printing data grid

how do i create a print preview for a datagrid control currently displayed, and later print it out in a customized report format? any help would be appreciated. thanks

i am currently working on doing just that, but havent had any luck yet. anyone that could help... the code needs to be transferred to VB.net. This would be a powerful tool, because printing xml files are unreadable to a user, so if you can print the data like a datagrid, it would solve the problem. anyway, here is code that will print the raw data...

VB Code:

Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage 
        Dim LinesPerPage As Single = e.MarginBounds.Height / PrintFont.GetHeight(e.Graphics) 
        Dim Line As String = Nothing, count As Integer, yPos As Single = 0 
        For count = 0 To LinesPerPage - 1 
            Line = StreamToPrint.ReadLine 
            If Line Is Nothing Then Exit For 
            yPos = e.MarginBounds.Top + count * PrintFont.GetHeight(e.Graphics) 
            e.Graphics.DrawString(Line, PrintFont, Brushes.Black, e.MarginBounds.Left, yPos, New StringFormat()) 
        Next 
        If Not (Line Is Nothing) Then e.HasMorePages = True 
    End Sub 
 
    Private Sub MenuItemPrintPreview_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItemPrintPreview.Click 
        StreamToPrint = New IO.StreamReader("temp.xml")  'whatever is bound to datagrid
        PrintPreviewDialog1.Document = PrintDocument1 
        PrintPreviewDialog1.ShowDialog() 
        If Not (StreamToPrint Is Nothing) Then 
            StreamToPrint.Close() 
        End If 
    End Sub
