ALV Tree Edit mode

Hi,
I have wrote a program using CL_GUI_ALV_TREE.
I want to make some of the columns editable.
Alternatively, is it possible to include a tree structure in normal CL_GUI_ALV_GRID?
Thanks.
Michael Pang

Hi Leif,
I have not achieved that myself. Maybe you could use a different approach: display the fields into the tree, then use another subscree to show the field contents and allow the user to chage it.
You could find useful these demo programs: SAPSIMPLE_TREE_CONTROL_DEMO, SAPCOLUMN_TREE_CONTROL_DEMO, SAPTLIST_TREE_CONTROL_DEMO, SAPTLIST_TREE_CONTROL_DEMO_HDR, because they show a tree and then, in another subscreen, they show some properties of the selected fields and so.
I hope it helps. Best regards,
Alvaro

How to make some fields in ALV tree editable

Hello All,
Can any one tell me how to make some fields in ALV tree editable.
If possible please post some code.
Regards,
Lisa.

Hi Lisa,
I want to make 3 fields in the ALV tree editable and update the saved values in ztable.
I tried making the wa_fieldcat-edit = 'X' But in vain.
Also i made the layout fields wa_layout-edit = 'X' and wa_layout-edit_mode = 'X'.
But still the alv tree field appears as display.
As you have mentioned in the post as answered, So please guide me to make the field editable.
I am using oops method.
Please provide me code if any.
Thanks & Regards,
Mozila

ALV GRID edit mode keyboard issue

Hi,
I have created a program that displays an ALV GRID.
From the Layout I said to edit in edit mode the ALV Grid.
In the menu toolbar I exclude the button 'cut - copy -paste and delete line'.
When I run the program I see that these buttons are not displayed --> OK.
BUT my problem is: if I use the keyboard then the ALV Grid manages these actions.
For instance. I select some lines and press the key DELETE on the keyboard --> the lines are removed and that is not that I expect because I removed this action from the toolbar.
For the cut - copy and paste it's the same.
Do you have a solution for me --> intercept an event or change the function keys or ....
I would like that the ALV Grid does not manage the keys delete, CRTL-C, CRTL-V in edit mode.
Thanks,
Stevie,

Hi Steve
I was not aware of this. So, I recommend you to try this:
At the event "before_user_command" you can terminate the process by resetting the ALV user command.
e.g.
 CASE e_ucomm .
 WHEN '&INFO' .
 CALL METHOD gr_alvgrid->set_user_command
 EXPORTING i_ucomm = space.
 ENDCASE .
This code within the event overrides the '&INFO' function and terminates its process. For cut and copy, you can find out ucomm values by putting a break point inside the event and tracing the value of "i_ucomm".
For some relevant issues, you can inspect the tutorial <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/documents/a1-8-4/an%20easy%20reference%20for%20alv%20grid%20control.pdf">"An Easy Reference For ALV Grid Control"</a>.

ALV in EDIT-Mode: can't hide the toolbar in edit-mode

Hi,
I have supressed in my ALV all standard-buttons with the help of an it_toolbar_excluding. I have built my own toolbar (p_object->mt_toolbar). Until know everything is fine, the ALV shows only my own generated toolbar.
In that moment, when I change a property of a column in the fieldcatalog ( wa_catalog-edit = 'X' ), both toolbars are shown, the standard toolbar and my own generated buttons.
What's wrong, how can I hide the standard toolbar when I am in the edit mode?
Kind regards
Andreas
Edited by: Andreas Waldt on Sep 3, 2008 5:19 PM

Thank you very much,
during testing I have recognized, that the buttons in the toolbar are new functions, because of the edit mode.
So I have put all the new button into the excluding list. It worked!
Thanks again!
Andreas

Hi there,
You can set the navigable and mouse-navigate property to no.
Then create a visual-attribute which you want to show when the user can't change the item.
When you want to change the visual_attribute for the item use:
set_item_property('<block>.<item>', VISUAL_ATTRIBUTE, '<name of attribute>'.
when you use enabled, the field is simply grey, but with the visual attribute you can show any color you like!
Hope this helps...

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.

O/P ALV in edit mode

Hi All,
Can any on tell me how to get the coloumns of the O/P ALV table in eit mode. I have an alv table ready its working fine.
All I know is I need to use some codes like
call method l_value->if_salv_wd_table_settings~SET_READ_ONLY
EXPORTING
    VALUE = ABAP_FALSE
along with method SET_CELL_EDITOR. But I am not able to implement it. Can anyone give me the details. The only thing ready is an alv table which takes i/p from select parameter and gies the data in the display.
I get a lot of syntax error and am not able to understand clearly .
Thanks in advance.
Rgds,
Anu.

I'm afraid you might have to clarify your question a little bit. What exactly are you needing help with? Are you just wanting to know how to interact with the ALV Table model. If so, you can do that via the component usage and the component interface. Here is a small example. The thing to keep mind is that the code must be adjust for what you named your alv component usage. For example in this code I named my component usage alv. Therefore the method names are wd_this->wd_cpuse_alv and wd_this->wd_cpifc_alv. If I had instead named the component usage XYX, the generated method names would change to wd_this->wd_cpuse_xyz and wd_this->wd_cpifc_xyz.
data: l_ref_cmp_usage type ref to if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
endif.
data l_salv_wd_table type ref to iwci_salv_wd_table.
l_salv_wd_table = wd_this->wd_cpifc_alv( ).
data l_table type ref to cl_salv_wd_config_table.
l_table = l_salv_wd_table->get_model( ).
l_table->if_salv_wd_table_settings~set_scrollable_col_count( 8 ).
data l_column type ref to cl_salv_wd_column.
l_column = l_table->if_salv_wd_column_settings~get_column( 'CLIENT' ).
l_column->set_visible( cl_wd_uielement=>e_visible-none ).
data textview type ref to cl_salv_wd_uie_text_view.
l_column = l_table->if_salv_wd_column_settings~get_column( 'ADD_PARTICIPANTS' ).
create object textview.
textview->set_text_fieldname( 'ADD_PARTICIPANTS' ).
textview->set_wrapping( abap_true ).
l_column->set_cell_editor( textview ).
l_column = l_table->if_salv_wd_column_settings~get_column( 'STATUS' ).
data ddlb type ref to cl_salv_wd_uie_dropdown_by_key.
create object ddlb
    exporting
      selected_key_fieldname = 'STATUS'.
ddlb->set_read_only( abap_true ).
l_column->set_cell_editor( ddlb ).
l_column = l_table->if_salv_wd_column_settings~get_column( 'CHANGED_BY' ).
l_header = l_column->get_header( ).
l_header->set_text( `Changed By` ).

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
