[RESOLVED] Enable/Disable Column in a DataGrid?

[fdunford]

I tried this but it seems to do absolutly nothing.

Private Sub Session5SupportedCheckBox_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Session5SupportedCheckBox.CheckedChanged
        If Session5SupportedCheckBox.Checked = True Then
            dtService.Columns.Item(6).ReadOnly = False
            DataGridServices.Refresh()
        Else
            dtService.Columns.Item(6).ReadOnly = True
            DataGridServices.Refresh()
        End If
    End Sub
