Hi,

Follow the below steps,

1. Declare a handler method for the event TOOLBAR of class cl_gui_alv_grid

2. For the above event you will have e_object as importing parameter.

3. In that e_object you will have mt_toolbar as a attribute which is a internal table.

4. In this internal table you will have details of all the buttons of toolbar.

5. Loop that internal table with the ICON name and modify the field disabled = 'X'.

Go through the standard program BCALV_GRID_05 for reference in which the functionality of adding a new button is present.

reward if helpful

Hello,

To exclude buttons, you fill a table of type UI_FUNCTIONS and pass it to the parameter IT_TOOLBAR_EXCLUDING of the method set_table_for_first_display. The function codes for the buttons may be acquired by inspecting the constant attributes of the class cl_gui_alv_grid or putting a break point into a method, like the event-handling method of the event after_user_command, which deals with the ALV command.

Follow an example:


FORM exclude_tb_functions CHANGING pt_exclude TYPE ui_functions .
DATA ls_exclude TYPE ui_func.
ls_exclude = cl_gui_alv_grid=>mc_fc_maximum .
APPEND ls_exclude TO pt_exclude.
ls_exclude = cl_gui_alv_grid=>mc_fc_minimum .
APPEND ls_exclude TO pt_exclude.
ls_exclude = cl_gui_alv_grid=>mc_fc_subtot .
APPEND ls_exclude TO pt_exclude.
ls_exclude = cl_gui_alv_grid=>mc_fc_sum .
APPEND ls_exclude TO pt_exclude.
ls_exclude = cl_gui_alv_grid=>mc_fc_average .
APPEND ls_exclude TO pt_exclude.
ls_exclude = cl_gui_alv_grid=>mc_mb_sum .
APPEND ls_exclude TO pt_exclude.
ls_exclude = cl_gui_alv_grid=>mc_mb_subtot .
ENDFORM .

Hello Venu

Have a look at my sample report ZUS_SDN_ALV_EVT_TOOLBAR. Execute the report and push the ENTER button repeatedly.

If you have choosen P_INACT = 'X' the toolbar functions are inactivated.

If you have chhosen P_DELE = 'X' the toolbar functions are deleted.

Hi,

Try this code for reference

want deactivate,,,,,some fuctions in alv grid...tel me how...

REPORT ZEDIT_ONE_CELL_OOPS.

*Essential steps (search for '§')

~~~~~~~~~~~~~~~
1.Extend your output table for a field, e.g., CELLTAB, that holds
information about the edit status of each cell for the
corresponding row (the table type is SORTED!).
2.After selecting data, set edit status for each row in a loop
according to field SEATSMAX.
2a.Use attribute CL_GUI_ALV_GRID=>MC_STYLE_ENABLED to set a cell
to status "editable".
2b.Use attribute CL_GUI_ALV_GRID=>MC_STYLE_DISABLED to set a cell
to status "non-editable".
2c.Copy your celltab to the celltab of the current row of gt_outtab.
3.Provide the fieldname of the celltab field by using field
STYLEFNAME of the layout structure.
