I find that XamDataGrid  scroll horizontally in very small distance by clicking forward/backward button. I want to know whether I can set scroll horizontal by field(move a column each time). It looks ScrollInfo can set a constant value to SetHorizontalOffset. But field width is a variant. So it is not very easy to implement with SetHorizontalOffset.

Another problem is about the tool tip of vertical scrolling. I find the tool tip won't show the last Record when I slide the scroll bar to the bottom. Is this a problem?
