how can select emaild id on button click of listview & send mail service on particular mail service id.

when asp.net element post server, beingness done using asp's premade javascript function __dopostback :

<script> function __dopostback( eventtarget, eventargument ) { document.form1.__eventtarget.value = eventtarget; document.form1.__eventargument.value = eventargument; document.form1.submit(); } </script>

if want pass html listview element code behind, can intercept button click , submit email_id in __eventargument argument thats beingness sent server.

for example, can run javascript function on asp.net button click, prior posting using onclientclick:

<asp:button id="bt_send" runat="server" text="send" onclick="bt_send_click" onclientclick="submit_stuff" /> function submit_stuff(){ //get email id here var _email_id = "blablabla1"; //manually cause postback email id argument __dopostback('<%=bt_send.clientid%>',_email_id ); homecoming false; }

and in code behind, either on page load or on bt_send_click function retrieve argument:

dim email_id string = request.form("__eventargument")
