RadToolTipManager Response Error

[Duy]

Hi,

I encountered an alert error.

RadToolTipManager Response Error:
Sys.WebForms.PageRequestManagerServerErrorExecution; An Unknown error occurred while processing the request on the server. the status code returned from the server was: 500.

This issue occurs when I deployed the onto actual server.  It runs fine on development environment.

Please give me some tips what causes the problem.

Kind Regards,

Duy

Hi Duy,

I advise that you examine this help article that explains how to deal with such exceptions: http://www.telerik.com/help/aspnet-ajax/tooltip-troubleshooting-common-issues.html. You may need to set the customErrors to off in the web.config to see actual exceptions on the deployed application.

Thanks Marin, I used fiddle to look for the problem and further investigation with found related article for similar issue.  (properties  web.config must be runAllManagedModulesForAllRequests="false" and precondition="manageHandler")
