Join two string properties (firstName + lastName) of usercontrol and assign it to label
<p>I made a custom usercontrol which contains a label.
I have 3 string properties : firstName, lastName, fullName.</p>

<p>How can I set the label's text = FullName ?</p>

<pre><code>    public string firstName
    {
        get; set;
    }

    public string lastName
    {
        get; set;
    }

     public string fullName //this fails
    {

        get { return string.Format("{0} {1}", firstName, lastName); }
        set { labelFullName.Text = value; }
    }
</code></pre>
