Checkbox issue in OOALV

[Former Member]

Hi Everybody,

In my output ALV table, i have two cloumns with checkboxes. At time, user cannot check both the checkboxes, how to do this validation?

In my code i have used

CALL METHOD w_ref_alv_grid->check_changed_data

IMPORTING

e_valid = w_valid.

IF w_valid EQ 'X'.

But it is not triggering, when the user checks the checkbox, how to capture this event? how to do the validation?

Needy help will be appreciated.

Hi,

Put hot spot for the check box, In the event of hot spot click ,..

call method check_changed _data of alv grid which updates your internal table,

then loop the internal table and check if both the check boxes are selected or not., If selected display error message..

else instead of hot spot, which calls the event each time., put a save button, In on click of save button and do the same as above.,

hope this helps u.,

Thanks & Regards,

Hello friend,

I think this link will be useful for you to solve your issue.

You can use the method o_grid->check_changed_data( ). and capture the values for the check box.

Still have the same problem revert back to me.

Thanks,

Sri Hari

Hi,

Try using ALV event 'DATA_CHANGED' for both the checkbox entry (checked/unchecked)

In the implementation method, update the internal table with the checkbox value and place the validation code for chkbox.

When the event is triggered for 1st chkbox, update the internal table. Now when the event gets triggered for 2nd checkbox, validation code executes as per your requirement.

No need of validation. When clicked remove the check from other one and place it in the clicked one. Check the example below :
