title: How to post table rows, added via Javascript, to the server in ASP.NET?
body: <p>This question has been asked before: <a href="https://stackoverflow.com/questions/6979049/access-asptable-table-rows-added-by-javascript-in-asp-net-webform">Access &lt;asp:table&gt; table rows added by javascript in asp.net webform</a> . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.</p>
  
  <p>If I have a &lt;HTML&gt; table or an &lt;asp:table&gt; control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?</p>
  
  <p>I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.</p>
  
  <p>I would have thought there was a way to include these new rows in the post-back, the same as any client-side user input?</p>
