title: Access <asp:table> table rows added by javascript in asp.net webform
body: <p>have an app that is trying to capture several entries added to an  control by the user. The user enteres data into a single text box and then clicks add.  This value is then appended to the table like so: <code>&lt;tr&gt;&lt;td&gt;some value&lt;/td&gt;&lt;/tr&gt;</code></p>
  
  <p>I'm trying to avoid round trips so the server but so far am having trouble. The form posts back but the new added rows aren't in the .Rows collection... is this possible to do?</p>
