we change values in a fixgrid and want navigate by arrowkeys.
we've got a bug: if we change rowselection by arrowkey, the selected row is rendered and we go down. the whole value (field) is marked.so we can put the new value without delete
if this row is out of the visible grid, the selection goes down and the grid scroll down... the row is rendered BUT the value of the field isn't marked (only curser)... so we must mark the value or delete this...
the "internal problem" is: when scrolling in the last row, then the data behind the components scrolls, so the focus stays in the same component - as conseqeuence there is no "selectAll" as when navigating from one component to the next...
