Scrolling and ViewRange

When the user selects a cell using the mouse or keyboard, the FlexGrid automatically ensures it is visible by calling the scrollIntoView method.

The scrollIntoView method causes the grid to scroll as needed so the requested cell is within the current viewRange. The grid will scroll the minimum amount needed to show the cell, so it may become visible at the top, middle, or bottom of the view range.

If you want to show a specific row at the top of the view range, you need a slightly different approach: get the bounding rectangle of the cell you want to show to the top and use the coordinates to set the grid's scrollPosition property.
