Hi,

I have written as following for creating the Schedule

  dataSource: {
                    batch: true,
                    transport: {
                        read: {
                            url: "http://localhost:2237/api/values/GetSchedule",
                            dataType: "jsonp"
                        },
                        update: {
                            url: "http://demos.telerik.com/kendo-ui/service/tasks/update",
                            dataType: "jsonp"
                        },
                        create: {
                            method:"post",
                            url: "http://localhost:2237/api/values/SaveSchedule",
                            data: ,
                            contentType: "application/json;charset=utf-8",
                            dataType: "json"
                        },
                        destroy: {
                            url: "http://demos.telerik.com/kendo-ui/service/tasks/destroy",
                            dataType: "jsonp"
                        },
                        parameterMap: function (options, operation) {
                            if (operation !== "read" && options.models) {
                                return { models: kendo.stringify(options.models) };
                            }
                        }
                    },

in the above in create section how can i pass the object to the api .

In Api

  public void SaveSchedule(Schedular callback)
        {
           
        }

here Schedular is a class consisting of all properties with same name in the ui.

whenever i have saved the data , in the api it shown as callback null.

 

Can you please provide me the solution for this.

 

Thanks,

Hello Siva,

Please note that the request "callback" parameter type is a string (not an object). For more information on the matter you can check the following thread at StackOverflow:

Hello Siva,

Please check the example below which shows how to bind the callback on the client side:

Client side:
dataSource: {
    batch: true,
    transport: {
        create: {
            url: "/Home/Tasks_Create",
            dataType: "jsonp"
        },

Controller:
public JsonResult Create()
{
    var tasks = this.DeserializeObject<IEnumerable<TaskViewModel>>("models");
 
    if (tasks != null)
    {
        foreach (var task in tasks)
        {
            TasksRepository.Insert(task);
        }
    }
 
    return this.Jsonp(tasks);
}

Example JSONP class implementation:
public class JsonpResult : JsonResult
{
    public JsonpResult(string callbackName)
    {
        CallbackName = callbackName;
    }
 
    public JsonpResult() : this("jsoncallback")
    {
    }
 
    public string CallbackName { get; set; }
 
    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }
 
        var request = context.HttpContext.Request;
        var response = context.HttpContext.Response;
 
        string jsoncallback = ((context.RouteData.Values[CallbackName] as string) ?? request[CallbackName]) ?? CallbackName;
 
        if (!string.IsNullOrEmpty(jsoncallback))
        {
            if (string.IsNullOrEmpty(base.ContentType))
            {
                base.ContentType = "application/x-javascript";
            }
            response.Write(string.Format("{0}(", jsoncallback));
        }
 
        base.ExecuteResult(context);
 
        if (!string.IsNullOrEmpty(jsoncallback))
        {
            response.Write(")");
        }
    }
}
 
public static class ControllerExtensions
{
    public static JsonpResult Jsonp(this Controller controller, object data, string callbackName = "callback")
    {
        return new JsonpResult(callbackName)
        {
            Data = data,
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
        };
    }
 
    public static T DeserializeObject<T>(this Controller controller, string key) where T : class
    {
        var value = controller.HttpContext.Request.QueryString.Get(key);
        if (string.IsNullOrEmpty(value))
        {
            return null;
        }
        JavaScriptSerializer javaScriptSerializer = new JavaScriptSerializer();
        return javaScriptSerializer.Deserialize<T>(value);           
    }
}

Hi Vladimir ,

the following method i can't replicate 

public JsonResult Create()
{
    var tasks = this.DeserializeObject<IEnumerable<TaskViewModel>>("models");

    if (tasks != null)
    {
        foreach (var task in tasks)
        {
            TasksRepository.Insert(task);
        }
    }

    return this.Jsonp(tasks);

Hi,

Currently we have no complete demo which we can provide - that could you please provide the (runable) sample project where the described issues can be reproduced? This I will get better overview of the exact setup that you have and advice you better how to proceed.
