I'm trying to use a generic form to maintain several different tables in the database.  They all use the same form, but just different data sources.  What is the best way to do this in code at run-time instead of setting it through the designer at design time?  I figure I need to set some properties of the PopulationDataSourceSettings, but what I'm doing hasn't been working.  Here's the code I've got so far to bind the grid, and maybe someone can tell me what I have missing.

Public Class frmSFTableBase
   Public Sub New(ByVal HdrBO As BusinessLayer, ByVal HdrValue As String) 
      Me.BusinessObjects.Add(HdrBO)
      Me.grdHdr.PopulationDataSourceSettings.BusinessObjectType = "BBS.Biz.BizTypeBO"      Me.grdHdr.PopulationDataSourceSettings.ValueMember = HdrValue
      Me.grdHdr.PopulationDataSourceSettings.MethodToExecute = "FillDataTable()"
      Me.grdHdr.PopulationDataSourceSettings.DisplayFieldNames.Add(HdrValue)
      Me.grdHdr.PopulationDataSourceSettings.FormatColumns.Add("{0}", MicroFour.StrataFrame.UI.ListViewColumnPopulationType.FormattedString)
      Me.InitializeComponent()

End Sub

   Private Sub grdHdr_ListPopulating(ByVal e As   MicroFour.StrataFrame.UI.ListPopulatingEventArgs) Handles grdHdr.ListPopulating

       e.Parameters(0).Value = "SELECT * FROM BizType"
  End Sub

End Class

Ok, I now have this:

Me.grdHdr.PopulationDataSourceSettings.BusinessObjectType = "BBS.Biz." & HdrValue & "BO"
Me.grdHdr.PopulationDataSourceSettings.DisplayFieldNames.AddRange(New String() {HdrValue})
Me.grdHdr.PopulationDataSourceSettings.FormatColumns.Add("{0}", MicroFour.StrataFrame.UI.ListViewColumnPopulationType.FormattedString)
Me.grdHdr.PopulationDataSourceSettings.FormatString = "{0}"
Me.grdHdr.PopulationDataSourceSettings.MethodToExecute = "FillDataTable;System.String"
Me.grdHdr.PopulationDataSourceSettings.ValueMember = HdrValue

But on the first line it gives me an exception and the message on Me.grdHdr is "Object cannot be null".  It looks like for some reason my grid is Nothing, but I created it on the form at design time so what else do I need to do to have an instance of it?
