Json Post size limit increase in MVC 4 - json

Question

I have seen & tried a lot of codes to increase the JSON limit like in
1. web.config
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="2147483647"/>
</webServices>
</scripting>
</system.web.extensions>
2.JSonControllerFactory
public sealed class CustomJsonValueProviderFactory : ValueProviderFactory
{
private static void AddToBackingStore(Dictionary<string, object> backingStore, string prefix, object value)
{
IDictionary<string, object> d = value as IDictionary<string, object>;
if (d != null)
{
foreach (KeyValuePair<string, object> entry in d)
{
AddToBackingStore(backingStore, MakePropertyKey(prefix, entry.Key), entry.Value);
}
return;
}
IList l = value as IList;
if (l != null)
{
for (int i = 0; i < l.Count; i++)
{
AddToBackingStore(backingStore, MakeArrayKey(prefix, i), l[i]);
}
return;
}
// primitive
backingStore[prefix] = value;
}
Down here in GetDeserializedObject() i am getting bodytext as empty and unable to set the max property.
private static object GetDeserializedObject(ControllerContext controllerContext)
{
if (!controllerContext.HttpContext.Request.ContentType.StartsWith("application/json", StringComparison.OrdinalIgnoreCase))
{
// not JSON request
return null;
}
StreamReader reader = new StreamReader(controllerContext.HttpContext.Request.InputStream);
string bodyText = reader.ReadToEnd();
if (String.IsNullOrEmpty(bodyText))
{
// no JSON data
return null;
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
serializer.MaxJsonLength = int.MaxValue; //increase MaxJsonLength. This could be read in from the web.config if you prefer
object jsonData = serializer.DeserializeObject(bodyText);
return jsonData;
}
}
script [down data: jQuery("#geomaster").serialize() contains data. If it is below 100 points the data is saving successfully. if it crosses 100 points, not hitting the controller SaveGeodata method(i mean not posting to controller)].
jQuery.ajax({
type: "GET",
url: "SaveGeodata",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: jQuery("#geomaster").serialize(),
success: function (data) {
alert("Geofence Created Successfully");
},
error: function (msg) {
alert("Error");
}
});
Is there any way where i can attach the maxJsonSize property in script itself.
Any other possible means which could help in posting max data to controller is really thankful.
