Information

You can programmatically change the selected cells of an existing grid view using either of the following two system procedures: 

1. g2-ui-grid-view-replace-cell
2. g2-ui-grid-view-modify-cell

For instance, the procedure below demonstrates how to select cells 0,0 to 3,3 in an existing grid view: 

test( win: item-or-value )
X: Integer;
Y: Integer;
begin
  for X = 0 to 3 do
    for Y = 0 to 3 do
      call g2-ui-grid-view-modify-cell(
         the returned-dialog-id of grid-view,
         the symbol my-sole-grid-view,
         X, Y,
         structure( selected: true ),
         win
      );
    end;
  end;
end
