If you have a form with a Sienn file upload and it is a required field, the following code can be used.

Code:
Select FormId
    Case 4
        Dim FLBT As String = "FLBT10"
        Dim fileUpload As System.Web.UI.HtmlControls.HtmlInputFile = Nothing
        Pbw.Assign_Control(MyForm, FLBT, fileUpload)
        
        If fileUpload.PostedFile.ContentLength = 0 Then
            Return "No file was uploaded."
        End If
End Select
