you should not causing full postback this. trying call javascript function asp.net submit button, changing

<a href="javascript:void(0)" onclick="sendmail('<%=customertextbox.clientid %>')">             <asp:button id="cmdemail1" runat="server" text="generate email rma"                  width="158px" />             </a>  

to this:

  <a href="#" onclick="sendmail('<%=customertextbox.clientid %>')">             generate email rma             </a>  

will start make web development life easier , more scalable.
