Hi jaxrpc,


I found this at (http://www.windowsforms.net/FAQs/default.aspx?PageID=2&ItemID=538&CategoryID=3&tabindex=3).  You should be able to use this to create a custom scrollable datagrid, just keep an integer in your form that keeps track of the current row.

Dim currentRow as integer = 0

'This is the scroll down button code
Private Sub downButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles downButton.Click
    currentRow += 1
    Me.yourDataGrid.ScrollToRow(currentRow)
End Sub



How do I programmatically scroll a DataGrid to a particular row?      

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
