datagrid total

[davebat]

I have a datagrid which is bound to a filtered dataview, what is the best way to go about totalling the numerical values and putting them in the footer

Dim dr As DataRowView
        Dim range01tot As Decimal = 0.0
        Dim i As IEnumerator = dvOne.GetEnumerator()
        While (i.MoveNext())
            dr = i.Current
            range01tot += (dr("value"))
        End While
