About ALV edit and refresh

[Former Member]

Hi all,

I implemented an ALV by using function 'REUSE_ALV_GRID_DISPLAY'. One of the fileds output is called 'DELETE' and I set it diplay as checkbox and editable. When the user click this field of one certain line , I want the program to check the line data and decide whether the checkbox can be set to 'X' , if not ,I will clear it anyway . Now I did the check in event HANDLE_DATA_CHANGED and clear the field in my iternal table , but the ALV doesn't refresh, so although the field in my internal table is initial, it display as 'X' in the ALV. If I refresh the ALV now , the 'X' disapear. I can't set the ALV refresh automatically because it doesn't run the USER_COMMAND event. How can I deal it? If my way is wrong, how to do it correctly? THANKS

Add a call to method refresh_table_display after updating the internal table.

You can use this method after modifying internal table.

data: go_grid TYPE REF TO cl_gui_alv_grid.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

E_GRID = go_grid.

CALL METHOD go_grid->CHECK_CHANGED_DATA .

Hi

i had tree based alv code with me

refer this

Add code to to the ALV Tree user command functionality

----

---

• CLASS lcl_toolbar_event_receiver IMPLEMENTATION

----

---

• ........ *

----

---

class lcl_toolbar_event_receiver implementation.

method on_function_selected.

data: ls_gmsec type zgmsec,

ld_answer type c.

case fcode.

when 'CHNG'.

data: ld_uname type zgmuserparam-uname.

data: lt_selected_node type lvc_t_nkey.

call method tree1->get_selected_nodes

CHANGING

ct_selected_nodes = lt_selected_node.

call method cl_gui_cfw=>flush.

data l_selected_node type lvc_nkey.

check not lt_selected_node[] is initial.

read table lt_selected_node into l_selected_node index 1.

call method tree1->get_outtab_line

EXPORTING

i_node_key = l_selected_node

IMPORTING

e_outtab_line = ls_gmsec.

if ls_gmsec-uname is initial.

message i010(ad) with 'Please choose a valid user'.

else.

• Example: i.e calls screen to allow user to make chnage

call screen 0300.

• AT this point user has returned from a screen (i.e. 300) which

• allowed them to make changes to existing data/node

• The following code deletes all the existing nodes using the top

• node table populated earlier

loop at it_topnodes into wa_topnodes.

call method TREE1->DELETE_SUBTREE

EXPORTING

i_node_key = wa_topnodes-nodekey.

endloop.

call method cl_gui_cfw=>flush.

• Now you need to re-select your data and re-build your hierarchy

• from scratch. for example the code could look somthing like this.

REFRESH: it_ekko, it_ekpo.

SELECT ebeln

UP TO 10 ROWS

FROM ekko

INTO corresponding fields of TABLE it_ekko.

loop at it_ekko into wa_ekko.

SELECT ebeln ebelp statu aedat matnr menge meins

netpr peinh

FROM ekpo

appending TABLE it_ekpo

where ebeln eq wa_ekko-ebeln.

endloop.

perform create_alvtree_hierarchy.
