using Infragistics2.Excel.v9.2 and Infragistics2.Win.UltraWinGrid.ExcelExport.v9.2

After exporting a grid to a workbook, how can I actually open the workbook for the user to see.  i'm currently doing this

Public Sub ExportGridToExcel(grid As UltraGrid)
        Dim FilePath As String = gbMyDocumentsFolder & "PSA_" & VB6.Format(Today, "mmddyyyy") & VB6.Format(TimeOfDay, "hhmmss") & ".xls"
        Dim exporter As UltraGridExcelExporter = New UltraGridExcelExporter()
        AddHandler exporter.BeginExport, AddressOf HandleExcel_BeginExport
        exporter.Export(grid, FilePath)
        Process.Start(FilePath)
    End Sub
