You have to set a maximum length appropriate for your Ajax app in the jsonSerialization tag in the web.config file.
Look for this in your web.config file, uncomment and set the size you need:

<!--

Uncomment this line to customize maxJsonLength and add a custom converter -->

For example: <jsonSerialization maxJsonLength="500" />

When you call the web service and invoke a test on the method, the size is not taken into account because who controls the length is the asynchronous communication layer not the web service itself.

Maximum length exceeded - Error

skb — Wed, 08 Nov 2006 03:20:13 GMT

I am currently receiving an error "Maximum length exceeded" when calling a web service method that returns a list of objects. I have not found any configuration entry to set the response max length. If I call the web service (http://localhost/test/locations.asmx) and invoke a test on the method, all works correctly. If I call the web service via the javascript proxy, I receive the error. Does anyone have any ideas? Am I missing something? See code below:
