Resize Grid

Ver 2.6.4

I am dynamically changing the height of a grid.

gridData.setSize(curWidth,newHeight);
gridData.refresh();

When I do that, if the grid is taller after resize, the visible rows are the same as before, until I use the scroll bar. If I scroll down, all rows are visible, if I scroll back up to original position, then the original # rows only visible.

Anything I can do to show all the rows.

Thanks,

I have the same problem.
Who can give me a solution?
Thanks in advance.
