<form action="/Sp/EditSp" method="post" onclick="Sys.Mvc.AsyncForm.handleClick(this, new Sys.UI.DomEvent(event));" onsubmit="Sys.Mvc.AsyncForm.handleSubmit(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, httpMethod: &#39;POST&#39;, updateTargetId: &#39;divDisplay&#39;, onSuccess: Function.createDelegate(this, deactivateAList) });"><input type="hidden" id="requestSequence" name="requestSequence" value="24" />
