DropDownList + ViewState (Validation requirement)

    >From a security perspective: Is it required to programmatically check
    if a DropDownList Postback 'SelectedValue' actually exists in the
    selection list previously rendered to the client? In other words: upon
    postback, when the DropDownList control Change event fires and the
    'old' ViewState is compared with the 'new' selection (the
    posted value) will the runtime throw an exception if the new value is
    not defined in the DropDownList loaded ViewState?

    Thanks
