Get width of control with not set width
<p>I have gridview and chart below it.</p>

<p>I want gridview stretch depending on number of columns (not set width) and after that to assign that width to chart.</p>

<p>If I do:</p>

<pre><code>chart.Width = gridview.Width.Value; 
</code></pre>

<p>I get 0.0 pixels.</p>
