How to detect a selected row in ALV GRID

Hi,
Can anyone tell me how to detect and catch an event when a row is selected in an ALV GRID?
I would like to catch such event when the end user presses Ctrl + Shif + Space bar.
Thank you and best regards.
Hassane.

Hi,
Use this wiki link, to have a checkbox with all the records in ALV Grid and to process those selected records at a user command, as per the requirement.

Hope this solves your problem.
Thanks & Regards,

How to find the selected item in alv grid or table control

can any one tell me please
how to find the selected item in alv grid or table control

In table control, If you goto screen painter and goto table control properties ( f2 ), there is one check-box w/selColumn check that and give column name. Then add that column to your internal table.
IN PAI
LOOP AT it_tkhdr.
    FIELD it_tkhdr-sel_row
      MODULE tab_tkhdr_mark ON REQUEST.
ENDLOOP.
MODULE tab_tkhdr_mark INPUT.
MODIFY it_tkhdr INDEX tc_tkhdr-current_line.
ENDMODULE.                 " tab_tkhdr_mark INPUT
here it_TKHDR is internal table sel_row is field for selection
After that, you can loop at it_tkhdr where sel_row is 'X' to get selected rows.

How to identify the modified rows in ALV grid in OO

Hello All,
I have strange problem and i don't know how to solve it?
I have ALV grid and in that ALV grid i have two buttons 'CONT' and 'ALLOC', when the user press 'ALLOC' button i will give a popup to make the user to enter some value.
After entering the value i will do some calicualtions and i will distribute the amount in the fields of ALV grid and i should update the ALVGRID.
Normally we can use CALL METHOD ME->REFRESH_TABLE_DISPLAY.( I have already checked by using this method and it worked fine)
Here is the way my program look like
ALVTREE1
ALVTREE2
             |----
ALVGRID
The problem is when i press the other button CONT i am unable to know what values exist in ALVGRID.
How can i find these distributed amount in ALV?
I hope i am clear while explaining problem.
Here is the required code:

Hello Vijay,
Thanks for you reply,
The event data_changed is not working because i called method refresh_table_display. So the event changed will not be raised after i press button CONT
If i didn't call this method then i can see the value enterd by the user in ALV grid.
So, do you have an more ideas.

Displaying the selected rows in ALV Grid output

Hi Experts,
I am developing one interactive ALV Grid report where user can process the selected records/rows from the ALV Grid output.
for displaying the ALV Grid, I have used the class CL_GUI_ALV_GRID class. I am working on ECC 6.0 system.
when I select any records/rows from output and then press any Application Toolbar button, PAI and then PBO modules of the screen gets executed as per the normal flow.
however After PBO, when same ALV output comes, all the selected/highlighted rows appear as unselected, that means I want to retain the ALV
rows selection during the round trip.
please advise.

Getting selected rows in ALV grid output

Hi All,
As per my requirement, in the ALV output i have 3 push buttons (Display, Edit and Print).
Using the below code, I am trying to get the selected rows from the output.
    CALL METHOD ob_grid->check_changed_data
      CHANGING
        c_refresh = w_x.
    CALL METHOD ob_grid->get_selected_rows
      IMPORTING
        et_index_rows = is_rows.
When I execute the code wid Display/Edit push buttons it is working fine as long as Print button is not used.
If I use the Print button and then try to select any other push button, I am not getting the entries in is_rows internal table.
Kindly help me.
Thanks in Advance.

Would your user actually select a row if they wanted simply to print?   I don't see that you're checking to see if the user actually selected a row ( after et_index_rows = is_rows, need to be sure is_rows is not initial (zero)).    Debug should show you exactly what is happening in the situation you described.

Selecting rows in ALV Grid using Classes

I am displaying the output in ALV grid format.
Now i am using cl_gui_alv_grid->Get_selected_ROWS to get the row index selected by User and on clicking a button it will take us to another screen which will hold the values of the selected row.
Problem Faced: But when we again go back to the first screen and select another row or same rows and click this button the selected rows index remains initial, that value is not getting captured.
I cleared the parameters and refershed grid also.
But the problem is not yet solved.
Please Give me the solution.

How to Edit selected row in ALV

Hi Experts,
I new to webdynpro ABAP. How to Edit the entire selected row in ALV. Please suggest?
Thanks in advance.

