use on button client event

onclientclick="return confirm('confirm?');" 

try this:

  function confirmsubmit(){ page_clientvalidate();  if(page_isvalid) {  return confirm('confirm?');  } }   <asp:button id="btnsave" runat="server" onclientclick="javascript:return confirmsubmit()" onclick="btnsave_click" text="save" />
