这是一个简单的例子：

// Server-side
protected void ScriptManager1_AsyncPostBackError(object sender,AsyncPostBackErrorEventArgs e)  {
    ScriptManager1.AsyncPostBackErrorMessage =
        "An error occurred during the request: " +
        e.Exception.Message; 
}


// Client-side
<script type="text/javascript">
  function pageLoad()  {
    Sys.WebForms.PageRequestManager.getInstance().
        add_endRequest(onEndRequest);  
  }

  function onEndRequest(sender,args)  {
    var lbl = document.getElementById("Label1");
    lbl.innerHTML = args.get_error().message;
    args.set_errorHandled(true);
  }
</script>
