Error during serialization or deserialization using the JSON JavaScriptSerializer

Hello,

With certain files I get that error:

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

given that in my web.config I have the following:

it doesn't even go inside the controller in the backend.

Kindly note that I use vue.js for the frontend.

Hi Omar, 

 

Thanks for contacting Syncfusion support.  

 

Our PDF Viewer control is client-server based. So we send the data as JSON object between client and server. We suspect that the reported issue occurs due to the serialization of the large-sized JSON object.  

 

We need to increase the maximum length for serializing the large-sized JSON object.  

 

We have created a sample for the same, where a class is added (LargeJsonValueProviderFactory). Also, the code is modified to increase the length for serialization in the file LargeJsonValueProviderFactory.cs.  

 

Kindly download the sample from the following link.
