HSCROLL-POS (numeric)

This property controls the current scrolling position of the horizontal scroll bar, specifying the column number of the left-most column currently visible in the grid. When row-headings are used, HSCROLL-POS specifies the column number that would appear in column one of the grid if there were no headings.

Note that scrolling is limited to the normal scrolling range. If you specify a value larger than the highest allowed value, the latter value is used. If you specify a value less than 1, you will receive undefined results. If the grid does not allow scrolling in the specified dimension, setting this property has no effect.
