Ah okay, you can always use explicit interface implementation of course:

interface IControl
{
    string Id { get; set; }
    object Value { get; set; }
}

class Label : IControl
{
    public string Id { get; set; }
    public string Value { get; set; }

    object IControl.Value
    {
        get { return this.Value; }
        set { this.Value = (string)value; }
    }
}

class Repeater : IControl
{
    public string Id { get; set; }
    public IList Value { get; set; }

    object IControl.Value
    {
        get { return this.Value; }
        set { this.Value = (IList)value; }
    }
}
