I've put two CB, the first is the grand parent FK, this CB has to pass a value to the other CB filtering this one's data and showing only data filtered by the other  CB.

For example I select a Customer Grand Parent CB, then an order (parent CB) and I fill in a form the data of one (and only one) item.

I tried a lot of examples I saw at the forum but with no success. My question is, I now how to do it manually, but I think there must be a more powerfull way via the framework.

I've bounded my first CB to a BO using the populationdatasourcesettings. This one works fine.

Then Ive bounded the second one using the method copydatafrom.

Ive put this code in the ListPopulating method

    Private Sub cboEstablecimientos_ListPopulating(ByVal e As MicroFour.StrataFrame.UI.ListPopulatingEventArgs) Handles cboEstablecimientos.ListPopulating

        e.Parameters(0).Value = Me.BoEmpresa1
        e.Parameters(1).Value = MicroFour.StrataFrame.Business.BusinessCloneDataType.ClearAndFillFromDefaultView
    End Sub

    Private Sub BoEmpresa1_Navigated(ByVal e As MicroFour.StrataFrame.Business.NavigatedEventArgs) Handles BoEmpresa1.Navigated
        Me.cboEstablecimientos.Requery()

    End Sub

But when I debug it it never reaches this code.

I must have some wrong parameter but I don't know which is.

Help please!!!
