Attributes.Add - works independently, not together
<p>I have two attributes I would like to assign to the same event:</p>

<p><code>
ddlBuyer.Attributes.Add("onclick", "$('#tbxProdAC').val('');");
</code></p>

<p><code>
ddlBuyer.Attributes.Add("onclick", "$('#txtbxHowMany').val('');");
</code></p>

<p>If I comment one out, the other other works fine. But if I just leave both lines in, only one is fired.</p>

<p>Can someone explain to me the logic behind this and further to that, how I should nest this so that when ddlBuyer executes the onclick event, both txtbxHowMany &amp; tbxProdAC return the value of ''></p>
