The DataGrid has a protected GridVScrolled member that can be used to scroll the grid. To use it, you can derive from DataGrid and add a ScrollToRow method. Here is a code snippet.

Public Class MyDataGrid
    Inherits DataGrid
  Sub ScrollToRow(ByVal row As Integer)
    If Not Me.DataSource Is Nothing Then
      GridVScrolled(Me, New ScrollEventArgs(ScrollEventType.LargeIncrement, row))
    End If
  End Sub
End Class
