Hi,

You can achieve this functionality through LAYOUT by passing 'X' to the layout-sel_mode.Then the Grid looks like a table control.

Hi Vinotha,

You can do that.

Do the style setting as to make it pushbutton.

In the class CL_GUI_ALV_GRID, there are constants starting by the name MC_STYLE..... Just assign the STYLE attribute of Fieldcatalog to the style corresponding to the push button .

That is it...problem solved.

Here is an example....

form PREPARE_CATALOG changing p_field_catalog type lvc_t_fcat.

DATA ls_fcat type lvc_s_fcat .

CLEAR LS_FCAT.

ls_fcat-fieldname = 'CARRID'.

ls_fcat-ref_table = 'SFLIGHT' .

ls_fcat-style = cl_gui_alv_grid=>mc_style_button.

ls_fcat-outputlen = '20' .

ls_fcat-coltext = 'Carrid' .

APPEND ls_fcat to p_field_catalog .

endform.

Regards,

SP.

hi,

Pushbuttons on the List To make a cell to be displayed as a pushbutton

we have two steps.

Firstly, insert a new inner table of type “LVC_T_STYL” into your list data table.

Fill this inner table for each field to be displayed as pushbutton.

Button click event is handled like hotspot click via the event “button_click” through its parameters “es_col_id” and “es_row_no” which contain the address of the clicked pushbutton cell.

This detail Is provided in

An Easy Reference for ALV Grid Control PDF page 32.

if u dont have the PDF .

Please give me ur Email address i will send u.

You cannot declare it as a button, but as an ICON or CheckBox only.

Add a single character field in your table. And when you are inserting the field in your field cat, check the field

ICON or

SYMBOL or

CHECKBOX or

Or you can declare the lay out as lvc_s_layo-sel_mode = 'A'

The event you could use to capture the actions is lcl_event_receiver

See sample from SAP, search BCALV* in SE38

Hi,

it is very well possible.Just check this Program.

and for responding you need the event BUTTON_CLICK

have a local class method, and implement that, and then set the handler for it to respond.

   <b> button_click         for event button_click
                         of cl_gui_alv_grid
                         importing es_col_id
                                   es_row_no</b>

i just used LVC fm, it is almost like using CL_GUI_ALV_GRID from this report take the bold alone, thats all.

to check the Button you copy paste and see the above code.

for button using cl_gui_alv_grid try the fieldcat which i marked as bold.

Thanks a lot...it worked...can u also..tell me how to disable the button...based on user entry.

Re: Adding a button on the ALV grid using OOPs

Former Member — Tue, 20 Jun 2006 13:04:14 GMT

Hi Vinotha,

You can disable the buttons in the standard toolbar in ALV using the method hide_functions.In that method, there is a parameter which should contain all the codes of the buttons you want to disable.

For more details, refer this document.

vinotha_m — Tue, 20 Jun 2006 13:36:55 GMT

No, I dont want to disable the standard buttons....i want to disable the buttons that i created on each row..using the style field of the fieldcatalg..

i.e a column entirely displayed as buttons.

Re: Adding a button on the ALV grid using OOPs

Former Member — Tue, 20 Jun 2006 14:05:01 GMT

Hi Vinotha,

You can disable the button style by setting the style as MC_STYLE_DISABLED.

for eg:

my_cat-style = CL_GUI_ALV_GRID=>MC_STYLE_DISABLED.

@Vijay Babu Dudla

Hi Vijay or anybody else that wants to answer me

I tried the program ZTESTALV. What I don't get is how to set the handler for the event BUTTON_CLICK. Do you have a code example how to create the handler when using the FM REUSE_ALV_GRID_DISPLAY_LVC?

Thanks and regards,

Stefan
