How can I access a GridView on a page from a control on a Page?
<p>I have an aspx page which has a GridView and a Panel with Summary Data.  The Summary Data is in a control and the GridView is on the aspx page.  When someone clicks an item in the Summary Data, I want to rebind the GridView, but I can't figure out how to do it from the control.</p>

<p>I tried using FindControl, but probably did not use it correctly.</p>

<p>I tried this with FindControl, but it didn't work:</p>

<pre><code>GridView gv = (GridView)FindControl("gvSearchResults"); //returns null
</code></pre>
