater than A". The user shouldn't be allowed to enter anyother inputs before correcting the same.
OR
Case 2: If the user enters 10 rows in the table and the 5th row contains the error. How can i highlight that row or field which contains the error.
Your inputs will be valuable to me.
Regards,
Pravesh.

Hi,
Get the elements of the node for which you table is bound.
Loop through the context element set.
get the record for that context attribute and check the column A and column B value and throw
the error using the report_error_element_message when there is error.
Check this sample code -
DATA:
    lt_attr_list type STRING_TABLE,
    ls_attr_list type string.
ls_attr_list = column name.
append ls_attr_list to lt_attr_list.
clear ls_attr_list.
ls_attr_list = column name.
append ls_attr_list to lt_attr_list.
clear ls_attr_list.
DATA: lit_elementset type WDR_CONTEXT_ELEMENT_SET,
lis_element type ref to IF_WD_CONTEXT_ELEMENT,
ls_data type <<strucure type>>.
    CALL METHOD <<nodename>>->GET_ELEMENTS
      RECEIVING
        SET = lit_elementset.
    LOOP AT lit_elementsetINTO lis_element.
lis_element->get_static_atributes->
importing = ls_data.
if ls_data-columnC GT ls-data-columnA.
lr_msg_manager->report_element_error_message->
message_text = 'Column C canot be gretaer than column A'
element = lis_element
attributes = lt_attr_list <<Populate the attributes table for which errors are to be shown>>
endif.
clear: ls_data, lis_element.
ENDLOOP.

Lekha.

Select Options use in ALV Report in ABAP Webdynpro

Hello Experts,
I Already Done ALV Report In webdynpro with use of view Container UI element.But i do not know ALV report with help of select option.so
Kindly Give Me simple Example of Use in select Option In ALV.
Reply ASAP.
Regards,
Ameya Karadkhedkar

First you need to add the component WDR_SELECT_OPTIONS to the tab "Used components" of your Web Dynpro component and then also in the properties tab of your view. In the layout you need to create another view container and embed the view WND_SELECTION_SCREEN of the new used component to it.
Then in the WDDOINIT method of your view you can write this code (where SEL_OPT is the given name for the used component) in order to set the select option (This example is a select option for a date):
DATA: lo_cmp_usage           TYPE REF TO if_wd_component_usage,
      lo_interfacecontroller TYPE REF TO iwci_wdr_select_options,
      lo_r_helper_class      TYPE REF TO if_wd_select_options,
      rt_range_date          TYPE REF TO data.
* Instantiate used component WDR_SELECT_OPTIONS (SEL_OPT)
lo_cmp_usage = wd_this->wd_cpuse_sel_opt( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
lo_cmp_usage->create_component( ).
ENDIF.
* Call method in used controller
lo_interfacecontroller = wd_this->wd_cpifc_sel_opt( ).
lo_r_helper_class = lo_interfacecontroller->init_selection_screen( ).
* Create select option for the date
CALL METHOD lo_r_helper_class->create_range_table
EXPORTING
    i_typename    = 'DATS'
RECEIVING
    rt_range_table = rt_range_date.
CALL METHOD lo_r_helper_class->add_selection_field
EXPORTING
    i_id          = 'DATS'
    it_result     = rt_range_date
    i_read_only   = ABAP_FALSE.
* Hide unnecessary buttons
CALL METHOD lo_r_helper_class->set_global_options
EXPORTING
    i_display_btn_cancel = abap_false
    i_display_btn_check   = abap_false
    i_display_btn_reset   = abap_false
    i_display_btn_execute = abap_false.
Finally you need to write the following code in the action of the button in order to fetch the range table selected by the user.
DATA: lo_cmp_usage            TYPE REF TO if_wd_component_usage,
      lo_interfacecontroller TYPE REF TO iwci_wdr_select_options,
      lo_r_helper_class       TYPE REF TO if_wd_select_options,
      rt_date                 TYPE REF TO data.
FIELD-SYMBOLS: <fs_date> TYPE table.
* Instantiate used component WDR_SELECT_OPTIONS (SEL_OPT)
lo_cmp_usage = wd_this->wd_cpuse_sel_opt( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
lo_cmp_usage->create_component( ).
ENDIF.
* Call method in used controller
lo_interfacecontroller = wd_this->wd_cpifc_sel_opt( ).
lo_r_helper_class = lo_interfacecontroller->init_selection_screen( ).
* get selected range of inspections date
CALL METHOD lo_r_helper_class->get_range_table_of_sel_field
EXPORTING
    i_id          = 'DATS'
RECEIVING
    rt_range_table = rt_date.
ASSIGN rt_date->* TO <fs_date>.
Then you can use the value that is assigned to the field symbol <fs_date> to continue with your ALV.

Well, as a new member you should learn to search the forum first before posting questions. Using keywords like "jtable merge cell" will find other postings on this topic. Some with solutions some without, so you will need to read a few and decide on the approach you want to take.

Sorting issue in ALV ABAP webdynpro

Hi All,
We are displaying the data in ALV format using ABAP webdynpro.
The issue here is sorting the values. The field is the character field, as the field may contain character or numberic values.
When we sort a set of values in ascending order, the values are sorted wrongly.
Example values sorted in ascending order:
11055
11260
5662
8697
9984
The above values are sorted wrongly. Is this a standard limitation of webdynpro ABAP or do we have any support class or setting available to solve this issue.
Please help.
Regards,
Vijay

Hello Vijay
of course its not a limitation, you can sort it either ways.
Check the following link
http://help.sap.com/saphelp_nw70/helpdata/en/e9/e5eb40c4f8712ae10000000a155106/content.htm
you can use the following classes
Set sort Direction -
CL_SALV_SORTS meth: ADD_SORT (Parameter SEQUENCE)
CL_SALV_SORT meth: SET_SEQUENCE
Get sort direction
CL_SALV_SORT meth: GET_SEQUENCE
hope this helps!!
