>As long as your incremental search textbox is searching the same table as displayed in the grid, place the following in the InteractiveChange method of the Incremental search textbox:

Sorry, I see you already refresh grid. You can also add

ThisForm.LockScreen = .t.
ThisForm.GridName.SetFocus()               && This will mark the record.
do while thisform.gridname.relativerow>1   && This will scroll the selected
   thisform.gridname.doscroll(1)           && record to the first row in grid
enddo                                      && (this is optional code).
This.SetFocus()
ThisForm.LockScreen = .f.

I am writing this from memory (I do not have my code at my disposal right now). But this is general idea of what to do.
