Trying to get grid dataSource transport working with Web API

[Robert]

Going a little insane here, trying to bake my own ajax call to reach web api controller method.

Amongst many other efforts:

transport: {
                read: function (options) {
                    $.ajax({
                        url: "api/FlfProd/GetSchedList/",
                        data: {
                            data: JSON.stringify(options)
                        },
                        type: 'GET',
                        dataType: 'json',
                        contentType: 'application/json; charset=utf-8',
                        success: function (data, textStatus, xhr) {
                            //debugger;
                        },
                        error: function (xhr, textStatus, errorThrown) {
                            console.log('Error in Operation');
                        }
                    });
                },
                parameterMap: function (options, operation) {
                    if (operation.toString().toLowerCase() === 'read') {
                        return options;
                    }
                }

 

This reaches the web api, but only if I specify nothing in the controller method signature (i.e. no {} parameter in the Route).

However, when it reaches the server, the parameters are all locked in a single string such as : [0]: {[data, {"data":{"take":10,"skip":0,"page":1,"pageSize":10}}]}.

Using ordinary web service no such difficulty exists, but I want to complete moving to Web API and I frankly hate everything about MVC. Most examples such as Telerik's GridWebApiCrud are ancient and involve MVC. Plus they don't work anymore as far as I can tell.

Really pulling my hair out on this one. Is anybody out there using $.ajax methods successfully with Web API controllers? At the back end I want to use Kendo DynamicLinq as I always have, but I need to be able to bake in the skip, take, sort and filter parameters and I just can't find a way to do it. Filling a grid from Web API that doesn't do any server-side paging is not difficult at all.

Hello Robert,

We have an example which demonstrates how to bind Kendo Grid to WebAPI backend.
