Despite the problems in TIB_GRID with multiselect of rows it is possible to
1. Detect when many rows have been selected.
2. Deselect them and detect when they have been deselected.
3. Change a selected row's boolean field and give that value to the other
selected rows.
4. Change a selected row's value in a embedded TIB_Lookupcombo and give that
value to the other selected rows.
5. Change a selected row's TDate field and give that value to the other
selected rows.

Perhaps there is an example of this published somewhere? If there is
interest I'll post some more details here.

Russell
