Drop Down in ALV Flashes and Disappears.

[Former Member]

Hi All,

I have a strange issue going on. In an ALV (built on CL_GUI_ALV_GRID) I have got an editable field with a drop down option.Now lets say I have 10 rows in an ALV. I chose an entry from the drop down in one of the rows (this happens OK) and immediately after that I go on a click on drop down for any other row. What happens is that the drop down for the new row that I am in flashes and disappears. Now if I click for the drop down again the drop down appears. Basically whenever an entry is selected in one of the rows, drop down function immediately after that does not work. I have a feeling that it has something to do with the data _changed event but I am not sure how to handle that event.

I saw a similar thread [ALV Menu Flash|; but could not figure it out.

Any suggestions ?

Thanks

Hi,

Let us see the code and check it

Make the necessary changes at the fieldcatalog

clear ls_fcat.

ls_fcat-fieldname = 'COURSE'.

ls_fcat-col_pos = 5.

ls_fcat-coltext = 'Course'.

ls_fcat-outputlen = 10.

ls_fcat-DRDN_HNDL = 25.

ls_fcat-edit = 'X'.

APPEND ls_fcat to lt_fcat.

and in the class cl_gui_alv_grid we have one method SET_DROP_DOWN_TABLE

and it is having one parameter called iT_DROPDOWN of type LVC_T_DROP

generate the internal table and call the method set_drop_down_table

clear ls_drop.

ls_drop-handle = '25'.

ls_drop-value = 'ABAP'.

append ls_drop to lt_drop.

clear ls_drop.

ls_drop-handle = '25'.

ls_drop-value = 'CRM'.

append ls_drop to lt_drop.

clear ls_drop.

ls_drop-handle = '25'.

ls_drop-value = 'WEBDYNPRO'.

append ls_drop to lt_drop.

CALL METHOD o_grid->set_drop_down_table

EXPORTING

it_drop_down = lt_drop.

Thanks & Regards.
