How to make the vertical scroll bar return to left after each search

Hello,

I am having a grid which displays search results and also there is a vertical scrollbar. Before I do a search the scroll bar will be positioned to its default position left. After I do a search, Once I get the results in the grid, I move the scroll bar to extreme right to have a look at the value in the last column, Now when I do a search again at this point, the results will be refreshed and displayed but the scrollbar is still at the right position. How can I make the scrollbar to appear at its default position on left after each search.

Any suggestions please...
