That is what the BusinessBindingSource control does for you.  If you drop (or create a variable) on you form, you can the set the BusinessObject property to any business object.  This basically wraps the BO and provides the IBindingList interface as well.

Hya.

I am trying to bind an XtraReport label to a BO field.

Does our BO implements the IList, ITypedList or IBindingList interface? That's what the XtraReport asks me in the help file.

I get an error after I set the report DataSource to the BO :

Private Sub RelEmpresasToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RelEmpresasToolStripMenuItem.Click
Dim Report As New rptEmpresas()
Dim loEmpresas As New ProFilmeNET_BOL.boEmpresas()
loEmpresas.FillDataTable("Select * from Empresas")
Report.DataSource = loEmpresas
Report.lblNome.DataBindings.Add("Text", loEmpresas, "emp_Descr")
Report.ShowPreviewDialog()
End Sub

Any word of advice to direct me in the right direction will be appreciated.

Thanks in advance.
