How to get a list of controls on a asp page and set an attribute dynamically?
<p>So I was told the following would not be possible:</p>

<p>I have a aspx page that has a number of dropdowns.  Each dropdown is set with either a class=leftcolumn or class=rightcolumn.</p>

<p>I need to assign an attribute:</p>

<pre><code>propertyID.Attributes["nameOfAttribute"] = "false";
</code></pre>

<p>But instead of manually writing out each controlID and setting its attribute with the line above, I had hoped there was a way to go through and set the attribute on each control ID if it had class=leftcolumn.  </p>

<p>This is something I know is possible to do through JQuery easily, but I need it on the code behind during load.</p>

<p>Thanks,</p>
