Hi,

I've got the next problem:  'Sorts' parameter of DataSourceRequest is null.
I've found a few threads here with similar issues but the only difference is that i'm not using MVC wrapper for Kendo Grid. Also I can confirm that MVC wrapper works perfectly in my case, but I need to manage grid without it.

Here is the simple sample of what i've got now. What I'm doing wrong?

My scripts bundle:
- jquery.min.js 
- kendo.all.min.js 
- kendo.aspnetmvc.min.js

Kendo Grid declaration:
 $('#cars').kendoGrid({
            pageable: true,
            sortable: true,
            dataSource: new kendo.data.DataSource({
                serverPaging: true,
                serverSorting: true,
                schema: { data: "Data",  total: "Total" },
                transport: {
                    read: {
                        url: '@Url.Action("GetCars")',
                        contentType: "application/json; charset=utf-8",
                        type: "POST"
                    },
                    parameterMap: function (data) {
                        return JSON.stringify({ request: data }); 
                    }
                }
            })
        });

Action:
public DataSourceResult GetCars([DataSourceRequest]DataSourceRequest request)
{
    ............................
}

HTTP request parameters:
{"request":{"sort":[{"field":"Name","dir":"desc"}]}}

Thanks!

Hello Max,

May I suggest you to use Kendo UI Grid MVC wrapper instead? It hides a bunch of logic required to send the content in proper format to the server in order to be properly parsed by MVC framework. Using Kendo UI MVC wrappers will do the proper DataSource setup for you.

Otherwise the data source configuration should looks similar to this:

You will also have to remove your implementation for parameterMap as `type: "aspnetmvc-ajax"` will provide you with default one which will format the data in a way that ASP.NET MVC ModelBinder understands.

Hi There,

I am using Angular, KendoGrid, with MVC5 but The Sort/Group/Filter is always null in controller regardeless of what i have tried. I read many thread and i believe i am doing what i should do but the value are null. Please let me know what the issue is.

                    }
                }
            }
        });
</script>

 

And the controller look like this:

 

public class HomeController : Controller
    {
        private MyContext db = new MyContext();

    [HttpPost]
        public JsonResult GetSupplier([DataSourceRequest] DataSourceRequest request)
        {
            DataSourceResult result = db.Suppliers.ToDataSourceResult(request);
            return Json(result, JsonRequestBehavior.AllowGet);
        }

}

Hi There,

I am evaluating KendoUI using Angular, KendoGrid, with MVC5 but The Sort/Group/Filter is always null in controller regardeless of what i have tried. I read many thread and i believe i am doing what i should do but the value are null. Please let me know what the issue is.

I have inserted the code in a separate file.

Hello Laurent,

I examined the provided code and as far as I can see it looks correct. For your convenience I prepared a small runnable sample and attached it to this forum post. Could you please check it out and let me know how it differs from your real setup?

Hi Kostadin, 

I have download your example but was missing a valid Kendo.mvc in the package so i used NuGet to update the project. 

Now the project starts but crash straight after beginning. 

regards, Laurent

Hi Kostadin, 

I cannot see any difference between my project and your project. To my own interpretation, the only way the DataSourceRequest parameter can be set is from the client side and server side. From the browser the following form data are sent:

sort:Name-asc~OfficeAdresID-asc
page:1
pageSize:15
group:
filter:Name~eq~'1'

Please check this is correct format. Then it is all about the parsing on server side. This is done automatically with the mapping method.

public JsonResult GetSupplier([DataSourceRequest] DataSourceRequest request)

Which i have no control over. So what is necessary to make this line work properly?

Regards, Laurent

Hi Laurent,

Could you please verify that you are including kendo.aspnetmvc.min.js in your project? Also you can check for any client exception which might prevent passing the parameters to the server. I would appreciate if you prepare a small runnable sample and send it to us in order to examine it locally.
