Sys.WebForms.PageRequestManagerParserErrorException
Posted in C#, ASP.Net
This problem also occurs very specifically with update panels when setting session variables. The website thread I linked has a solution to this problem. The difference between the problem linked and problem here is the absence of the methods you listed being used with the same symptoms.

Hi,
I don’t know to wich categories this belongs but SmartNavigation=”true” seems to cause also a “Sys.WebForms.PageRequestManagerParserErrorException”.
Just some tip if you looking for hours just as I did

That is some nice information on how to avoid the error. However, sometimes, this error may be absolutely unavoidable. For example, suppose the case where an Ajax partial-post calls to a database and suppose the database is offline due to a reboot. In such a case, the modal popup will appear in IE to the enduser, who must dismiss it. Furthermore, such popups will stack, such as when the Ajax calls are frequent, such as in a chat application’s polling. My question is– what can be done to CATCH the error, avoid the modal message box stacking, and redirect to show a generic error page? Please advise. Thank you. — Mark Kamoski

I find i only get the error when i have dynamically generated the controls. If i hard code the controls into the aspx page, i don’t get it. If i dynamically generate the controls in the code page then i get the problem on the whole page. I don’t know the answer but maybe this helps.

Can someone give me a tip for this problem?:
I have textbox with user login, button “OK” and updatePanel with label (error messages).
I change login, hit “OK”. Server checks, if changed login is available (must be unique).
– if no, error is shown /* { lblError.Visible=true; updPnlError.Update() } */ – THIS WORKS FINE
– if login is available, i save change and than I WANT TO REDIRECT TO ANOTHER PAGE – How can i do that?? (In (STUPID) IE7, Server.Transfer() and Response.Redirect() don’t work – both shows the PageRequestManagerParserErrorException)
Thx..

yeah i am also facing similar problem, when i click on submit button , it interacts with database… some time it works fine, some times it throws same exception with error code 425…, i really dont understand what to do, becoz thre is no problem in coding.. i ma so sure abt this becoz if there would have problem then every time it would have throw exception which is not happening, one solution i found that to set “enable event validation to false” but this may also cause security issue, hence can not implement this.. can any one give some solution on this pls?

“I’m not really sure why people use Server.Transfer() at all.” Fail.

I don’t know whether someone can truely com up with some perfect solution.

Please, try work on the problem first and then giv ur suggestions.
