Object ALV Grid - Line selection

[Former Member]

Hi all.

Is there a way to force my grid to have allways a selected line.

If possible I would like to see the row marker and I don't want users to be able to select more than one line.

I tried all layout sel_mode... but I didn't find the result I desire...

Do you have an idea ?

Thanks a lot