Hi,
I guess you have created the node as dynamic and also set this to the ALV..
1. Have you created READ_ONLY attribute of type wdy_boolean inside the node to which the ALV is bound..If not create it first and set the default value for this readonly as abap_true...ie X.
2. Got the contents in the internal table.
bind the table to the node..
3.Instantiate the ALV.
4. Now get teh column refrences of this ALV using the cl_salv_wd_config_table..and for columns
use the cell editor type as cl_salv_wd_uie_input_field...
loop through the column references and for all refrences create an object of type Input field and inside this class
use the method set_read_only_field_name ( 'READ_ONLY' ).
For the table settings if_salv_wd_table_settings of cl_salv_wd-config_table.. set the read only mode as abap_false..
5 create the custom button in the ALV using the cl_salv_wd_fe_button..
6 In this go for the events ON_FUCNTION and inside this method..do the coding
7 .Initially the table will be set to non editable..
In the button handler....
Get the refernece of this node to which the ALV is bound.....
lr_node = wd_context->get_child_node( 'VBAK' ). "dynamic node name
lv_index = lr_node->get_lead_selection_index ( ).
loop at it_table into ls_table.
if sy-tabix eq lv_index.
ls_table-read_only = abap_false. "editable
else.
ls_table-read_only = abap_true. "non editable
endif.
modify table
endloop.
lr_node->bind_table( lt_table ).
If you have any doutbs just refer the previous thread posted on the same..
You can follow the above steps to acheive thjs..

Lekha.

How to delete a particular row in ALV table

Hi,
How to delete a particular row in ALV table based on some condition(by checking value for one of the columns in a row)
Thanks
Bala Duvvuri

Hello Bala,
Can you please be a bit more clear as to how you intend to delete the rows from your ALV? By the way deleting rows from an ALV is no different from deleting rows from a normal table. Suppose you have enabled selection property in ALV & then select multiple rows and click up on a button to delete the rows then below would be the coding: (Also keep in mind that you would have to maintain the Selection property of the context node that you are binding to your ALV to 0..n)
data : lr_table_settings TYPE REF TO if_salv_wd_table_settings,
             lr_config          TYPE REF TO cl_salv_wd_config_table.
lr_table_settings ?= lr_config.
** Setting the ALV selection to multiple selection with no lead selection
lr_table_settings->set_selection_mode( value = cl_wd_table=>e_selection_mode-multi_no_lead ).
Next delete the selected rows in the action triggered by the button:
METHOD onactiondelete_rows .
DATA: wd_node TYPE REF TO if_wd_context_node,
         lt_node1 TYPE ig_componentcontroller=>elements_node,
         wa_temp TYPE REF TO if_wd_context_element,
         lt_temp TYPE wdr_context_element_set,
         row_number TYPE i VALUE 0.
wd_node = wd_context->get_child_node( name = 'NODE' ).
CALL METHOD wd_node->get_selected_elements
    RECEIVING
      set = lt_temp.
LOOP AT lt_temp INTO wa_temp.
    wd_node->remove_element( EXPORTING element = wa_temp ).
ENDLOOP.
CALL METHOD wd_node->get_static_attributes_table
    EXPORTING
      from = 1
      to    = 2147483647
    IMPORTING
      table = lt_node1.
wd_node->bind_table( new_items = lt_node1 ).
ENDMETHOD.
If in case this isn't your requirement please do let me know so that I can try come up with another analysis.

How to Extract the selected line in alv?

Hi,
I am learning ABAP and i have a doubt.It is as follows.
In interactive reports, by clicking on a ROW we can display the line by using SY_LISEL in AT LINE_SELECTION event .
Now i want to have a pop up window when we click on a selected row of ALV report I want that single ROW to be displayed . How can i do this?

Hi Ravindra,
I think this is not possible with ALV reports because these use field catalogs unlike Interactive reports. Interactive reports only has the capability of popping up the data in the next list when clicked on row with the help of the events.
Hope this helps.
Please reward if useful.
Thanks,
Srinivasa

How to hide selection column from alv grid

hi
i want to hide selection columns form alv grid.. how can i do it.. Is there any fm for that?
regards
palak

Hi,
the ALV Grid Control allows you to directly hide key columns with NO_OUT (field KEY_SEL is not used).
Field name:NO_OUT
Comp. type:LVC_NOOUT
Dtype(length):Char(1)
SPACE, 'X'
If you set this field, you hide the relevant column in the list. Nevertheless, the column is available in the field selection and can be interactively selected by the user as a display field. The ALV displays the contents of hidden fields on the detail screen for a row in the grid control.
Regards,
Neenu.
