            End If
        Next
    End Sub

and

in my aspx forms, I write this code :

ClearPage(Me, "form1")

My question is, How do I find all controls in aspx forms that link to MasterPage ?
I have changed the code like this :

Public Sub ClearPage(ByVal Pg As MasterPage, ByVal Form As String, Optional ByRef ClearCombo As Boolean = False)
        Dim Obj As Object
        For Each Obj In Pg.FindControl(Form).Controls

        Next Obj

End Sub

and

   ClearPage(Master, "aspnetForm")

but not working !!!

Thanks,

Kusno.
