推荐答案

<asp:button id="btnDownload" runat="server" OnClientClick="DownloadMe();return false;" Text="Download File" />

<script type="text/javascript">
<!--
      function DownloadMe(){
       window.open('./DownloadFile.aspx','');
       document.getElementById('<%=btnDownload.ClientId %>').style.display='none';//this line hides Download button on client side by Javascript
      }
--></script>
