as you can see in the "ID Campione" column there is only one value for the whole group, and at the end of the group there is a black line to divide it from the next one.
Could you help me?
Did you try to set grid.PageMode = false and call grid.Group(columnindex of ID Campione) ?
yes I've tryed but i obtain only that the column id campione become the "header" of the Group and the "tree column" of the Group will be showed.
I would that the column remain in it's original position, and that a black line is showed at the end of the group.
My goal is to remove a twwdbgrid that is present on my project and replace it with a TDBAdvGrid with minimal impact over the users of the software.
Also I've noticed that twwdbgrid have a very easy system to configure and edit column of the grid while the system adopted with TDBAdvGrid is less easy. But this is only a problem for the programmer non for the final user. :)
Then this is not really grouping, i.e. you do not have a collapse-able node.
