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

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

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.

ABAP WD: TreeByKeyTableColumn in ALV table (SALV_WD_TABLE)

Hello,
is is possible to add a TreeByKeyTableColumn object to a ALV table created
using the SALV_WD_TABLE interface?
I know that this question has already been posted several times - but the general answer ("use hierarchy columns and set_display_type( ..)") is not satisfying, since I have got the following:
The context node of cardinality 0..n which corresponds to the "column tree" to be displayed has got
- one KEY attribute
- one PARENT_KEY attribute
- one NODE_TEXT attribute
- several attributes which correspond to the table lines (respectively tree lines)
Example:
The context of cardinality 0..n has got six attributes:
KEY, PARENT_KEY, NODE_TEXT, col1 col2 col3.
During runtime, there are five "lines" in this node:
KEY    PARENT_KEY    NODE_TEXT   col1 col2 col3
1         (none)                 "node1"             a      a     a
2         1                        "node2"             b      b     b
3         2                        "node3"             c      c     c
4         1                        "node4"             d      d     d
5         (none)                 "node5"             e      e     e
The result should be in this case as if I'd have
- a table with the columns col1, col2, col3 and
- a TreeByKeyTableColumn with
     -- ROW_KEY      bound to KEY
     -- PARENT_KEY bound to PARENT_KEY
     -- containing a TextView with TEXT bound to NODE_TEXT
Result in Display:
-> node1             a   a   a                 <= Top level node
    ---> node2        b   b   b                 <= child of node with text "node1"
> node3   c   c   c                 <= child of node with text "node2"
    ---> node4        d   d   d                 <= child of node with text "node1"
-> node5            e   e   e                 <= Top level node
Can this be established with the built in hierarchy functionality of the SALV_WD_TABLE interface, too?
When playing around with the hierarchy columns functionality of SALV_WD_TABLE, I always got extra lines for the tree nodes with empty cells to the right (which I definitly don't want), and I was not able to use the parent_key<->key information already contained in the context node attributes.
But perhaps I have overlooked something?
Or is it possible to get somehow, by wild navigation through the available objects/classes/interfaces of the SALV_WD_TABLE interface, a reference to the corresponding table UI element to be able to dynamically add a TreeByKeyTableColumn with the wanted bindings?
Regards & thanks for your help

Once you have created a boolean attribute 'DAYS_READONLY' in the node bound to the DATA node of ALV, you need to set this attribute to false (for that row) if you want DAYS field to be editable when the user creates another row. In the method where you have populated the data which is being displayed make this attribute as true for those rows.
After this where you have made the ALV config settings write the following code.
DATA: lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
lr_column = lr_column_settings->get_column( 'DAYS' ).
CREATE OBJECT lr_input_field EXPORTING value_fieldname = 'DAYS'.
lr_column->set_cell_editor( lr_input_field ).
lr_input_field->set_read_only_fieldname( value = 'DAYS_READONLY' ).
CALL METHOD lr_column_settings->delete_column
    EXPORTING
      id     = 'DAYS_READONLY'
In this code you are creating input field as a cell editor and assigning it to DAYS column. After this you are setting the readonly property of the column DAYS to the value of the column 'DAYS_READONLY'. Since this column can have different values for each row, the column DAYS will be made readonly/editable accordingly. Finally you are deleting the column DAYS_READONLY from ALV output as we do not want to display its value to the user.
For more info you can refer to thread: [ALV List in the same Column for the row CELL i need button or value;

Cell selectable in table

Hi everybody,
is it possible to make a single cell selectable in a table in Web Dynpro for ABAP?
In simple ABAP it is possible and you can catch the coordinate while raising an event (button).
In Web Dynpro when I am using "input fields" instead of "text view" for the cell editor I can go into a cell, but it isn't selected.
By the way the table should not be editable ...
Thanks for all answers ...

Problem is solved.
Solution:
As described I have a context attribute "marked_cell" typed WDR_EXT_ATTRIBUTE_POINTER.
After selecting a cell my method behind the button could read the coordinates with the following code.
DATA lo_el_context    TYPE REF TO if_wd_context_element.
DATA ls_context       TYPE wd_this->element_context.
DATA lo_marked_cell   LIKE ls_context-marked_cell.
DATA lv_marked_column TYPE string.
DATA lv_marked_row    TYPE string.
* get element via lead selection
lo_el_context = wd_context->get_element( ).
* get single attribute
lo_el_context->get_attribute(
    EXPORTING
      name = `MARKED_CELL`
    IMPORTING
      value = lo_marked_cell ).
* lo_marked_cell contains direkt the column
lv_marked_column = lo_marked_cell-attribute_name.
* Additionaly we need the row number the user selected
lv_marked_row = lo_marked_cell-element->get_index( ).

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

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 keep selection (or select) the row of SORTED ALV table?

Dear Experts,
I have WD ALV table with grouped and therefore sorted layout. I know that sorted ALV beahve differently.
The problem is that if the values in cell is updated (setting attribute of selected element of context node bound to the ALV table), then the whole table is redrawn and selection disappears. It does not happen when layout of ALV is not sorted/grouped.
I need somehow to select the ALV line again. Method MOV_To of IF_WD_CONTEXT_NODE for some reason is not working in sorted ALV (it selects element on node but not in ALV table). And in ALV Interface controller I also could not find anything usefull.
Thanks.

Dmitry.

ALV Table - Different Search Help depending on Cell

Hey you experts,
For my current project I'm working on an editable ALV Table. The table has three columns and shall contain:
1) The name
2) The Old value
3) The New Value
of an item.
The name of the item is known (e.g. Product Category, Accounting Type and so on).
The main problem: I have/want to offer search-help to the user in the second and third column depending on the content of the first cell ==> The search help can of course differ in several rows. Example:
NAME         OLD-VALUE         NEW-VALUE
P.Category     Computer           Notebook
Acc.Type.       A                            B
The Computer field, shall have a search-help for a differnt data-type (DDIC help) than the A/B types.
Is this possible? There should be a kind of "On-Open-F4-Help" event in which i can adjust the F4 help, which shall be used depending on the currently selected cell.
Thanks for any help,
greetings,
Timo Stark

Hey Sam,
Yes I was able to achieve it. Create a collective search help, which includes all relevant data-elements.

     CALLCONTROL-STEP <> 'DISP'.
     EXIT.

* This step is only called for collective searchhelps. It may be used
* to reduce the amount of elementary searchhelps given in SHLP_TAB.
* The compound searchhelp is given in SHLP.
* If you do not change CALLCONTROL-STEP, the next step is the
* dialog, to select one of the elementary searchhelps.
* If you want to skip this dialog, you have to return the selected
* elementary searchhelp in SHLP and to change CALLCONTROL-STEP to
* either to 'PRESEL' or to 'SELECT'.

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.

Hi Prakash,
I have not come across this requirement till now to have context menu in a cell editor of alv.
Unfortunately the implementation of method SET_MENU of alv ui elements ( ex: cl_salv_wd_uie_text_view ) is not updating alv configurable table, instead it just stores in a global attribute as string. Hence has no effect on context menu.
If your user is very particular about this requirement of having context menu in cell editor, you can go for a normal table. Because, normal table's cell editor has the property to set the menuID as we do it for other ui elements.

Rama
