ComboBox object not accessible by me
<p>This is probably easy to solve, but the following cannot be done:</p>

<pre><code>protected void gSelectApplied(object sender, EventArgs e)
{
    ComboBox box = (ComboBox)sender; 
}
</code></pre>

<p>Because the ComboBox object is not present in the imported libraries. I went ahead an looked at the Microsoft documentation and I do not have access to the System.Windows.* libraries.</p>
