Hello friends,
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12031
I am getting this error when i am saving to database.
If I understood you correctly, it is an UpdatePanel problem in your page, here is the solution set EnablePartialRendering to false in the ScriptManager
I think it may help somebody
Please first check your Asp.Net Ajax Extension and Ajax ControlToolkit (if been used) ' s version. Update to the latest.If not, you should check your settings such as web.config and your C# code.
By the way , based on the error description, it looks mostly like some setting errors.
12031 ERROR_INTERNET_CONNECTION_RESET
The connection with the server has been reset.
If your problem cannot been resolved , please share more code.
If you're getting that from an updatePanel, set
EnablePartialRendering="false"
in the ScriptManager for the page, and then it should give you the actual error.
Also, if it only happens occasionally, I've found that it could be a viewstate problem, especially when the page goes a long time (20mins or so) between refreshes.
Otherwise, try some try/catch blocks. Those are some easy methods.
Hope that helps!
Thanks
I have seen this error occur when a button is clicked from within an UpdatePanel and the session has timed out. You can trap this error by adding a javascript error handler.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function
EndRequestHandler(sender, args) {
if
(args.get_error() !=
undefined
) {
var
errorMessage;
var
error = args.get_error;
if
(args.get_response().get_statusCode() ==
'
12031'
) {
errorMessage =
"
Session Timeout."
;
else
if
(args.get_response().get_statusCode() ==
'
200'
) {
errorMessage = args.get_error().message;
else
{
errorMessage =
'
An unspecified error occurred. '
;
args.set_errorHandled(
true
);
alert(
"
An error occurred: "
+ errorMessage +
"
Please refresh the page to restart your session."
);
Hope it helps!!
Thanks
