问题描述
大家好,
单击按钮,我试图在excel工作表中下载大量数据.此按钮位于Ajax:更新面板中.现在发生的是,当我尝试下载保存在更新进度中的进度图像时,它会出现并停留很长时间.过了一段时间,我得到了这两个错误:
1. Sys.WebForms.PageRequestManagerTimeoutException:服务器请求超时
2.Sys.WebForms.PageRequestManagerServerErrorException:在服务器上处理请求时发生未知错误.服务器返回的状态码为:0
我确实了解到此错误是由于异步回发超时而导致的,我将其保持在大约600.但是,如果数据更繁重且需要更多时间,该怎么办.此外,我在3.5框架中创建了该网站,现在由于将其转换为2.0框架,因此我也更改了一些下载机制的代码.甚至我添加了
Hi All,
I am trying to download a huge amount of data in excel sheet on a button click. This button is inside Ajax: update panel. Now what happens is that when i try to download the progress image kept inside update progress appears and stays there for a long time. After sometime than I get these two errors :
1. Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out
2.Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0
I do understand that this error comes because of asynchronous post back time outs and i kept it approx 600. But what If data is more heavy and takes more time. Moreover I created this website in 3.5 framework and now i have shifted it to 2.0 framework due to which I changed some coding too for downloading mechanism. Even I added
script language="javascript" type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequest);
function endRequest(sender, args)
{
// Check to see if there's an error on this request.
if (args.get_error() != undefined)
{
//$get('Error').style.visibility = "visible";
// Let the framework know that the error is handled,
// so it doesn't throw the JavaScript alert.
args.set_errorHandled(true);
}
}
</script>
