Json not working with Kendo Ui Grid #18003

Closed davidbuckleyni closed 4 years ago

davidbuckleyni commented 4 years ago

I am having a major issue with .net core 3.1 and the kendo ui asp.net core grid supplied by telerik. This appears to be a .net issue and not Telerik.

As you see I have included my source of my startup.cs

` public void ConfigureServices(IServiceCollection services) { services.AddControllers(); services.Configure(Configuration);

        services.AddHttpClient("externalservice", c =>
        {
            // Assume this is an "external" service which requires an API KEY
            c.BaseAddress = new Uri("https://localhost:5001/");
        });
        services.AddSwaggerGen(c =>

        {
            c.SwaggerDoc("v1", new OpenApiInfo { Title = "Api For RoundTable A Complete ERP for warehouse managment", Version = "v1" });
        });

        services
            .AddControllersWithViews()
            .SetCompatibilityVersion(CompatibilityVersion.Version_3_0)
            // Maintain property names during serialization. See:
            // https://github.com/aspnet/Announcements/issues/194
            .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
    }`

My Api Call

` public async Task<List> GetStockFromApi(){ List _result = new List();

        var uri = new Uri(string.Format(Constants.GetALlStock, string.Empty));

        var response = await _httpClient.GetAsync(uri);
        if (response.IsSuccessStatusCode)
        {
            var byteArray = await response.Content.ReadAsByteArrayAsync(); 

            var content = Encoding.UTF8.GetString(byteArray, 0, byteArray.Length);
            _result = JsonConvert.DeserializeObject<List<Stock>>(content);
        }

        return _result.ToList();
    }

` I have used postman to check my json response and noticed that it is still coming in lower case. However, the data objects deserialize ok but I am having real trouble in getting my kendo ui grid to bind. This approach worked fine in .net 2.2 and .net core 1 image

p-m-j commented 4 years ago

If you can deserialize just fine, how is this a .Net issue instead of a kendo.ui issue or just plain user error?

kakone commented 4 years ago

Add this line in your Startup.cs file : .AddJsonOptions(opt => opt.JsonSerializerOptions.PropertyNamingPolicy = null)
