how can we set the property of Viewstate?
<p>I am using a enum</p>

<pre><code> public enum WatchUsageMode
    {
        Watch = 1,
        EmailPreferences = 2
    }
</code></pre>

<p>i want to set the property of that enum in my view state in such a way that whenever view state is null return Watch else EmailPreference.how can i get and set the property?</p>
