Changing ALV toolbar at runtime

Former Member — Mon, 28 Mar 2005 20:42:31 GMT

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

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

lcl_event_receiver (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.
