Question

Hi, i am using server side CRUD operations as mentioned in

Data binding in EJ2 JavaScript Schedule control | Syncfusion. I am getting the error as cannto read properties of undefined (reading gettime). I can see my data but i am sure something else is missing. Error seems to be happening in the Js below. I read the other form where they said DOM is not loaded fully.

The properties differed from .NET Core vs Javascript (when it comes to casing of letters) and also my JSON was different.

Hi Naveen,By default, Core to JavaScript camelCase is serialized,
so you need to customize the property names and values. You can refer to the
shared reference link below for serialization and change the JsonNamingPolicy,
as shown in the code snippet shared below.Customize propertyNames: How
to customize property names and values with System.Text.Json - .NET | Microsoft
Learn
 // you need to customize the serialize options and change
the JsonNamingPolicy.

var serializeOptions = new JsonSerializerOptions
  {
      PropertyNamingPolicy =
  JsonNamingPolicy.CamelCase,
      WriteIndented = true
  };
  jsonString = JsonSerializer.Serialize(weatherForecast,
  serializeOptions);
