I am getting following error message:

EXCEPTION: System.InvalidOperationException: The JSON request was too large to be deserialized.
   at System.Web.Mvc. JsonValueProviderFactory. EntryLimitedDictionary.Add(String key, Object value)
   at System.Web.Mvc. JsonValueProviderFactory. AddToBackingStore(EntryLimitedDictionary backingStore, String prefix, Object value)

   at System.Web.Mvc.ValueProviderFactoryCollection.GetValueProvider(ControllerContext controllerContext)
   at System.Web.Mvc.ControllerBase.get_ValueProvider()

Also, I added in web.config:

<system.web.extensions>
    <scripting>
        <webServices>
            <jsonSerialization maxJsonLength="2147483623"/>
        </webServices>
    </scripting>
</system.web.extensions>

But not working for me.

I think, you can set a higher value for aspnet:MaxJsonDeserializerMembers in the appSettings:

<appSettings>
 <add key="aspnet:MaxJsonDeserializerMembers" value="160000" />
</appSettings>

Also you can see on https://msdn.microsoft.com/en-us/library/hh975440(v=vs.120).aspx

It specifies the limit of the maximum number of items that can be present in any dictionary deserialized by the JavaScriptSerializer type.

Type:	Int32
Default value:	1000
Remarks:
Example:	`<appSettings> <add key="aspnet:MaxJsonDeserializerMembers" value="1000" /> </appSettings>`
