Sys.Webforms.PageRequestManagerServerErrorException ...:500

Ajax Error: Sys.Webforms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was : 500

This issue sometimes occurs when you have a control registered as an AsyncPostbackTrigger in multiple update panels.


Resolution: To solve this issue we need to add below web.config entry to WFS the servers.

<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="100000" />
</appSettings>

<system.web.extensions> <scripting> <scriptResourceHandler enableCompression="false" enableCaching="true"/> </scripting> </system.web.extensions>
