Changing ALV toolbar at runtime

[Former Member]

In my program which allows to edit records and then save into a table using ALV grid, I am using CL_GUI_ALV_GRID=>MC_EVT_ENTER to trigger the DATA_CHANGED event. Also I am showing the SAVE button using the TOOLBAR event in the ALV's toolbar and not on the GUI status of the program. What I intend to achieve is as follows;

After editing or entering new data and then hitting the "CHECK" button which inturn triggers the DATA_CHANGED event in which I capture the changed/new data, then I would like to enable the SAVE button, until then it is disabled. Any ideas on how would I achieve this? Any event or method that I can invoke?

Code an event receiver with a method to handle the toolbar.

• LOCAL CLASSES: Definition

*===============================================================

CLASS lcl_event_receiver DEFINITION DEFERRED.

• class lcl_event_receiver: local class to

• handle your own functions.

• Definition:

CLASS lcl_event_receiver DEFINITION.

PUBLIC SECTION.

METHODS:

handle_toolbar

FOR EVENT toolbar OF cl_gui_alv_grid

IMPORTING e_object e_interactive,

PRIVATE SECTION.

ENDCLASS.

• Define event receiver reference variable

data:

event_receiver TYPE REF TO lcl_event_receiver.

CLASS lcl_event_receiver IMPLEMENTATION.

METHOD handle_toolbar.

• In event handler method for event TOOLBAR: Append own functions

• by using event parameter E_OBJECT.

DATA: ls_toolbar TYPE stb_button.

*....................................................................

• E_OBJECT of event TOOLBAR is of type REF TO CL_ALV_EVENT_TOOLBAR_SET.

• This class has got one attribute, MT_TOOLBAR, which

• is a table of type TTB_BUTTON. One line of this table is

• defined by the Structure STB_BUTTON (see data declaration above).

*

• A remark to the flag E_INTERACTIVE:

• ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

• 'e_interactive' is set, if this event is raised due to

• the call of 'set_toolbar_interactive' by the user.

• You can distinguish this way if the event was raised

• by yourself or by ALV

• (e.g. in method 'refresh_table_display').

• An application of this feature is still unknown...

• append a separator to normal toolbar

CLEAR ls_toolbar.

MOVE 3 TO ls_toolbar-butn_type.

APPEND ls_toolbar TO e_object->mt_toolbar.

• append an icon to show booking table

CLEAR ls_toolbar.

MOVE 'CONVERT' TO ls_toolbar-function.

• MOVE icon_employee TO ls_toolbar-icon.

MOVE 'Base Unit/Lbs'(111) TO ls_toolbar-quickinfo.

MOVE 'Base/Lbs'(112) TO ls_toolbar-text.

MOVE ' ' TO ls_toolbar-disabled. <<<this is where you would enable the save button

APPEND ls_toolbar TO e_object->mt_toolbar.

ENDMETHOD.

*********************

in PBO

• Create Object to receive events and link them to handler methods.

• When the ALV Control raises the event for the specified instance

• the corresponding method is automatically called.

*

CREATE OBJECT event_receiver.

SET HANDLER event_receiver->handle_user_command FOR r_grid_det.

SET HANDLER event_receiver->handle_toolbar FOR r_grid_det.

• Call method 'set_toolbar_interactive' to raise event TOOLBAR.

• raise event TOOLBAR:

CALL METHOD r_grid_det->set_toolbar_interactive.

Hi Kshitij

Calling the method <b>"set_toolbar_interactive"</b> should trigger the event <b>"toolbar"</b> where you can control states for your buttons.
