EDIT ALV TREE

Hi all,
I followed SAP example program to create 'COLUMN structure ALV tree' to diaplay and i have to make some of the fields as editable and get back the changed values in the internal table.Here i did not use field catalog at all.
I used gui_custom_container,cl_gui_custom_container,cl_gui_column_tree ...and added every column to the the tree object .Built the node with two internal table(like order header & order item ) to form a tree.How should i get the changed values in the internal table when user changes values in Colums of order item node.
Any help is appreciated.
thanks,
dan.

Hello all,
Thanks for you reponses.I was actually referring COLUMN_TREE_CONTROL_DEMOF01,now kind of changing the code like BCALV_TREE_DEMO, BCALV_TREE_SIMPLE_DEMO .Looks like i can make the field as editable by changing the edit field in layout object.But unlike 'GRID' object this tree object is not having any method like 'check_change_data' .
How to get back the changed/values in iternal table or by any other means.
Any idea of getting changed values from ALV tree object would be really helpful.
thanks,
dan

Hi Karan
CL_GUI_ALV_TREE is only a display tool.
It has not a feature for editable data unfortunately.
I was used a popup input screen on cell "double click" event to change the data in a cell
in one of my projects.
Maybe it can be a solution for u .

You do this with the following code example
DATA: ls_layout TYPE lvc_s_layi.
CLEAR ls_layout.
ls_layout-class     = cl_item_tree_control=>item_class_text.
ls_layout-editable   = 'X'.
ls_layout-fieldname = your fieldname.
APPEND ls_layout TO lt_layout.
add PO header to tree
      CALL METHOD tree->add_node
        EXPORTING
          i_relat_node_key = space
          i_relationship   = cl_gui_column_tree=>relat_last_child
          i_node_text      = l_node_text
          is_outtab_line   = ls_po_item
          is_node_layout   = wa_layout_node
          it_item_layout   = lt_layout

Hello
The ALV tree control is not intended for making values editable (e.g. see
[How to make ALV tree columns editable|http://sap.ittoolbox.com/groups/technical-functional/sap-abap/how-to-make-alv-tree-columns-editable-2052414])
However, if you need an editable tree control then you have to use a different class (e.g. CL_ITEM_TREE_MODEL or CL_COLUMN_TREE_MODEL) but you will not have the ALV functionality of the ALV tree control.

ALV Tree with editable checkbox

Hi all,
I have a ALV Tree with editable checkbox (for all the parent & leaf nodes) , as one of the column.On clicking of a button in toolbar , i should get the nodes which are checked in checkbox.
But the problem is i am not able to get the nodes which are checked through checkbox in the PAI of the screen,when the button is clicked.
I tried using
CALL METHOD wf_tree->get_checked_items
 IMPORTING
 et_checked_items = lint_selected_node.
but the return table is not containing any entries , even if check boxes are checked in ALV tree.I tried the GET_CHECKED_ITEMS method in event handler method of AFTER_USER_COMMAND and also CHECKBOX_CHANGE , but no success.
lfs_item_layout-fieldname = 'CHECK'.
lfs_item_layout-class = cl_gui_column_tree=>item_class_checkbox.
lfs_item_layout-editable = 'X'.
lfs_item_layout-CHOSEN = 'X'.
APPEND lfs_item_layout TO lint_item_layout.
CALL METHOD wf_tree->add_node
 EXPORTING
 i_relat_node_key = p_lfs_final_key
 i_relationship = cl_gui_column_tree=>relat_last_child

 is_node_layout = lfs_node
 it_item_layout = lint_item_layout

Friends ,if you can suggest something.

hi ,
i have written below code for registering the CHECKBOX_CHANGE event of CL_GUI_ALV_TREE.
APPEND lfs_event TO lint_events.
 lfs_event-eventid = cl_gui_column_tree=>eventid_CHECKBOX_CHANGE.
APPEND lfs_event TO lint_events.
CALL METHOD wf_tree->set_registered_events
 EXPORTING

 SET HANDLER lo_event_receiver->handle_checkbox_change FOR wf_tree.

 ENDIF.
Also according to below code , i have put a break point in the event handler method of CHECKBOX_CHANGE event , so that control shall come here when check box is checked on ALV tree ...
CLASS lcl_event_receiver DEFINITION.

 CALL METHOD wf_tree->get_checked_items

 break abhijeetg.
ENDMETHOD.
ENDCLASS.
So according to you , I should get the control in the break point , but its not happening with this .. any thing missing ???

How to make editable cell in ALV TREE?

Hi all,
I have a problem to make the cell in item row (I mean not the cell in hierarchy columns and not in the node row) in ALV tree editable.
I know to make it in "normal" ALV, but my ALV is type class: cl_gui_alv_tree and the nodes are calculated in a sum.Can anyone help me to set the cell editable in ALV tree?
Thank you a lot!
Best regards,
Danijela Zivanovic

HI,
To make a column editable, it will be sufficient to set the field EDIT in the field catalog. The ALV Grid perceives if there are some editable fields and adds buttons for editing purposes. If you do not need these new buttons
if you want it in the Classes
For this procedure; add the name of the field to the field FIELDNAME, and pass cl_gui_alv_grid=>mc_style_enabled to make a field editable and cl_gui_alv_grid=>mc_style_disabled to make a field non-editable,
Example:
FORM adjust_editables USING pt_list LIKE gt_list[] .
DATA ls_listrow LIKE LINE OF pt_list .
DATA ls_stylerow TYPE lvc_s_styl .
DATA lt_styletab TYPE lvc_t_styl .
LOOP AT pt_list INTO ls_listrow .
IF ls_listrow-carrid = 'XY' .
ls_stylerow-fieldname = 'SEATSMAX' .
ls_stylerow-style = cl_gui_alv_grid=>mc_style_disabled . APPEND ls_stylerow TO lt_styletab .
ENDIF .
IF ls_listrow-connid = '02' .
ls_stylerow-fieldname = 'PLANETYPE' .
ls_stylerow-style = cl_gui_alv_grid=>mc_style_enabled . APPEND ls_stylerow TO lt_styletab .
ENDIF .
INSERT LINES OF lt_styletab INTO ls_listrow-cellstyles . MODIFY pt_list FROM ls_listrow .
ENDLOOP .
ENDFORM

Alv tree editable fields?

Hi gusrus does any one knows if there is a way to set an entire
column editable or maybe only a cell in an alvtree
thanks

ok first you have to register the alv tree event handler for double click, once you have done this you need to use the method
g_alv_tree->get_selected_item, once you have got the selected node by using the g_alv_tree->get_selected_item , you have to use the method g_alv_tree->get_outtab_line, then use the function 'POPUP_GET_VALUES', and finaly use the method g_alv_tree->change_item where you can insert the obtained values from 'POPUP_GET_VALUES'.
thanks i hope you can solve your problem, let me know if you want to receive my source code because i think is complex explaning by here.
regards
