Question

I have this:

public static void Remove<T>(string controlID) where T: new()
{
    Logger.InfoFormat("Removing control {0}", controlID);
    T states = RadControlStates.GetStates<T>();

    //Not correct.
    (states as SerializableDictionary<string, object>).Remove(controlID);
    RadControlStates.SetStates<T>(states);
}

states will always be a SerializableDictionary with string keys. The values’ type vary. Is there a way to express this? Casting to SerializableDictioanry<string, object> always yields null.

You can use the non-generic dictionary interface for this:

(states as IDictionary).Remove(controlID);
