Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.
posted

I am using Infragistics v16.1 and have encountered an issue where i have a web data grid with 25 columns and 1000 blank rows. After copy/paste 1000 records from excel and click submit button getting below error: "Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.".

I already set EnableAjax="false" and EnableAjaxViewState="false" and added _callbackManager.setTimeout(600000) in web data grid initialize function.

I already went through some of the posts regarding the same , but not able to find any solutions.

How to fix this issue.should I be able to find this in any documentation?

cheers

Rajesh

    The serialization and de-serialization of returned objects might be the isssue. Check or validate your JSON here also:  JSON Formatter
