ALV with pushbutton

Former Member — Mon, 29 Sep 2008 13:43:57 GMT

Hi all,

When I create a ALV output with grid(using REUSE_ALV_GRID_DISPLAY), during output display I want a pushbutton to be displayed BEFORE each row.The row should not be editable.When I select the button, the whole row should be selected.

What extra code should I add in my program?

Thanks,

Shivaa......

Have one more extra field in your internal table.

and specify that fieldname to the BOX_FIELDNAME of the layout.

and pass the Layout to the ALV function parameter.

nothing more than that.

Hi Vijay,

thnx for ur quick reply...

box_fieldname type slis_fieldname stands for 'fieldname for checkbox'.

But, I dont want checkbox, I want a pushbutton.

data: begin of itab occurs 0,
       ....
       ....
       box_field type c, 
      end of itab.

layout-box_fieldname = 'BOX_FIELD'. "it will show as button 
                                  "only

Don't worry, it will show as button only incase of Grid function.

data: itab like lfa1 occurs 3. "<---this internal table should hold a field name box_field

" or something else of type c

you have to define like this..

data: begin of itab occurs 0.
  include structure lfa1.
data: box_field type c.     "then only it will work.
data:  end of itab.
