selecting all in a groupbox [RESOLVED]

[Andy]

why wont this work? I get a message saying CHECKED IS NOT A MEMBER OF SYSTEM.WINDOES.FORMS..... yadda yadda

'This will select all
        If tab_TrblQue_chkViewAllorNone.CheckState = CheckState.Checked Then
            Dim ctrl As Control
            For Each ctrl In tab_TrblQue_grpMultiQueOptions.Controls
 
                If TypeOf ctrl Is CheckBox Then
                    ctrl.checked = True
                    '
                    '
                    '
                End If
 
 
            Next
 
            Exit Sub

I'm trying to check all checkboxes in a groupbox by selecting a particular checkbox
