Summary Row Bottom of Datagrid

Well I have posted a picture with the issue. I cant seem to find any information about this.
I'm taking a guess my only option will be to fill textboxes with the sum of each column.

Since the datagrid doesn't fit to my winform I have a horizontal scroll bar what I would like to incorporate is have the summary while you scroll horizontally opposed to having textboxes underneath that scroll bar cause I would have to make the same scroll bar to scroll through the textboxes so they align with the columns. Hope that makes sense to you all.
